Hi Jafro, I'm actually one of the few people who you said would actually take on this task. I am currently building a high RPM N/A miata engine and I've used most of your tips and applied it to my cylinder head, intake manifold, heat shield, valve cover, coolant neck, inlet tube, timing cover, oil dipstick tube, and engine hoist hooks. I also checked out your other video about porting and polishing combustion chambers and have done the same with my head. I just want to thank you for uploading these videos because without them, I'd still be struggling pretty hard to develop a proper method to polishing metal properly. Especially with looking for how the light bounces off sanded metal bit. I used to have a vague idea of what to look for but you were able to clearly define it which has really sped my process up. I do want to ask though: what do you think of diamond compound paste? The only thing I didn't follow was polishing because I wanted to try my own method of it. Once I had finished with 400 grit sandpaper, I would use black emery, brown tripoli, then jewlers rouge. Then I stepped down to 320 grit diamond paste and slowly move up to 200,000 grit diamond paste with 50% diamond concentration. Around 4000 grit I would use regular metal polish though. If you'd like to see the results of my work, I'll be very happy to oblige :)
Bro if you make the video, I'll watch it! I have always stuck to the solid compounds. I use the pastes and final finishing products by hand. I know that diamond paste is made for machine applications, but I've never been that fancy. I'd love to see what it does!
I polished the whole supercharger, snout, etc on my Hellcat. People look at me puzzled when they find out it took 230 hours not including stripping the factory paint. Finally, I feel like a group of people that understand me. Even most car enthusiasts don’t understand!! Thanks for taking the time to show the effort and the art!!
@@RollingRoadEFI Not DNA, but the 2g's were built in a Chrysler plant in IL. They have Dodge Avenger door handles. Chrysler being a Diamond Star member and all... Couldn't have done it without 'em!
Your videos and voice-overs are the best on TH-cam. Thank you so much for everything your willing to share. You have no idea the amount of information that you provided over the years that helps with so many other makes models and engines! Looking forward to your gsx assembly. Keep doing what you do!
Idk what any of us dsm enthusiasts would do without JafroMobile youtube videos 😂 most knowledgeable guy and never leaves out any small detail. I can't tell you how many people I've referred your channel to. I know this video isn't recent but i appreciate all that you do 👍 I remember doing my valve cover... it took me a week to finish.
if you polish a motorcycle engine its smaller and faster than a cylinderhead, i apreciate your time of not only doing the work but also filming it wring and editing! Cheers men, if some day il travel to the US i buy you a beer!
HF die grinder died at 2 1/2 cylinder heads with a potentiometer inline when the switch assembly burned up. Had to finish with a HF 3/8 drill , $25. I can replace the switch with a universal 4 pin toggle. Great video series. In the late 70's my shop teacher had me hand sand/shine a metal blank for a month till I could buff it. Old school.
ill add for PPE whenever i work with fibrous material or metal dust i always use baby powder on my skin. it fills the pores and prevents contaminants from getting in. also makes cleanup much easier
Instant subscribers! Thank you for the video. I've been learning Aluminum buffing over the last 3 months and it's been a learning process. You video came to me at just the right time. Thank you. Its hard to find good educational videos about this. Not a lot have created or developed a pedagogy like you have. It's a fascinating process. Cheers
Even though I’m a big wuss that can’t handle the dismal parts availability that you DSM guys put up with I still enjoy your videos Jafro. Subaru spoils us softies that can’t commit to the DSM life.
Are we going to see a polished Valve cover and block too? It’s amazing how far this polishing job has come. 🤩 man it looks fantastic! But, I know you’re gonna make it look even better. Love the content detail and explanation on materials.
Ahhh i can breath & relax again Jafros back thanks for the knowledge bomb, now i know what to purchase so i can polish the exterior of the head , please don't take so long with your next video as i keep turning blue holding my breath lol
I think the best part showing this is to 'explain' to people just how labour intensive metal polishing is plus it's often a dirty smelly job. I only tried it professionally for a few weeks during summer vacation almost 50 yrs ago . My father was a professional metal polisher and didn't want me going into the same line of work. (I didn't) Personally, I have a few Sisal wheels but they don't get used much as I mostly do cast or 6061 aluminium. Even steel polishes very well with stitched mops and emery compound. A 1hp motor is about minimum for a pedestal polisher professional models are up to 5hp with 3hp being 'normal' I use a 2hp from Harbor Freight but it's been discontinued for several years and can be stalled quite easy with a new 10" mop. Loose wheels with blue compo actually work well polishing plastics but you need a light touch to avoid melting the surface (I've done a few motorcycle windshields in poly-carbonate and some acrylic sheet) As you found out, the HF die grinder doesn't have enough torque for metal polishing but it quite adequate for use with carbide burrs if you do any porting
Out of all content creators, I love Jafro voice overs by far the most. You're educational, interesting, entertaining and very inviting. Happy Thanksgiving, my friend. 🤘
It's so shiny that I'm pretty sure that I could see my face in it. Impressive and worth the effort. I'm looking forward to seeing the trophies that I know you will win!
wow thank you jafro for helping me understand all the different kinds of wheels and compounds and when and how to use them, im finally confident to start my step 8 now sensei!
A good tip! Do yourself a favor. Go to your local rental store and rent that electriic die grinder. You might have to get the insurance seperate but it pays. You can get a heavy-duty name brand tool and if / when the bearings go out or it burns up you just take it back and they give you another one. Its a good move when port matching intakes and heads.
You were the first channel I supported, and I will continue to do so, this content is just too dang good to consume and not give you a little back in return. I have a Subaru EZ30D going together next year, but I don't think I will be polishing it. There is a certain method that you use in all your projects I hope to replicate.
I have this exact die grinder except it's blue and I got mine for $69.99 at princess auto on sale! I picked up a variable vent speed adjuster and now it's variable speed for under $100!
Im about half way through watching right now. And what I can say about this vid so far. Is I'm impressed. Full live audio explanations. Fuck all cuts, clear, no mistakes, um ahhs or pauses. I know how hard that is. You've always done amazing audio voice-over work. But this is hard AF and you've killed it despite it not being your style. Can't wait to see the actual polishing. But 15 mins in you've gained another level of respect mate.
I edited a few of them out, but I was on a roll. You're right, it's not my style. Not everyone can put themselves on camera and regurgitate a coherent point. That is a talent that I even don't really have. I contemplated shooting silent scenes for a VoiceOver and then realized the VoiceOver process won't let me leave the material I already shot in tact. It would leave me re-shooting several things so that it flowed right. I knew it would be hard to shoot an hour of silent scenes to VO and put them together. I knew what I wanted to say and what all this was for, so I just did it all twice, spoke from experience and kept the good parts. What I was happier about was how my predictions all proved themselves correct before we bruised a wheel or a buff (or the die grinder). Some people are on-camera naturals who can juggle the camera, their crowd of friends, and a multi-part conversation with the viewer, and their environment to still create a natural, flowing, coherent scene complete with funny quips and insults with their mates. My normal video style developed not because I have that talent. :P Thinking about editing the description of 100 different kinds of tools made me pretend like I do!
Hey Jafromobile, I’m in the beginning stages of my 4g63t build. I know my question isn’t related to this video, but I’ve been rewatching a lot of your old 4g63 videos. One particular thing that’s been bugging me is on the topic of the oil filter housing. Long story short, I have a 95-99 7 bolt (came with a balance shaft delete) and I want to use that engine for an Evo 8 build. If it can’t be done, please stop me while I’m in the beginning stages before I waste my money 😂! Here’s my question: can I use the Evo 8/9 oil filter housings on this older 7 bolt? I know you get a lot of comments. I hope you take the time to read this one. Thanks in advance and keep those videos coming!
Great stuffs Jafro!! Always excited with new videos but it kinda sorta bothers me that the audio is not the best. I know your voice over is great! The in camera audio is not the best, but hey it way better than some of these starting up channels. just a little constructive criticism. Please keep on doing what you do 👍👍👍👍
Is it the buzzing of the lights? Because I found a 60Hz filter than nukes that, but it makes me sound a bit nasal... and a bit digital if that makes any sense? But knowing where in the video vs. the problem is helpful. The shop is a big square concrete box and it does tend to resonate. Using a lavaliere mic might help with that...? Or perhaps anything other than a shotgun mic?
@@Jafromobile Its partly the buzzing and the reverberation from the walls. Also sometimes you would walk away from the camera and be outside of the mic pick up pattern. I really noticed it from 3:00 to about 4:40. I was just expecting spectacular audio from your videos and that the only reason I bring it up. Tom's Turbo Garage and yourself in my opinion always had/have spectacular audio quality.
I could tell the sound setup was different, but it's worth noting that the change did not bother me at all. Your time is the main constraint, so if a minor compromise in some other area saves you time, it's probably a net gain. If audio becomes a problem, personally I'd rather record cheap audio on set as a reference, and voice-over in the edit suite. Bonus: I can play music on set, as long as I'm not recording ambient sounds that need to be in the final cut.
@@LeonBuilt Go to 13:04. 3 seconds later... that's when I found the 60Hz filter. It makes my voice thinner because apparently I have 60Hz overtones... but POOF, hum of the lights disappears. It's something I can use to fix the shop hum, but it doesn't fix all the reverb. Keep using the filter?
@@Jafromobile When I first hit that part of the video I thought my internet speed had fluctuated. I live in a rural part so speeds are not the best. Now that you mention it I do notice the dulling of sounds and the voice change. I would suggest omitting the 60htz filter. I can live with the humming instead of the dulling effect. Perhaps in the future a LED shop light upgrade. I would highly recommend the (Barrina LED Shop Light, 8FT 72W 9000LM 5000K,(Pack of 10) can be found on the Amazon) great upgrade from my own experience. Taylor ray has an awesome video about these lights. (First Upgrades to My New Shop! Huge Improvement! 13 mins in). This is one persons suggestions, please go about this issue according to your thoughts and the communities feedback. Thank you Jafro .
Keep all polishing tools in a clean sealed environment. I don't know how many times I've had guys ask me to fix their polishing after they decide do go after something with a wheel, bonnet, what ever, that has been out in the open for years. They are packed with silica, metal oxides from other processes in the area. Personally unless it is getting plated. The hell with polishing. Lot of work for short term win, with a long term failure. I paint everything.
Just curious, could you use vapor honing for some of the intermediate steps? With the setup I have, I'm able to get really nice results and bring out the fine details, but obviously not to the chrome-like finish you get to by the end.
Oh, BTW, I very rarely use more than 600 grit emery cloth or paper for prep even on sand-cast parts and 400 is often more than enough when starting with a hard wheel
Jafro, I’ve got a bit of a silly question. What happens to the brilliant finish when you take the head to the machine shop and they wash it in their parts washer after machine work?
I though of you! I made a playlist. The first video in the playlist is me doing exactly what you just asked. You see... this ain't my first rodeo. Not only have I done it before, but I've rebuilt my other polished cylinder head twice and had to completely re-polish it. First video in the Polishing Aluminum playlist is my old G6K fresh out of the hot tank. ;)
Actually that's a good point. You could use something like a Dremel and a ball endmill. Maybe don't shoot for polished but instead make the character consistent, like engine turning.
About the protection. Enough is never enough. My dad got mild copper poisoning from cleaning old fireplace pot. Weared long sleeves, gloves and two KN95 respirators, just the dust that got on his face made him sick 2 days straight.
Printed metal foil label had the model and serial on it, wore off 20 years ago. Now it's a blank metal foil label. Believe me I wanted to scour the internet to find another one but came up blank just like that label. There's no molded model or serial numbers anywhere on it. I have the exact same question as you do!
@@Jafromobile I'm surprised they weren't stamping serials...ink seems weak-sauce for that era Milwaukee. Even my old 3/8ths junkie toy circa 80s I think was stamped..anyways.. I scoured ebay, it looks like the 5194 (5 amp) or 5196(11 amp?). The 52.. series are still being made it seems, China style, but there is 100% a difference between the USA made Milwaukees and the China versions. (For realz. Aint racism, just truism. Try out the old Hole Hawgs from the Wisconsin plant originals vs the newer China ones...) Everything on ebay seems real overpriced so it seems like people are onto it :o If you can take high res pictures/give me dimensions of the shank, the collet, the length of grinder between the bit and the trigger, I can further scour the intertubes. I wonder if zee Germans have an equivalently good Fein secretly hidden away from the US market.. their 4.5 and 5" angle grinders cost around as much as the rat tail Makitas and last just as long. Your cable looks like its gonna fray off. I'd pre-emptively replace them with a nice SJOOW or SOOW (oil resistant, water resistant) CSA approved @ 105c (125c is overkill) cable. Also replace the carbon brushes if you want. I'd open that up though, and pre-emptively change the brushes. My mom (lol no joke, she's hardcore with tools) picked up a lot of tools from garage sales in the 90s, which were from the 70s and 80s era...just keep the brushes happy and I bet you'll get another 10 years outta it. A+ A+ A+ Jafro 4eva
Excellent results Jafro!!! I’m here again 😅 trying not to talk about the forbidden path so I don’t get scolded like last time 😬 (wet vapor honing), but I really DO what your opinion......Given you’ve completed ALL the time intensive / foundational steps, do you PERSONALLY think that it could be beneficial as an additional / final step in getting uniform blending around some of the hard to reach corners and letters, WITHOUT messing up the finish you worked so hard to achieve currently??? I’m asking this because I’m doing a set of motorcycle cases / cylinder in basically the same way as you’ve outlined in the last 8-videos...
It'll do it! But one thing it will also do... it's gonna change the font. In the video I mention the casting is very porous around the lettering. It's a lost wax and sand process. The detail work around the lettering tends to crumble when the molten aluminum hits it so grains around the letters break up slightly and leave the detail pitted. It's not severe enough to compromise the part, but it's rough enough that you can't get inside or between the letters smooth. You can definitely make it smooth-er with a vapor blaster, but to dig deep enough to take out that rough cast, you're going to change the font. It will round edges if you do it long enough to make it smooth-ish. But I'm not being a defeatist. I'm being an acceptist. I accept there's no good way to make it perfect. Vapor blasting will help you smooth parts for polishing. The only thing it lacks in this whole process is the ability to plane the part flat. The techniques that plane a surface flat won't get the detail in the letters and a vapor blaster would. The vapor blaster will get all of that detail work accomplished, but it will round off the edges just like the black rouge will. It will do it before you start with the black or brown rouge which will round it further. I know vapor blasting is touted as a non-destructive process, but it's not. It's just really slow to "destroy" things compared to other types of media blasting. It's less-destructive, not non-destructive. Sometimes you have to destroy things, crack eggs to make an omelette kinda thing... even my manual methods will do that but once polished, these methods all create their own effect. I mention in early videos the "arsenal of weaponry for polishing aluminum". Vapor blasters, media blasters, tumblers, and also everything I've demonstrated in my old school methods are all part of that arsenal. There are no wrong answers. Only different methods for conquering different kinds of shapes and problems. I suppose I wanted to demonstrate the sub-$100 method that's been around for over a century as the foundation of the process so that the one doing the job understands it and adapts other processes to their particular piece of work. Vapor blasters save time but they're out of reach for many people who want to start this, and my example demonstrates you can win trophies without it. That's the method that worked for me, and why I preferred to share it. You never made any sort of list or turned into any sort of problem child, lol! You always asked or suggested a valuable option. Happy Thanksgiving!
Man it looks like a mirror and your Not even done yet your going to be Able to bling the Moon with just your cylinder head this reminds me of the Cylinder head porting video have happy Thanks giving jafro
Sure are lucky to have Harbor Freight at hand, even if their items are questionable (china made) Here in the UK there's no main shops that you can walk in and buy such items, has me wondering what people did prior to the internet. Also a large flex shaft for a bench grinder would be ideal to use the 1/4 shank, i've been searching for one for a long time with no luck, the guys in India uses them when re-treading tyres.
They went to car meets that mailed out newsletters to learn how to do new things and see other people's work, and I suppose they bought $20 die grinders out of the trunk of cars not understanding that the seller would then go spend that money on crack. Seriously, I was so young and stupid. I don't know if it was stolen or not, but it's not even the item he was trying to sell me. He had a great hard-luck story that made me sad, I just wanted to help. I needed nothing he offered, I said "what about that?" and pointed at it. I didn't know how that worked. Naive. Gullible. Yes, Harbor Freight is much more convenient! Additionally, if that exchange didn't happen, I might not have ended up with the right tool the first time I tried to do this, failed, and then quit without achieving any of my success because this tool was actually hundreds of dollars outside of my price range at the time. There was no harbor freight back when there was no internet. Tools used to cost a fortune when I was young because they were all made here in the US, and marked up a half-dozen times during distribution. But, they certainly were built well! Which begs the question... how big of an impact has harbor freight had on the young automotive hobbyist today that put all the formerly-expensive tools within reach? Or the internet that brings you the information you used to have to get by traveling to events to meet the people who do this kind of work to ask the questions. It's pretty cool that I can share all this with someone curious about it 3,540 miles away for $0.
Yes, so this whole process counting in years probably already and countless hours of work OR polishing machine with ball bearings vibrating every corner of that engine head ?
Loud and clear, dawg. 🤍 This blingy head is just one part of a complete car restoration. There are a whole lot of moving parts and a lot of different shops involved with all the different pieces of two cars' restorations. It takes time and a whole lot of $ to produce the results I'm about to unveil on both restorations. Many parts came back recently, and I've been working with the ones I have. I'm about to upload a video of over a hundred pieces rebuilt, restored, assembled, replaced that took a whole year to complete. My next video upload makes the car roll out, and it gets me the space I need for exactly what you want to see. I've got 1h15m of it voiced. Whenever I'm gone for a while in your feed, I'm about to drop something really epic!
Since i already have the machinery to make them, i haven't bought wheels in a long while. Whilst indeed some prices reflect the quality of the end product, they don't reflect the actual manufacturing price.
and i bet ereybody this whole time was under choking out the side of a neck snooting, that this old cat and his dang hyundais werent what was the buisiness, while this man just flexed the 90s whoop there it is! the mans a true mr clean, sir don the one lord clout... freshed us up on all of us wannabes.
Lets be honest for 1 minute. My PT Cruiser, will never get this treatment, nor does it deserve it. However, I can not applaud the effort you have gone through to document this process any harder. This is the kind of content I would select for the "Knowledge Humans Possessed" In the alien museum erected on the charred remains of our civilization.
Yep! I know... while I did make 6 videos about this thing, I made 23 videos total between TH-cam and Patreon over this exact same stretch of time. The first one took me 3 months of non-stop work every day around my day job, no cameras, no editing, no instruction, just continuous non-stop work. I'm actually surprised that producing this along with 17 other videos that it didn't take me longer to do. Making a video about a thing usually takes 10 times longer to do than just doing it.
I have just finished restoring the engine for my Peugeot 205 Gti, an xu10j2te, with forged pistons and rods, with a disco potato and DTAfast management for more power. Anywho i purposefully left my cylinder head completely full off white aluminum corrosion and impurities, simply to annoy people that polish their engines like this. Chrome won't get you home and all that. I will never understand why people do this. So much work for basically no reason at all.
With dentist drills, teeny tiny tools, numerous tiny wheels and diamond paste. Not that I've done it. I've just never found the rotary tool I want. The one I'm looking for is a foot-pedal controlled antique with an articulating arm. My mom had one when I was a kid and it was incredible. Very comfortable but somewhat dangerous due to the 7 foot long external belt and pulley system making it just a little bit more fun. Put your hair away. It was a workhorse with tons of torque that could do everything detailed and heavy enough that it made it extremely steady. I'm not willing to use a Dremel for that level of detail. Modern dentist drills are quite a considerable investment. But I'm like you, I like the character.
lol pretty ballsy running those wheels so fast. Those eastwood buffs are apparently only meant for 2500rpm but electric die grinders are going at ~25000rpm. Good call on the safety gear! I might have to try it on some mold polishing. I only ever use a drill. Very slow... Kudos to the milwaukee for not dying. I killed my makita bearings running too large of a tool. Now i reserve that for burrs only. and sanding/cutting discs go on a pneumatic one now.
Oh, I know! I've actually always done it this way, though. That's precisely why I did mentioned it right along with the safety gear, and encouraged people to upgrade it. The wheels do blow up from this sometimes, but you do get more done faster like this. You should follow the recommendations for the most part, but there are circumstances where it helps you if you don't. If these were cutoff or grinding wheels, there's never an excuse for exceeding the RPMs. When polishing wheels blow up, it's more like a teddy bear exploded than being caught inside a meteor shower. It mostly just makes a big mess.
Me at the start of this; "I'm gonna polish my timing covers and intake manifold" Me 5 minutes into step one; "I'm gonna paint my timing covers" What I'll actually do: Clean them with some brake cleaner, while appreciating your hard work instead
20:43 yup. Honestly, if you don't use those ppe you're not a professional, you're an amateur. A foolish one at that. Your product will be inferior and you will injure yourself whether you know it or not.

Hi Jafro, I'm actually one of the few people who you said would actually take on this task. I am currently building a high RPM N/A miata engine and I've used most of your tips and applied it to my cylinder head, intake manifold, heat shield, valve cover, coolant neck, inlet tube, timing cover, oil dipstick tube, and engine hoist hooks.
I also checked out your other video about porting and polishing combustion chambers and have done the same with my head.

Then I stepped down to 320 grit diamond paste and slowly move up to 200,000 grit diamond paste with 50% diamond concentration. Around 4000 grit I would use regular metal polish though.

A 1hp motor is about minimum for a pedestal polisher professional models are up to 5hp with 3hp being 'normal'
I use a 2hp from Harbor Freight but it's been discontinued for several years and can be stalled quite easy with a new 10" mop.
Loose wheels with blue compo actually work well polishing plastics but you need a light touch to avoid melting the surface (I've done a few motorcycle windshields in poly-carbonate and some acrylic sheet)
As you found out, the HF die grinder doesn't have enough torque for metal polishing but it quite adequate for use with carbide burrs if you do any porting
Out of all content creators, I love Jafro voice overs by far the most.
You're educational, interesting, entertaining and very inviting.
Happy Thanksgiving, my friend.
🤘
I wrap a cloth type bandage tape around the collet on whatever I'm polishing with to avoid those scratches when reaching in those tight angles.
It's so shiny that I'm pretty sure that I could see my face in it. Impressive and worth the effort. I'm looking forward to seeing the trophies that I know you will win!
Nothing is shinier than you!
Hell yeah, long time coming but awesome too see the final piece.
wow thank you jafro for helping me understand all the different kinds of wheels and compounds and when and how to use them, im finally confident to start my step 8 now sensei!
Love the long format jafro. Nerdy techy content but somehow very entertaining.
Totaly agree! It really is a labour of love and persistance. John.
Alright now I'm done watching. That's straight art.
Thanks for the videos Jafro! The “G6S” looks great btw.
New episode of Jafro yee boi 🔥🔥🔥
*HAPPY THANKSGIVING JAFROMOBILE* 🦃🥧🍽
There’s a lot to give thanks for this thanksgiving and a Jafro video is on that list!!! Thanks Jafro and Happy Thanksgiving!!! 🦃
Nice camera work too. I've been working on that recently as well.
Jafro been following you for years and always look forward to your videos ... my god all that time to make it shine looks beautiful....
Love you Jafro
A good tip! Do yourself a favor. Go to your local rental store and rent that electriic die grinder. You might have to get the insurance seperate but it pays. You can get a heavy-duty name brand tool and if / when the bearings go out or it burns up you just take it back and they give you another one. Its a good move when port matching intakes and heads.
You were the first channel I supported, and I will continue to do so, this content is just too dang good to consume and not give you a little back in return. I have a Subaru EZ30D going together next year, but I don't think I will be polishing it. There is a certain method that you use in all your projects I hope to replicate.
Nicely done bruv!
looks beautiful!
I have this exact die grinder except it's blue and I got mine for $69.99 at princess auto on sale! I picked up a variable vent speed adjuster and now it's variable speed for under $100!
Jafffrooo! Top content as always :)
Im about half way through watching right now. And what I can say about this vid so far. Is I'm impressed. Full live audio explanations. Fuck all cuts, clear, no mistakes, um ahhs or pauses. I know how hard that is. You've always done amazing audio voice-over work. But this is hard AF and you've killed it despite it not being your style. Can't wait to see the actual polishing. But 15 mins in you've gained another level of respect mate.
I edited a few of them out, but I was on a roll. You're right, it's not my style. Not everyone can put themselves on camera and regurgitate a coherent point. That is a talent that I even don't really have. I contemplated shooting silent scenes for a VoiceOver and then realized the VoiceOver process won't let me leave the material I already shot in tact. It would leave me re-shooting several things so that it flowed right. I knew it would be hard to shoot an hour of silent scenes to VO and put them together. I knew what I wanted to say and what all this was for, so I just did it all twice, spoke from experience and kept the good parts.
What I was happier about was how my predictions all proved themselves correct before we bruised a wheel or a buff (or the die grinder).
Some people are on-camera naturals who can juggle the camera, their crowd of friends, and a multi-part conversation with the viewer, and their environment to still create a natural, flowing, coherent scene complete with funny quips and insults with their mates. My normal video style developed not because I have that talent. :P Thinking about editing the description of 100 different kinds of tools made me pretend like I do!
@@Jafromobile Dude you killed it, and also I have neither ability live nor voice over in post.
that looks great bud!
Hey Jafromobile, I’m in the beginning stages of my 4g63t build. I know my question isn’t related to this video, but I’ve been rewatching a lot of your old 4g63 videos. One particular thing that’s been bugging me is on the topic of the oil filter housing. Long story short, I have a 95-99 7 bolt (came with a balance shaft delete) and I want to use that engine for an Evo 8 build. If it can’t be done, please stop me while I’m in the beginning stages before I waste my money 😂! Here’s my question: can I use the Evo 8/9 oil filter housings on this older 7 bolt? I know you get a lot of comments. I hope you take the time to read this one. Thanks in advance and keep those videos coming!
Great stuffs Jafro!! Always excited with new videos but it kinda sorta bothers me that the audio is not the best. I know your voice over is great! The in camera audio is not the best, but hey it way better than some of these starting up channels. just a little constructive criticism. Please keep on doing what you do 👍👍👍👍
Is it the buzzing of the lights? Because I found a 60Hz filter than nukes that, but it makes me sound a bit nasal... and a bit digital if that makes any sense? But knowing where in the video vs. the problem is helpful. The shop is a big square concrete box and it does tend to resonate. Using a lavaliere mic might help with that...? Or perhaps anything other than a shotgun mic?
@@Jafromobile Its partly the buzzing and the reverberation from the walls. Also sometimes you would walk away from the camera and be outside of the mic pick up pattern. I really noticed it from 3:00 to about 4:40. I was just expecting spectacular audio from your videos and that the only reason I bring it up. Tom's Turbo Garage and yourself in my opinion always had/have spectacular audio quality.
I could tell the sound setup was different, but it's worth noting that the change did not bother me at all. Your time is the main constraint, so if a minor compromise in some other area saves you time, it's probably a net gain.
If audio becomes a problem, personally I'd rather record cheap audio on set as a reference, and voice-over in the edit suite. Bonus: I can play music on set, as long as I'm not recording ambient sounds that need to be in the final cut.
@@LeonBuilt Go to 13:04. 3 seconds later... that's when I found the 60Hz filter. It makes my voice thinner because apparently I have 60Hz overtones... but POOF, hum of the lights disappears. It's something I can use to fix the shop hum, but it doesn't fix all the reverb. Keep using the filter?
@@Jafromobile When I first hit that part of the video I thought my internet speed had fluctuated. I live in a rural part so speeds are not the best. Now that you mention it I do notice the dulling of sounds and the voice change. I would suggest omitting the 60htz filter. I can live with the humming instead of the dulling effect. Perhaps in the future a LED shop light upgrade. I would highly recommend the (Barrina LED Shop Light, 8FT 72W 9000LM 5000K,(Pack of 10) can be found on the Amazon) great upgrade from my own experience. Taylor ray has an awesome video about these lights. (First Upgrades to My New Shop! Huge Improvement! 13 mins in). This is one persons suggestions, please go about this issue according to your thoughts and the communities feedback. Thank you Jafro .
I have no use for the information in this series. I still watch it. Insanity.
Keep all polishing tools in a clean sealed environment. I don't know how many times I've had guys ask me to fix their polishing after they decide do go after something with a wheel, bonnet, what ever, that has been out in the open for years. They are packed with silica, metal oxides from other processes in the area. Personally unless it is getting plated. The hell with polishing. Lot of work for short term win, with a long term failure. I paint everything.
Should I use any chemicals or varnish on it after the process to prevent corosion?
Fascinating
Just curious, could you use vapor honing for some of the intermediate steps? With the setup I have, I'm able to get really nice results and bring out the fine details, but obviously not to the chrome-like finish you get to by the end.
Oh, BTW, I very rarely use more than 600 grit emery cloth or paper for prep even on sand-cast parts and 400 is often more than enough when starting with a hard wheel
Hi whats the name of the polishing kit
Jafro, I’ve got a bit of a silly question. What happens to the brilliant finish when you take the head to the machine shop and they wash it in their parts washer after machine work?
I though of you! I made a playlist. The first video in the playlist is me doing exactly what you just asked. You see... this ain't my first rodeo. Not only have I done it before, but I've rebuilt my other polished cylinder head twice and had to completely re-polish it. First video in the Polishing Aluminum playlist is my old G6K fresh out of the hot tank. ;)
Actually that's a good point. You could use something like a Dremel and a ball endmill. Maybe don't shoot for polished but instead make the character consistent, like engine turning.
What kind of machine shop issues are being faced?
Wow very shiny
I heard IT in there! 568a or b?
keep up the good work :) Are you doing the intake manifold?
Pretty freakin cool indeed.
About the protection.
Enough is never enough.
My dad got mild copper poisoning from cleaning old fireplace pot.
Weared long sleeves, gloves and two KN95 respirators, just the dust that got on his face made him sick 2 days straight.
A+ what serial was that Milwaukee ?
Printed metal foil label had the model and serial on it, wore off 20 years ago. Now it's a blank metal foil label. Believe me I wanted to scour the internet to find another one but came up blank just like that label. There's no molded model or serial numbers anywhere on it. I have the exact same question as you do!
@@Jafromobile I'm surprised they weren't stamping serials...ink seems weak-sauce for that era Milwaukee. Even my old 3/8ths junkie toy circa 80s I think was stamped..anyways.. I scoured ebay, it looks like the 5194 (5 amp) or 5196(11 amp?). The 52.. series are still being made it seems, China style, but there is 100% a difference between the USA made Milwaukees and the China versions. (For realz. Aint racism, just truism. Try out the old Hole Hawgs from the Wisconsin plant originals vs the newer China ones...)
Everything on ebay seems real overpriced so it seems like people are onto it :o If you can take high res pictures/give me dimensions of the shank, the collet, the length of grinder between the bit and the trigger, I can further scour the intertubes. I wonder if zee Germans have an equivalently good Fein secretly hidden away from the US market.. their 4.5 and 5" angle grinders cost around as much as the rat tail Makitas and last just as long.
Your cable looks like its gonna fray off. I'd pre-emptively replace them with a nice SJOOW or SOOW (oil resistant, water resistant) CSA approved @ 105c (125c is overkill) cable. Also replace the carbon brushes if you want.
I'd open that up though, and pre-emptively change the brushes. My mom (lol no joke, she's hardcore with tools) picked up a lot of tools from garage sales in the 90s, which were from the 70s and 80s era...just keep the brushes happy and I bet you'll get another 10 years outta it.
A+ A+ A+ Jafro 4eva
What is that smallest tool your using? Is that electric or air?
Have you considered connecting the harbor freight grinder to your air supply for heat dissipation? 😀
Might be worth swapping the Harbor Freight cord onto the Milwaukee, maybe even the brushes if they fit.
Excellent results Jafro!!! I’m here again 😅 trying not to talk about the forbidden path so I don’t get scolded like last time 😬 (wet vapor honing), but I really DO what your opinion......Given you’ve completed ALL the time intensive / foundational steps, do you PERSONALLY think that it could be beneficial as an additional / final step in getting uniform blending around some of the hard to reach corners and letters, WITHOUT messing up the finish you worked so hard to achieve currently??? I’m asking this because I’m doing a set of motorcycle cases / cylinder in basically the same way as you’ve outlined in the last 8-videos...
It'll do it! But one thing it will also do... it's gonna change the font.
In the video I mention the casting is very porous around the lettering. It's a lost wax and sand process. The detail work around the lettering tends to crumble when the molten aluminum hits it so grains around the letters break up slightly and leave the detail pitted. It's not severe enough to compromise the part, but it's rough enough that you can't get inside or between the letters smooth. You can definitely make it smooth-er with a vapor blaster, but to dig deep enough to take out that rough cast, you're going to change the font. It will round edges if you do it long enough to make it smooth-ish.
But I'm not being a defeatist. I'm being an acceptist. I accept there's no good way to make it perfect. Vapor blasting will help you smooth parts for polishing. The only thing it lacks in this whole process is the ability to plane the part flat. The techniques that plane a surface flat won't get the detail in the letters and a vapor blaster would. The vapor blaster will get all of that detail work accomplished, but it will round off the edges just like the black rouge will. It will do it before you start with the black or brown rouge which will round it further. I know vapor blasting is touted as a non-destructive process, but it's not. It's just really slow to "destroy" things compared to other types of media blasting. It's less-destructive, not non-destructive. Sometimes you have to destroy things, crack eggs to make an omelette kinda thing... even my manual methods will do that but once polished, these methods all create their own effect.
I mention in early videos the "arsenal of weaponry for polishing aluminum". Vapor blasters, media blasters, tumblers, and also everything I've demonstrated in my old school methods are all part of that arsenal. There are no wrong answers. Only different methods for conquering different kinds of shapes and problems. I suppose I wanted to demonstrate the sub-$100 method that's been around for over a century as the foundation of the process so that the one doing the job understands it and adapts other processes to their particular piece of work. Vapor blasters save time but they're out of reach for many people who want to start this, and my example demonstrates you can win trophies without it. That's the method that worked for me, and why I preferred to share it. You never made any sort of list or turned into any sort of problem child, lol! You always asked or suggested a valuable option. Happy Thanksgiving!
Chicago Electric - you get exactly what u pay for. 3 big angle grinders in 3 days. I will never disrespect my shop with that brand ever again.
Man does that look, nothing short of amazing though... What's the hour count up to? Grueling time spent for such a finish, an for this, we solute you!

Sure are lucky to have Harbor Freight at hand, even if their items are questionable (china made) Here in the UK there's no main shops that you can walk in and buy such items, has me wondering what people did prior to the internet.
Also a large flex shaft for a bench grinder would be ideal to use the 1/4 shank, i've been searching for one for a long time with no luck, the guys in India uses them when re-treading tyres.
They went to car meets that mailed out newsletters to learn how to do new things and see other people's work, and I suppose they bought $20 die grinders out of the trunk of cars not understanding that the seller would then go spend that money on crack. Seriously, I was so young and stupid. I don't know if it was stolen or not, but it's not even the item he was trying to sell me. He had a great hard-luck story that made me sad, I just wanted to help. I needed nothing he offered, I said "what about that?" and pointed at it. I didn't know how that worked. Naive. Gullible. Yes, Harbor Freight is much more convenient!
Additionally, if that exchange didn't happen, I might not have ended up with the right tool the first time I tried to do this, failed, and then quit without achieving any of my success because this tool was actually hundreds of dollars outside of my price range at the time. There was no harbor freight back when there was no internet. Tools used to cost a fortune when I was young because they were all made here in the US, and marked up a half-dozen times during distribution. But, they certainly were built well! Which begs the question... how big of an impact has harbor freight had on the young automotive hobbyist today that put all the formerly-expensive tools within reach? Or the internet that brings you the information you used to have to get by traveling to events to meet the people who do this kind of work to ask the questions. It's pretty cool that I can share all this with someone curious about it 3,540 miles away for $0.
Yes, so this whole process counting in years probably already and countless hours of work OR polishing machine with ball bearings vibrating every corner of that engine head ?
hey man , I want updates , updates and updates on this , all this and not see it installed , don't let us hanging
Loud and clear, dawg. 🤍 This blingy head is just one part of a complete car restoration. There are a whole lot of moving parts and a lot of different shops involved with all the different pieces of two cars' restorations. It takes time and a whole lot of $ to produce the results I'm about to unveil on both restorations. Many parts came back recently, and I've been working with the ones I have. I'm about to upload a video of over a hundred pieces rebuilt, restored, assembled, replaced that took a whole year to complete. My next video upload makes the car roll out, and it gets me the space I need for exactly what you want to see. I've got 1h15m of it voiced. Whenever I'm gone for a while in your feed, I'm about to drop something really epic!
Since i already have the machinery to make them, i haven't bought wheels in a long while. Whilst indeed some prices reflect the quality of the end product, they don't reflect the actual manufacturing price.
You roll your own wheels? Dude, that's badass!
and i bet ereybody this whole time was under choking out the side of a neck snooting, that this old cat and his dang hyundais werent what was the buisiness, while this man just flexed the 90s whoop there it is! the mans a true mr clean, sir don the one lord clout... freshed us up on all of us wannabes.
Lets be honest for 1 minute. My PT Cruiser, will never get this treatment, nor does it deserve it. However, I can not applaud the effort you have gone through to document this process any harder. This is the kind of content I would select for the "Knowledge Humans Possessed" In the alien museum erected on the charred remains of our civilization.
It's been a year already since the step one... Damn.
Yep! I know... while I did make 6 videos about this thing, I made 23 videos total between TH-cam and Patreon over this exact same stretch of time. The first one took me 3 months of non-stop work every day around my day job, no cameras, no editing, no instruction, just continuous non-stop work. I'm actually surprised that producing this along with 17 other videos that it didn't take me longer to do. Making a video about a thing usually takes 10 times longer to do than just doing it.
I have just finished restoring the engine for my Peugeot 205 Gti, an xu10j2te, with forged pistons and rods, with a disco potato and DTAfast management for more power.
Anywho i purposefully left my cylinder head completely full off white aluminum corrosion and impurities, simply to annoy people that polish their engines like this. Chrome won't get you home and all that.
I will never understand why people do this. So much work for basically no reason at all.
How to beat a dead horse vol. 1-1000
the letters look fine, kind of like the character but, now i'm curious how a jeweller would do it.
With dentist drills, teeny tiny tools, numerous tiny wheels and diamond paste. Not that I've done it. I've just never found the rotary tool I want. The one I'm looking for is a foot-pedal controlled antique with an articulating arm. My mom had one when I was a kid and it was incredible. Very comfortable but somewhat dangerous due to the 7 foot long external belt and pulley system making it just a little bit more fun. Put your hair away. It was a workhorse with tons of torque that could do everything detailed and heavy enough that it made it extremely steady. I'm not willing to use a Dremel for that level of detail. Modern dentist drills are quite a considerable investment. But I'm like you, I like the character.
@@Jafromobile we can always duct tape your arm back on and have you try out for soccer ⚽
do that in Belgium and they declare you crazy, really ! ! !
part of me wants to ask "why though?" but another part of me remembers I'm watching Jafromobile
lol pretty ballsy running those wheels so fast. Those eastwood buffs are apparently only meant for 2500rpm but electric die grinders are going at ~25000rpm. Good call on the safety gear! I might have to try it on some mold polishing. I only ever use a drill. Very slow... Kudos to the milwaukee for not dying. I killed my makita bearings running too large of a tool. Now i reserve that for burrs only. and sanding/cutting discs go on a pneumatic one now.
Oh, I know! I've actually always done it this way, though. That's precisely why I did mentioned it right along with the safety gear, and encouraged people to upgrade it. The wheels do blow up from this sometimes, but you do get more done faster like this. You should follow the recommendations for the most part, but there are circumstances where it helps you if you don't. If these were cutoff or grinding wheels, there's never an excuse for exceeding the RPMs. When polishing wheels blow up, it's more like a teddy bear exploded than being caught inside a meteor shower. It mostly just makes a big mess.
Great advice the smaller the tool the easier it is to get in tight spaces 🤣
Me at the start of this; "I'm gonna polish my timing covers and intake manifold"
Me 5 minutes into step one; "I'm gonna paint my timing covers"
What I'll actually do: Clean them with some brake cleaner, while appreciating your hard work instead
20:43 yup. Honestly, if you don't use those ppe you're not a professional, you're an amateur. A foolish one at that. Your product will be inferior and you will injure yourself whether you know it or not.
I would just grind those letters smooth. Don't need em.
