- I machined a set of aluminum pulleys to be fitted onto the 20mm shafts from the previous video. Lot's of basic manual lathe and mill work, including some push broaching for the 6mm internal keyway.

Man I sure like the way you do not get in a hurry and clean all your tools and return them to their proper places
That’s just common sense
It's nice to see people take pride in their work, which includes their tools
@@Dreddip yes sir
I’m happy you lied to us and showed the drilling and tapping!
Dead nuts:
Used in many trades to mean 'spot on', or absolutely accurate. It originates from the times when machinists machines were set with a set of nuts, on a fine threaded screw inside the machine which controlled it's movements to and froe. The nut would be set at absolute zero, or the stop, or limit of the machine. When the nut was tightened, and the zero set, it would be considered a dead nut.
Hey Adam I'd like to thank you for the inspiration you and other content creators have given me. I'm 24 and I have 2 manual lathes a manual mill and just got my first Cnc. And everything I've learned has been from TH-cam.
It is refreshing to hear people so young already devoted to becoming a machinist. Me? 50+ years machinist and toolmaker. If I can recommend something it would be to read the Machinist's bedside Reader series by Guy Lautard.
@@eboneezeradams1821 thanks man I appreciate it it's awesome being in a community that like to help each other and give advice so much.
The new lathe is cool, and quiet but man, I love that old press. It clunks, it clicks, it rattles and just keeps on keeping on.
I love the fact that you show us the repetitious drilling and tapping. I really enjoy seeing you drilling holes and tapping them.
😅
These videos are becoming more and more simple like high school shop class projects.
i'm sure he'll start makin some big shafts again in the future like the good ol days; he has that american pacemaker after all. he also has that giant planer on the way. at least he finished the parts. there's worse examples with other youtubers where somehow a 4-operation part is turned into a 2-part video
I have descent content, not the greatest video but wish I could grow my channel to his numbers.
@@thebeardedgunsmith9177 subbed!
@Steven Dupre….says the guy with no content of his own.
@@thebeardedgunsmith9177 looking you up now
aluminum is such a pretty material. Seeing it lathed is one of my favorite things.... Brass a close second!
Simple yet involved.
Thank you Abom !
Metric, DROs, New Machines........man I have most diffinately been under a rock..lol...great video as always Adam.
Shouldn't metric aluminum be aluminium?
I’m sure Her Majesty would not have minded the change to her English. Rest in Peace your Majesty, Long Live the King
It's also 18.82 on the zed.
It really varies with the alloy - 6082 is aluminium, and 6061 is aluminum
Simple machine work is fun to watch. Enjoyed the show.
Adam..have you seen jim automotive machine shop recent video..?about a jaguar engine block..he mention your name in his video..he said..he learn how to use precision tools by watching your videos when he's in college..you sure inspired a lot of young man all around the world..
I see comments about crown and chamfering but I think that was from old belts wearing on the old part over years of use. Thanks for the video. While I am no machinist but I have worked around some in the past and this gives me a greater understanding when i do my DYI projects.
Excellent work,Adam.Thank you.
Really enjoy the step by step explanations. Time to go make some scrap!
I have learned so much from your channel. Thank you, sir!
VERY CLEAN JOB, I'M NOT SUPRISED. THANKS FOR SHARING ADAM
Is that flat belt going to be happy with no crown in the pulley? The old pulley has that ridge down the center which provides a rudimentary crown.
If the belt is not too long, you can get away with one crowned pulley and one pulley without crown...
@@Henning_S.
I've worked in the printing industry since 1996...specifically bindery machinery. There is a LOT of flat belt stuff going on there when in comes to moving cut sheets around for folding, gathering, punching, and putting that staple in the girl's belly-button. Every run of belt is on crowned pullies... Just like back in the days of stream-powered line shafts in factories and traction engines in the fields.
Thinking about it over the last few days, though, I'm sure that Adam contacted his customer about turning those pullies flat instead of duplicating the original, with it's raised center rib. He's far from a dumb guy, very careful about double-checking stuff, and he's been around flat belt equipment... There may be a video from one of his shop tours that goes into it.
Besides that, he's got a CNC lathe that would've made short work of creating a perfectly crowned pulley.
@@Bluswede yes, of course you usually use only crowned pulleys, I'm just saying that a short belt will also work if one of the pulleys is not crowned ...
@@Henning_S.
Agreed.
It always amazed me that a belt would want to 'climb the hill' to ride atop the crown. It's so counterintuitive, but when you put Physics on its tail it makes perfect sense. It's as if the creator had it in the plan that people would go through a period where flat belts would run everything and that precise alignment would be as elusive as mermaids' kisses!
The last shop i worked at i used to broach right in the lathe using the tail stock to push the broach through before pulling the part out.
What a breath of fresh air. After Ian, pray you are all good. We are located in Englewood Florida. We are on the right side of the storm. We are all good. House is ok but the highest gust was 208 mph. Everything can be repaired, loosing a life, that can never be replaced. Thanks for all you share. I feel blessed as being a small part of the Abom family. Thanks.
Lovely quiet lathe
Another great video Adam, thanks for sharing. Hope you folks are having a nice weekend.
👍👍👍👍😃😃😃😃👏👏👏👏
Awesome job
Great video 👍 and a dro is a must in 2022 in my world 😁 you should really consider mounting it on the carriage so its closer/in reach. I've used a Victor with it mounted as yours for 15 years, and when we mounted a new it were put on the carriage. Soooo much better. All our machines are now like this. And especially important on the ones with long beds 😊
My 'new' Microweily ty2500 has also the dro mounted like this. And it's very similar to yours, size-vise. Also it's nice to not have to reach over the spindle/chuck constantly 😊
Another great job, all the very best from U.K.
I always enjoy your videos thanks for al them
You are loving that new toy, long may it work for you!
Carboloy used to make a TPUX aluminum insert that gave a great finish ,also good for opening packages with it's razor sharp edge.
Nice work, love to see it!
Always good. Touches off Saturday of TH-cam.
Glad you approve of my "eyeball the drill bit sticking out parallel with the vise" method.
Those little JBL bluetooth speakers are fantastic. The next size up from that one you have on the lathe is crazy good for the price.
Hey Adam, I'm certain it was just an "on the fly" dialog miss-speak but in case an onlooking newb was watching, 1/8" = 0.125" rather than 0.12" as stated. That PM lathe is looking like it passes the Abom standards with a resounding thumbs up!!!
Hope all is well after the Storm... !!
Outstanding video, great work! Thanks for sharing. :o)
Adam, just looking close at the sample pulley. You said it was for a flat belt, isn't there a bit of a crown toward the center to help in belt tracking? If you look closely you will see a raised dimeter change in the center, l think this is to aid in belt tracking. (Just a thought) Thanks for sharing.
that's what I was thinking too
I also noticed a crown, probably not needed though because the 'walls' of the pulley capture the belt?
I'm hoping Adam mic'd the edge and center and confirmed no crown was present. I would worry that a flat belt would walk over to one side and either tear itself up riding the flange, or hop the flange and run off.
As others have said, crowning isnt necessary on flanged pulleys. Maybe the person who fabricated the originals wasnt aware of this. All purchasable flanged pulleys of this size range only come with parallel journals.
Nice work Adam. The Arbor, or lack thereof is the problem with two shops. You need of two of the fundamental equipment, one for each shop. Thanks for sharing.
That electric press is perfect for broaching.
Great job Bro...... as, Always !
You say those pulleys are for flat belts. Shouldn't they have a slight crown to keep the belt tracking near the middle? The old pulley looks like it has shinny strip from the wear, as if it is crowned in this way.
Crowning isnt necessary on "flanged" type pulleys, particularly on such narrow belts.
@@keithweathersbee1 What are you talking about? He made the pulleys to match his sample. He doesnt make squat off these little jobs unless there is a youtube video to go with it, so why would he half-ass it anyway? You just called the dude out for poor quality work over something that doesnt exist (crowned flat belt pulleys under 3 inch O.D.). Thats some real dirtbag behavior.
Set screw over the key means a shorter screw (less thread depth). It also concentrates more stresses, not that that should be an issue with industrial parts.
Wow, I don't think you could've chosen the speed on that parting tool any better! There was no flex at all when machining that groove at all. Dang, nicely done!
An interesting new video about our trade. Every MACHINIST Should Visit This PLACE! | American Precision Museum Tour Pt 1
Watching Adam using metric is a little bit strange but then i start to feel how much he's taking of for each cut on the lathe. I'm not used to imperial, specially with all the fractional sizes.
Have noticed that many machinists do the under an inch stuff all in thousands and bypass the fractions stuff.
Just watched a TH-cam video about broaching from Edge Precision and that guy is a genius on his CNC. Would be interesting to see you do the broach on your CNC😊
Muy buen trabajo maestro 👍 bendiciones campeón
I love watching a drill and tap opp!
Thanks for sharing
Very quiet lathe!
When he said he wasn't going to record the drilling and tapping I knew he was going to show it anyway
Have you ever thought about doing a video on how to price out a job? Love the channel!!
I think I saw some very nice CNC blanks for what look like the handles to hold Stanley Knife blades (Craft knife blades) in the background on your bench.
Now you have to get a press for the new shop. I don't know about you but I like getting new tools. Lol
I thought the original part had a convex surface for the belt? Hopefully the belt doesn't walk off these :X
Or wear itself to shreds riding on one of the flanges.
I was thinking the same thing! The original clearly has a convex shape that got lost along the way...
Adam:have you done a collaboration with This old Tony before...I see you pop up once in a while in his videos 🤔.Would like to see one maybe perhaps
I would just like to see this old Tony put out a video on a regular basis
@@danielnorman8595 Daniel
Yes I would be happy to see more content also! He's kinda a AvE, in a way with his shananigans😁🤣🤣
@@MHolt3573 my apologies I didn't know
That 2nd one goes by fast, nice
it must be an optical illusion; on the original part it looks like the base of the pulley is crowned to better handle a flat belt.
There is an undercut on either side of the belt sheave that Adam did not copy over. I couldn't tell if there was any crowning of the sheave.
Adam must have so much patience to create such beautiful parts. All of the cuts are sped up for the video but for Adam each cut would take minutes rather than seconds.
Nice machine
Hey Adam Jim's Automotive Machine Shop gave you a shout out on their latest video
Super nice shop fan you have. That one on wheels. I want one. It’s a BIG ASS FAN.
The original pulleys had a larger diameter section in the centre to act as a crown. Any reason for leaving that off the new ones?
In flat belt drives only one pulley needs to be crowned for the belt to run true. The drive pulley is usually crowned and the other left flat.
Adam that would have been a good project to do on the cnc!
I see you like to keep them fingers playing with sharp tool edges - the broach after getting cut by the drill bit ;)
You know if you don't have a broach/press you can "broach" the keyways by using HSS bars the width of the keyway on the lathe to shave it like a shaper. I did this to machine a key way into a change gear for the victor lathe (mine used timing belts instead of gears).
don't the pulleys need a slight crown to keep the belt centered?
This is what I am wondering about...
Yes these need a crown in the flat bottom to run correctly
I like a lot you shop
Looked like the sample had a crown. Is there a reason not to duplicate the crown? Thanks for the vids. I always pick up something new.
21:45 - If it looks straight, it is straight. That's some Jimmy Diresta stuff goin on there.
ah yes…a good cigar, a dram of rum and a welcome video from Abom79
Thought you had a step up in the middle on the old piece.
Great video amigo!! Loved the facing and turning chips. What insert were you using?
I do see you changed to metric on the DRO. Nice job on the pulleys.
the older pulley looked like it was crowned for a flat belt? did you leave that off for a reason?
He'll never tell.
@@Peter_Riis_DK Looking at the shaft assembly, mt guess is that these pulleys are back-tension pulleys, also, being flanged, they dont require crowning.
@@3-body-problem
Looking at the title, my guess is that these pulleys are drive pulleys - and looking at the original they seem to require crowning. 😁
Nice job Adam are you going to get a slotting attachment for the new Mill . JM
Just get a 20 ton press from harbor freight. They have an electric hydraulic jack you can get for it. Mine has done everything I’ve asked of it.
Gee, since it was a simple part, I would have guessed you would use the CNC Lathe for practice.
always a pleasure to watch you make stuff but isn't this one a bit of a missed opportunity to model in CAD and run the part from your CNC lathe?
I don’t think he’s there yet and it seems like this job was somewhat of a rush.
Hope you and yours are all well after Ian,
New brand of drill bits - bleed & feed - lol
What do you use for cutting oil? I need to get some, I like the way the stuff you use performs
“As usual, I lied to you.” 😆
So how good does blood work as a cutting fluid?
You don't have a Dake press in your new shop?!!
Is that even legal?
I'm sure it's on his shopping list.
If cutting tools ain’t sharp they won’t cut!
I’ve always try to never unnecessarily fiddle the tools or work with my fingers! Even light weight swarf can cut a finger tendon!OUCH one’s fingers are for use on delicate parts only! Used a swarf hook & brush or pump oil can for coolant and use barrier cream. Ps. I’ve still a full set of digits at 70!
Adam this is a curiosity question. By you putting the screw over the key I noticed that actually you are making the "thickness" of the material where the screw is located substantially thinner and weaker considering this is aluminum, in other words, to me it seems there is a strong possibility the threads will strip quite easily. Would be different is this pulley was made of a harder material such as steel or even brass . What do you think?
going to be difficult to get that analog feel on your new shop press at the "main" shop.
Hey, where did you get the mini flashlight that you use while boring out
I keep a bottle of super glue (C/A) at work just for fixing cuts on my fingers. Keeps it from dripping on paperwork.
You know CA glue was invented as a field medicine for small cuts? That's why it's so often better at gluing your fingers together than your project.
@@Kruglord it's been used in field medicine but wasn't invented as such.
Адам упорно работает в футболке! Инспектору по ТБ надо выговор выписать. (смеюсь)
Он его давно уволил! А может, и не нанимал вообще, бездельника )))
Впрочем, судя по двухметровому вентилятору за спиной, ему и в футболке жарко.
Would have been a nice training object for the CNC
Yeah, would definitely be a good little project for the NC lathe
Yes and would have been easy to make a crowned belt surface on the pulleys if needed with CNC.
What was the issue with the original parts??? From lil I saw they looked fine.
عمل جميل
I want this machine hehe
What brand is the gooseneck flashlight that is seen in the video when you bore the inner diameter?
The key prevents rotational movement of the pulley on the shaft. So the purpose of the set screws may be to prevent axial movement of the pulley on the shaft. If that's the case, positioning one of the set screws over the key might not be a good idea (since the key may slide axially).
One setscrew prevents the key from moving and the other positions the part on the shaft. Standard practice is to place the setscrews 90 degrees apart.
@@ellieprice363 Fair enough. Maybe the original pulley was designed for a Woodruff key (which would be captive and not require a setscrew to clamp it in place).
@@chrisarmstrong8198 With s woodruff you still need two setscrews. One over the key to keep it from wiggling and the other at 90 degrees
@@ellieprice363 A properly fitted Woodruff key is well-constrained. A setscrew seems unnecessary.
@@chrisarmstrong8198 But that’s the way it’s done in industry.
What aluminum alloy and temper did you use, Adam? 6061-T6X might be the most common but 2024-T351, 7075-T6X and others are possible choices with more strength.
Awesome videos! Cool I'm one of the first comments!
Wow that lathe is quiet.
