The cleaning guy appears to show a good aptitude for this line of work. I recommend he be promoted to the machine shop. Mind you mucking out pig sheds and scrubbing toilets is an honorable trade, but he's got a gift here!
We will keep that in mind! lol
Yeah, I got that same feeling...
Yea, seems to have a knack for machine work.
Definitely got a talent for both cleaning and machining! 👍🏻
Dont praise him too much or he will want a raise.....
On the subject of balancing, as a power generation engineer, we had a gas turbine generator that had developed a severe vibration. Rather than spend over $100,000 to remove the generator and transport it to the manufacturer’s repair facility, we brought in precision vibration analysis equipment and identified the direction and magnitude of the displacement.
A single 1/4” flat washer was added to a balancing post on the rotor which was peened over to hold it in place. This solved the vibration and saved $100,000 plus weeks of downtime.
One single hardware store washer!
Amazing how simple the solution to a complex problem can be.
I love seeing a master doing what so many never even knew about. Thank you for all the memories.
Jim you are a master craftsman. I was an apprentice mechanic in the late sixties. We used to take our machining work to a couple of " old boys" in a workshop full of machines, probably pre-war, or war surplus. they always did a perfect job. later I encoutered newer shops with newer machines, but you didnt get the quality.
Thank you for showing us your workmanship. All the best to you and Nic, from here in the UK.
Unbelievable education! So much skill, patience, and attention to detail!
I'm an electrical engineer, so am really interested watching you work your magic on a crank. I don't know if you have a degree or certificate in your line of work, but you COULD be a great teacher, & teachers are indispensable, especially in our 'throw away' society now. ALWAYS enjoy watching you, guys, but THIS video just shows how knowledgeable you are, & how much money you charge is worth every cent! Thnx You were always better than the "cleaning boy" we last saw you as:)
I 💯 agree.
I just watched a video about the restoration shop at the Pensacola Air Museum... The machinery in the machine shop was to die for.. I was thinking the same as you, are there young people coming up being taught how to use these machines????
Let’s change that to “is” a great teacher. Now on TH-cam.
He’s a degreed mechanical engineer
Engine repair machine shops are a dying breed. Performance engines and large truck diesels are what keeps most of them going these days. Modern vehicles rarely have engines rebuilt even when they die. A secondhand unit is usually the repair option for that situation. Repair time is the main factor involved here. The more labor involved the higher the cost. it used to be that parts made up the majority of cost hence repair was the cheaper option.
Been a long time since I hung out at “Mike’s” when I was a lot younger. I refreshed my learning curve and seen some new balancing “tools” ! Thank You Men, nice quiet way to spend Mother’s Day afternoon. (Hey MaMa got a nap too 😃👍)
Cleaning guy, you are definitely from the old school. I believe you're the 1st person I've seen shut down a torch properly. Well done sir.
Really enjoyed this comprehensive format. Amazing how much goes into these engine rebuilds 😊
Every time I watch one of your videos it makes me wish I had found a local shop like you guys to go the extra mile instead of slapping it back together with fresh bearings and calling it a day. Awesome work and attention to detail!
As a military vehicle owner and enthusiast, it's almost comical to see how much care and precision you're putting into this old engine. I love watching the machine work but it's going to end up absolutely light years better than it ever was, even brand new. This is going to be the most precision F-Head ever!
Great video, the cleaning guy seems to have a knack for this machine work. Seriously though, true expert and great explanation of what you are doing each step of the way. My only regret is that you are too far from my area to give you any business. Both you and Nickolaus have a great work ethic and always a commitment to quality. I truly appreciate your candid discussion of being inside specs, demonstrating that nothing is ever "perfect". You always demonstrate a desire to get the end product as perfect as possible for your customer. Well Done!!!
So educational to see a young guy workind down to a couple tenths that far between centers. He has a bright future ahead!
Stoked to watch some more old school stuff. If I ever need machine work, I'm bringing it to you. You guys care about quality.
Thats a fact!
Every episode there are always a couple pieces of experiential wisdom that the cleaning guy imparts.
Real pleasure to watch a craftsman at work.Hopefully the younger generation will one day be as good.
JAMS,
You guys are very talented.
While watching I wonder the engineering that went into design, development of the machines you use. Very interesting and informative.
It would be nice to see the engines running after assembly. Thanks, Boe
Thanks for sharing yalls talents and adventures. Ole Pops does a good job of explaining not just what he is doing but thw thought peocess behind why he would do it that way. Great job.
Also the camera work and editing were spot on.
I was a mechanic for two summers in (75-76) High School and a Tank mechanic in the Army for 3 years. I studied all things automotive. Came across the term Balanced and Blueprinted I found out what Blueprinted is reading Smokey Yunick's book. But I never knew what balanced entailed until now. Thanks for the video.
Love watching the balancing act.. Ain't cheating..it's working SMART!!
THANK YOU for sharing your time with us!!
You have created an absolute treasure trove in this YT channel! This video is, perhaps, the exemplar for clear, precise, and correct information for proper engine building.
I could watch you guys rebuild engines all day, something so satisfying about building something nicely.
Best Sunday morning television ever right here. I tell ya, that cleaning guy has some chops. It's like he's done this stuff a time or two.. 🤔 Also good to hear the culprit with the wrist pin getting into the cylinder wall.👌
"Always think of the next guy, because the next guy may be you... " :)
Jim, your experience and understanding ,along with your articulation is truly helpful for those of us with substantially less experience. Thank you very much! Cheers
I can’t get enough of these videos. Thanks for taking the time to make them and teaching us along the way. Fascinating.
I love it when the cleaning guy goes solo, he's a great teacher!
That crank grinder is a beautiful machine. I’m glad to see the cleaning guy takes good care of it.
He does keep it clean!
Very nice Jim! First time I have this process. I used to check our Allison C28 Turbine engines after OH and build up in our helicopters. Vibration is a component life ending happening. The manuafacture would not listen that they had a vibration until we brought vibration specialists in th the equation. You did a very nice job explaining and showing the process.
The last crank you checked out wouldn't have a ring even if it was new, because that crank is cast and not forged. I've always been told that the ringing test works on forged cranks and it's easy to tell them apart because a cast crank will have a very thin line on the rod throws from the molds used and a forged crank has a fairly wide grinding line where the extra material from the hammer forging has been removed. Somehow the first crank is a forged crank and the second one is a cast version. Possibly the earlier military jeeps used a forged crank and the later civilian units would use the cheaper cast ones.
What a pleasure to watch a Master at work.
Learning so much! Thank you and please continue with the Willys F 134, certainly enjoying this series!
Another excellent episode of The Cleaning Guy in Action!! Way to go, Jim and Nick!! Shops such as yours are becoming scarce and the two of you are doing a great service!
I'm happy I've found your channel, I have some machining experience, but this is fun to watch... Thank you for allowing me to be able to watch... And the Cleaning Guy definatly needs a partial raise...
What a Master on this engine! The 75 horses will have a smooth run now!
The 3 machinist I know all shake like that. I think it's from a couple things. Working all the time, using the old machines, small tedious work. I look at it as a good machinist with lots and lots of experience. Love watching the videos. Keep them coming.
10:30 pm, Great skill with the technical work, I thoroughly enjoy viewing your videos, looking forward to the next episode of this series. Thank you 😊
That is a heck of a lot of work. And there is more to go. This is coming out far better than they would have done at the Willy's factory. Good job.
You and Bob Ross have a soothing way of explaining what takes yrs to master. I could watch for hrs!❤
Really enjoy watching the cleaning guy do his thing with old engines.
Thank you the education you give is priceless. I have an engine builder just around the corner from me and I asked him if he needed help and I would love to work for him, but still no luck.
Picky. Picky. Picky. But, if I were paying for the work, I'd pay it in a heartbeat. Precision. Precision. Precision. That is the motto of a great shop.
Always love seeing the crank grinder in use. Such a cool piece of machinery.
Thanks for the detailed explanation of the steps &process ! You are VERY thorough! I think there’s not many shops of this quality left in this country !
Great video and Great work! Thanks for letting us watch!
These guys do excellent work, I know because I do some of the same type work ! They don't hide anything, most machnist will hide tenths of and inch and claim they landed right on measurement. 1 to 2 tenths of and inch is some pretty good tolerances! These guys are very good at what they do.
Thank you Jim , just one more great learning experience for me. Nothing better than watching you preform your magic on motors.
Abracadabra
This guy must be new.... it looks like he's only done this a few thousand times. It's pretty impressive to see him apply so many little tricks. A lot of time was invested for him to do that so quickly.
Cleaning guy is a national treasure!.....Sure wish you were closer to east coast. Got some EJ 25 heads that need him.
Thank y'all for doing these shows, even though there are some real a-holes that would comment.
Awesome machinery. The knowledge to use it all is even more impressive.
Usually a ring-the-bell test is done suspended to prevent damping from the support surface as well as the hand used to stabilize the crank.
Love watching a master at work, the amount of equipment and knowledge in their use and goals, would love to use your shop for work and would be honored to work under your knowledge with a flair of humor thrown in 😊
This was an interesting video to watch. The owner of this engine is going to be very happy with all the thorough care you have taken so far. I am looking forward to seeing the next phase in getting this engine together.
so nice to see the great detail you take in all the work you do ,,, AMAZING STUFF GUY,S
The depth of your knowledge is unbelievable ❤ thanks you for the time u spent making this video .❤
You answered my question before I asked. When you were grinding the rod and cap ends I was thinking that will make the hole oblong. Glad I waited to comment.
A lot of work for an F Head motor. I doubt many would have balanced the entire rotating assembly like that, and if they didn't, I doubt the owner would ever notice via the operation of the engine. Nice work. I appreciate the attention to detail.
You're son-in-law is doing a great job with the camera. I bet he's a good student as well!
The bolt on counter weights will dampen the ring of the crank.
I just wish you were closer to me, I would give you all my machine work.
All the good shops in so cal have closed up.
It's very refreshing watching professionals work.
This is excellent insight into the mission of doing good engine engineering. Promote the cleaning guy!!!
Love your channel. i used to work on Cummins and Detroit Diesels in the 1980's as a school bus mechanic in the Sierras in California, so watching your work is very interesting to me. My Step-granddaughter is named Amelia Pelz, Her Grandfather is Joe Pelz, who has a dairy very close to your location. When we visited my step-daughter when she lived there in 2001, I bet we drove right by your shop. Small world. Keep up the good work.
Yes, it is a small world. I know Joe. Too funny.
You guys are so amazing! Real American precision craftsmen!!
As an auto mechanic apprentice [late '60's] I learned that forged cranks ring clear & crisp, while forged [correction, Cast cranks] cranks ring kinda flat. And that's how it's been for all the engines that I have overhauled or rebuilt over the last 55 years or more. Your used Willys crank looks like a casting.
I think you wrote "forged" on both, which one rings clear and which one rings flat?
The Willys is actually a forged crank but the bolt on counterweights seem to dampen the sound.
That and weights are bolted on that would just kill the vibrations of the ring.
Yes, I thought that the replacement crank might be cast iron because it has a much narrower parting line than the original. The difference in "ring" might just be caused by the bolt on counterweights
@@JAMSIONLINE THAT is what I said when you did it. The bolted weights will not ring.
Use it as a post for a letterbox.
I have seen a crank from a large engine used for the post and a connecting rod and piston with a cylinder sleeve used for the letterbox
I'm Learning from a PhD in Machining! Just so impressive and great job!
The attention to detail and explanations of why the details are important make this channel simply amazing!
I’m amazed. I wish you did the work on my first car (1937 Plymouth). Keep up the great work 😊
Man that crankshaft grinder looks like a blast
I have a friend that's a ex navy machinest. built a race car from the ground up. this guy has serious skills.
Quality hour and a half. Felt like 10 minutes. Such a great watch. Thank you.
I'm glad you show every step so people have an idea of how much time effort and knowledge it takes just to get ONE of many many tasks involved in building a motor correctly.
He has so much old school knowledge combined with modern, its crazy. True craftsman and very very rare he is. Awesome to watch!
9:40
look at the cleaning guy using the flashlight on his hand held surveillance device 👏
Those little F head Hurricanes when all was well and in good condition ran like a top already... I can imagine this one will have to be visably looked at to see if it's running. It's gonna be smooth like a sewing machine after "The Cleaning Guy" gets done.. Love the work as always. No doubt in my mind that customers get what they pay for and more at Jim's Automotive Machine Shop... I need to find an excuse to drive to CO and bring you guys a little 4cyl gas Farmall and a Cat C7...
That's going to be the best running jeep engine ever!
I was thinking about all the specialty equipment you use to accomplish the machining. Impressive equipment…..but useless unless you have someone knowledgeable enough to use it. I applaud you my good sir.
Wouldn’t dream of making fun of something you can’t help,you’re a clever man with only skills I could dream of having.keep it up 👍
Great content, and a great shop! I've heard cranks ring too. Though this one has bolt on counterweights which may not ring, and being clamped in copper vise. Like a tuning fork, I think it needs to be freestanding or hanging. It's really good, JAMSI is making these videos. As cars become disposable shops doing this work ar getting harder to find. Someday someone will be trying to do this work with nobody to show them, and this will bail them out.
You remind me so much of my deceased father-in-law. He was a machinist and had all the equipment in his garage. He would be thrilled at the newer computerized equipment to make things much closer.
Been watching for a while, now. This video was just fun!
46:47 I like those custom copper vice-jaw protectors.
Coming along nicely. I wish I could follow along and learn all this in the shop with a legend like Jim, the cleaning guy! 👍🏻👌🏻🛠️🔧📏
Great video. Not everybody does the crank grinding. Fierce machine and operator.
One of the best descriptions and view of what is being done as you go
So amazing to have these F Head videos. Just got my F Head 61 Willys running.
Nice! Been wanting to do one on the channel for a while.
29:34 By the side of the belt sander you can see how time progresses. If you carry out this "breaking edges" often enough and use the side of the unit to parallel out the rods and caps - the paint is gone in that area. Thanks for showing !
Another interesting and informative video Jim. Your work is very precise. @1:04:23 I like your dog.
Best video I ever saw you produce. WOW nice! /thank you so much!
Cleaning guy did a great job. So is the camera guy.
For a second life, I've seen many crankshafts converted to mailbox posts.
Excellent long video; I've always wanted to know what went into engine balancing step by step; Thanks for the clarity and detail of your explanations.
Wow, what a great video! I wish I could be an apprentice in a shop like this. Learned so much!
Never seen crankshaft work being done. Very interesting.
Amazing machine work. This guy has probably forgotten more than most machinists know.
Thanks again Jim!
Thanks for watching!!
It was nice visiting with you last week.
Would love to see this running in the end,, this is incredible stuff!!!!!
Lastly, thats a cast crank, it has a small parting line.....forged cranks have a quite WIDE parting line.....cast is fine for low rpm....over 5500, that where it gets dicey!!...GOD SPEED sir, LOVE ur chanel!!
thank you for this video. And the cleaing guy sure knows what he is doing lol damn it this was both fun and educational and I fell for it
thanks very much gents, very much appreciate the time you take to make these. 1.5 hours of pure education, level of detail and info is very well balanced and the insight you bring is invaluable for shed and professional engineers old and new. Perfect way to spend a Monday May day evening Many thanks guys!
So cool watching an old school pro!! Thanks for the info!!
