Best quote of the day, "There is enough needle movement to know I am actually measuring." Attention to minute details and targeting extremely small tolerances is impressive for cheap help. :-)

The cleaning guy sure knows a lot about engines. We need more cleaning guys just like him. Love the precision work for sure.

[@craigcode7103]

I am totally impressed with how clean your shop is because every time I see your cleaning guy he's wasting his time grinding cranks and decking heads to perfection.😁

[@MikeHarris1984]

Also, one thing I learned that was etched in my head from my old auto shop teacher in highschool, who actually looked alot like the cleaning guy here, same personality too. Amazing book of information. But he pushed that a crank is designed to be supported in the main bearings. And storing it laying down WILL bend it under its own weight And never ever ever ever store the crank laying down. The shop had crank slots like win glass holders under one of the long stainless steel tables, to slide the cranks in and they hang from the end. Always spread white lithium grease and wrap in a bag and store slotted hanging. Even laying down for a few hours, the crank can bend itself ever so slightly you probably could put back in and hold it and allow it to come down, but if it's bent when you torque everything down, you risk rolling a main bearing. I loved soaking in knowledge and always wanted to do machine work, but I didn't know anyone to be able to learn under. But now I'm a senior lead IT security architect for a fortune 500 financial firm working in an Air conditioned office putting together reports, power points, presentations to the CISO, and building our the latest security platforms... Just doing the same clockwork activities day in day out .. My machinest dreams set sail long ago :(. Here I sit sad and possible talent wasted... if any kid shows interest in doing this, be sure to invite him in and spark that little machinest in them to follow. :). My grandson, he's 11 months and I'm going to push to spark his interest in electrical engineering, or mechanical or something. And be something other then this new generation of pansies lol. ...ouch, my feelers are hurt by your opinion on something that has nothing to do with me, but I'm going to complain until someone listens. Lol

[@stevenbelue5496]

Very controversial subject about crank storage positions and I've always had a disbelief that a forged crank or any crank could relax or move permanently under its own weight when it doesn't move in its intended application with all the forces, stresses, heat being applied. I haven't seen any proof from having cranks turned after being throwed around and laying every which of way. But I still like to stand them up or hang vertical. Which if you think about it, hanging or standing could distort it just the same because the main centerline is not a continuous straight line of material so its not really supported much better.

[@thenumber8llc]

This is so awesome to watch, very precise! It's so neat to see someone still taking pride in their work!

[@michaelweiland6751]

You 2 are fantastic! You guys really pay attention to detail where it counts and have very honest insights. I would love to have you guys do an engine for me one day.

[@stevenm3141]

It's amazing out of all the shop videos I've seen many of the machines are older rather new. In that, it's the older machines that are making the difference for a better outcome! This includes the people who maintain and operate them! Their knowledge is invaluable and worthy of a timely periodic raise to keep their interests fresh.

[@edwatts9890]

I sometimes work with my sons, and they are often surprised by the number of tips and tricks I have collected over seven decades. I really enjoy watching. Thank you for sharing your time and talents.

[@jeffa4920]

For all of the great content you've produced, this one on Crank grinding is my new favorite. Watched it from beginning to end. So informative and the Cleaning Guy got to show case his talent. I wish a had pursued a career as machinist but life didn't work out that way. You're channel has provided answers to so many questions I've had over the years. I really appreciate your decision making process and that you share it with us. Keep up the great work. Be prepared, I have a feeling you're going to be inundated with brooms and dust pans from your fans. God bless.

[@benholt1728]

This is what it looks to do it right, not because it’s completely necessary, but because you are a true craftsman. The world needs people who bring this capability and consciousness to their endeavors. Thank you for sharing these videos!

[@Calango741]

This was my favorite of all of your videos that I have watched so far. I love seeing things done as reasonably close to perfect as possible.

[@needsaride15126]

Your channel by far and this video in particular. Is without a doubt the best automotive machine shop channel on the internet. Your explanations of procedures and information provided to the viewer. Your strive towards the best possible outcome on your work. Plus the back and forth banter between father and son. Thank you for your great channel and for sharing such good videos. Wishing you the best in the future.

[@tdkrei]

Your knowledge and experience is absolutely superior to some othef engine maching shop I've known. Great workmanship and I trust you are passing on that knowledge to your offspring. Keep on smiling.

[@raffly4449]

This level of precision is mind boggling !! Amazing !!

[@brewinfusedyeti3798]

This channel is awesome. All the technical talk brings me back to when I built my first motor and how much time I spent researching and trying to learn.

[@cheesecakehunk7932]

I ground crankshafts from 1985 till 2003 for a production engine rebuild shop. We worked 12 hours four days a week our goal was 35 shafts a day. But that was 35 chevys then 35 fords, dodges, etc. They had other crank grinders that cut one shaft at a time. I only did production. Watching y’all brings back a lot of memories.

[@roota81]

Watching the cleaning guys hands operate the grinding machine without looking at anything else but the dial just shows how many hours he's done cleaning on that machine alone😆 G'day from Brisbane Australia gentlemen 🇦🇺

[@herrjanssen8531]

It's so impressive to watch and listen to you both do all this machining and assembly work with such impressive accuracy and attention to the smallest detail! Even though I have a technical background, I learn quite a bit from each and every episode. Since I'm a German who has to look up certain terms from time to time, it's a bit more complicated, but I enjoy every video. Keep up the good work producing videos like this and celebrating true craftsmanship.

[@lynchygt233]

I can’t get my head around just how time consuming a built like this is! Amazing.

[@danlynch6194]

Impressive work. Thank you for explaining the grinding process.

[@bad406camaro]

I can remember doing SBC and ford Stroker crankshafts (400m to Windsor stroker) When doing the rod I was taught to leave 2 tenths on the first plunge and sweep after the second plunge. I don't remember the wheel width as it was over 35 years ago. But in a production setting one extra plunge on 4 journals per crank makes a difference at the end of day count. I love the relaxed pace and attention to detail on performance builds in your shop. Please continue the "Proving of Points" by the cleaning guy format.

[@crazyman3157]

Great video and full of little details all explained in a way the average guy can understand all the while showing what the extra time and money are paying for. You guys truly care about the customer, hold a high stand ward for quality, and do the extra things that may go unnoticed. Some may call that OCD but in my mind, it is not just the company name on the product, pride and going above what may be need brings the satisfaction of a great job done. All the details show in the end product. Start solid and square you end the same way. The Cleaning Guy is a bank of knowledge, awesome that you guys have this platform to pass on years of knowledge and shed light on all that goes into your work.

[@chrisslaughter5482]

Like the detail he put n to telling what needed to b done

[@jimleane7578]

Dang man! Imagine what you could learn if the cleaning guy handed you a broom! Full respect guys.

[@billyj.williams2341]

Nice explanation and demo.... that's one of the nicest/cleanest in use crank grinders I have ever seen.... Back when we still ran over the counter GM 350 Steel cranks, I often had to take them to 2.0" small journal rods to fix the stroke and index.... of course I could get them to 3.5" stroke that way as well.😂 I was taught the same thing about polishing and grinding directions.

[@lbh002]

Not bad for a cleaning guy. ;-) You guys are brilliant.

[@logancarter2134]

This is the best episode of y'all yet!!! Can't wait to see final assembly of this motor.

[@02f4irider]

Love the details you guys put out. This is the type of stuff the small guys like me do not know about. Typically, a crank is ordered and measured for bearings but the stroke is not something i would think about having checked. You would think that with it being new it would be in spec.

[@bryandevries7210]

I'm sure the precision will really matter when its winding out. Its amazing how meticulous this is. I'd really enjoy this line of work.

You are probably one of the best machine shops in the country. Super high dollar race engines don't get this kind of treatment. I worked for a Co, one of there mottos was, don't give the customer only what they pay for, give them more then they expect. That is you 10 fold.

Who every said being O.C.D. was a bad thing was never a machinist. Bravo you guys are artists.

[@StaticMusic]

I enjoyed this one! Great explanations too! Really talented Dad

[@joracer1]

After grinding cranks for years, i noticed especially on sbc cast cranks they tend to twist as they get miles on them.. usually in mild 350hp performance engine applications. You would have to allow this out of index crank on a regrind or the cranks would be tossed out. Also note on race cranks example $2200 crankshafts, they would not twist itself out of index even when making over 600hp for several race seasons.

[@EldonHoward-o2p]

i would luv to see an offset grind to lengthen the stroke by reducing the rod journals

[@roberthicks9191]

Wow, the knowledge of this man

[@raindeergames6104]

I've always wondered if the crank loses durability if You grind so much out of it. Does it not remove the hardened layer of the journal? Absolutely amazing video guys

[@scrappy7571]

It's all in the details, very nice!

[@stephendey5576]

I don't believe it is as insignificant as you say. It's performance may only improve insignificantly but engine longevity will significantly improve because the tolerances allow for way better lubrication. The roundness will decrease vibration and related metal fatigue. The engine will stay together and perform longer.

[@JAMSIONLINE]

The roundness and taper 100% we believe is going to be a SIGNIFICANT improvement. That is why we went to all this trouble. The index being off less than a degree will arguably be immeasurable difference.

[@watajob]

I'd be willing to bet the folks that build 10,000 HP top fuel engines do not pay this kind of attention to detail like the cleaning guy does. A CNC machine is a lot faster but the lifetime of experience can't be replicated by it.

[@drewmurray2583]

how would you grind a crankshaft with 9mm wide offset rod journals? How did vw do it? I am thinking cnc lathe maybe? I have always wondered

[@LTXwooshie]

Did you use press fit plugs on the front oil galleys, or did you tap them and use pipe plugs? I'm just curious as in most Chevy small blocks I tap them and use pipe plugs.

[@jeffgriffith7003]

You do very nice work! Now I am a bit angry at several local shops, as they have never polished a crankshaft of mine as nice as yours looks. In fact one polishing job seemed a bit suspect to my untrained eye, but not being a professional I assume they knew something I didn’t so after checking my bearing clearances that were in the specifications, I assembled the motor and it wiped out all of the rod bearings, the main bearings didn’t look much better. I had the crankshaft polished again at a different shop and looks slightly better but I have yet to actually check the journals with my chronometer to see if it’s still usable with a standard bearing. I’m suspicious that it will be in spec after two polishing jobs.

[@mikemclean8570]
