9.5 Inch 4140 Gearbox Shaft Part 2

We continue on with the new gearbox shaft. In this video I show the finishing passes made to get it to size. After we fly it down to the boring mill for some drilling and tapping on the end.
We'll have one final video showing the keyways being milled.

I have been quietly watching your videos for a few weeks now and I cannot help but admire the values that you are sharing. Confidence that comes with intelligence and skill that you have gained from experience. Professionalism as demonstrated by your attention to detail and precision. Honesty and humility as demonstrated by owning up to your mistakes and finding solutions rather than blaming others or your equipment. Integrity as demonstrated by your hard work ethic and producing the best product and value to your customers whether paying or not. Family values as demonstrated by your stories about memories of your grandfather and father. Finally your willingness to learn and problem solve all the while sharing your knowledge with others. I would say that all of these qualities add up to a great roll model. Keep up the great videos and excellent work. You have provided thousands with knowledge, hours of entertainment and inspiration. Wishing you success and happiness.

You should write down your experiences. Something for your children and grandchildren to look at and appreciate. My Dad is your age and I've been trying for years to get him to write down some of his experiences but he's always saying it's a good idea and then not doing it.

I'm over 70 years old now and watching these vids took me back to my teens when I used to watch my dad working on machines like these when he worked for Shell Oil Co. I never did get the hang of centring a 4 jaw chuck as quick as both you and he could do it. Great vids. Thank you.

[@sambojohnson9375]

I have been in the repair of hydrulics and heavy equipment repair for over 30 years. And without out a doubt you have proven on your channel that you are a master, not just the small machinist but the manley- man world when it comes to the big boy world of heavy equipment. Love it. Been watching others on KZbin . No one touches your skills. Keep up the great work and please keep showing use your heavy maching videos. Heavy machinist is Abom79.

[@Antagraber]

I appreciate your videos. My father worked in the same profession in a Swiss industry. He was a passioned specialist, minoucious,... He even talk about to work in a temperature controlled shop to ensure that the (big) pieces had always the same dilatation rates, etc.. Your videos bring me a lot of memories. He's not longer with us, but I am sure he would have enjoyed your videos too. Thanks for posting.

I have no clue whatsoever of what you are doing but I sat thru part 1 and your meticulous work ethic is what made me come back.

[@geraldheitman7687]

Wow I found your videos by accident. You so remind me of my father a journeyman machinist of 40+ years. You are a true tradesman be proud of your profession !

[@wayneg3127]

20 years under my belt. Job shop machining. Nothing like dealing with chatter and taper with old machines, I guess thats the ART part in industrial arts. Seen alot of newbees and wanna bees come thru the shop over the years, some fresh out of school that couldn't handle the fact that you had to make the machine do what you wanted it to do. Nice to see your work.

I retired running a 24 inch swing 12 inch hollow bore Lehmann Lathe very much like yours just 6 years ago. I cut threads for the oil industry till my retirement. This brings back memories. I loved watching you work. We ran coolant on everything we did and was wondering why you're not. It's a mess I know but our cutters lasted longer with it. Occasionally we ran dry if we slowed it down a bit but on long cuts we always ran coolant.

[@blue03r6]

[@alanslater4206]

I remember an old gunsmith/engineer I knew used to tell us how the apprentices used to have to clean out the machines and remove the chips etc. When he was teaching me a little gun smithing thats what he used to make us do too.

I think the first video of yours that I watched was the same shaft being made, I had typed in heavy lathe work into the search when I first got interested in machining a few years ago. Nice to see the same job again with a lot more understanding of the subtleties of the job thanks to your "tuition" over the years.Thank you

Everything you guys have got, I've got, courtesy of Harbor Freight, on a scale small enough to fit into two 5' x 7' garden sheds, butted together, with the center walls removed to create a single space. So I can't tell you just how useful - if somewhat humbling it is - to see how you guys do such professional work with seriously heavy equipment. Thanks for sharing this stuff, and I hope you'll keep it coming.

I will literally never do this or need to know how, yet watched both parts, great video.

[@comictrio]

The first machine shop I worked at specialized in heavy industrial machining and part of my daily duties being the shop newbie, outside of machining, was cleaning out the chip pans. Since there were always chips on the floor my boots would get loaded up with chips. When I got home the chips in my boots would catch on the carpet and the carpet would raise up with each step. My wife demanded that I remove my boots before I came into the house so I wouldn't damage the carpet and to stop loose chips from coming out of the soles of my boots and to stop us from stepping on them. Once a week I would go out on the patio with a a pair of pliers and dig out the chips from my boots. I definitely don't miss swimming in the ocean of chip from that shop:)

[@Abom79]

+comictrio I think any machinist experiences the same. 😆

[@the1andonlydjt]

I enjoy watching you work on "heavy metal". It is awesome knowing that machines exist that can work material that large. And that there are people like you that know how to use them. I enjoy all your machining videos. Great video. Can't wait for the final part.

[@obfuscated3090]

We direct machining students to these videos so they can get an idea of what job shop work is like. They are outstanding training aids.

Beautiful work. Nuts on measurements to tenths on a piece that big and heavy was a treat to watch. Thank you.

[@TheRidgewatbrad]

Thirty seven years in the trade and my best times were on a big lath doing big shafts like this. I did it just the way you did it. It brought back a lot of good memories.Like the chip shield for the steady rest and the belt sander . What ever happened to the trades? My boss asked me to work an extra year because he could not find another qualified machinist to fill the position, this is Detroit for crying out loud!

Nice work. Brings back lots of memories. I miss the old cave , coffee and smell of oil and steel.We use to put small brass shim stock in the live centers to offset the taper when needed, it did the trick well many times.

Two things after seeing this now for the third or fourth time: 1. You've come so unbelievably far in your weight loss and health goals, as far as I can see. Good for you, man. You should be proud. 2. I'd love to turn on a new video today and hear this old intro music again. Such a cool intro, with the gorgeous acoustic guitar and whimsical bell sounds almost making the workmanship seem like magic. Bring it back, Adam! =)

[@andyd1006]

Machine shop where I worked when I was in high school clean up was a major part of my job I had a shovel and a wheelbarrow. The machinists used to make lots of gearbox shafts. I cut a lot of 4140 loved that job

[@RumpLeINtiLINsKinnIN]

Great work on that shaft Abom. We love the big heavy stuff. The crane shots are always cool too. I can't believe yall dont have helpers or somebody to empty the chip pan and clean machines. You shouldnt have to be doin that. Although we're all very happy you can do filming at work again

[@Abom79]

+RumpLeINtiLINsKinnIN We do have a shop helper but I can't get them to help me clean the machines out. I don't talk about it anymore, I just do what I have to do.

[@xkblxcripple]

As a Fitter Machinist that worked my way up from the shop helper position (TA) I have since kept all machines I work on in peak condition and spotless, my employer was an underground fitter machinist that couldn't stand the mess and loved coming in at lunch to see there was no mess and I could freely move around the workshop without leaving a trail. I then took over the companies CNC machines and started doing engineer work, unfortunately my employer went broke and I haven't been able to make anything in years. would love to get back into it.

[@zoidberg444]

RumpLeINtiLINsKinnIN Its a job for an apprentice really.

[@EddieSchirmer]

i wouldnt mind shoveling chips and cleaning up work around a shop... heck i woudl do that for minimum wage 12 hours aday so long as i had tools to help move them all lol... i can imagine, depending on circumstance and size of the chips having a vacuum that would just such them all up into a bin you could then empty out, but then, a shovel is probably way cheaper haha...

[@eliascastillo1641]

Some times they’re lazy. I get frustrated getting my own material from the yard and wasting time while the shop hand is eating crackers, or flirting with the CNC girl.

[@t.d.mich.7064]

I've found a good way to align the tailstock center is to place an indicator in the chuck and indicate the point of the Center while adjusting or shimming the tailstock body. Good starting point and fine tune by miking in on a straight cut like you were doing. I did a lot of large work like this usually on Monarch Lathes. I loved the finished product. It gives you a sense of real accomplishment. Good job!

[@richardandrews6754]

Hi Adam, lovely work I found your channel recently and it is clear you love the machines as much as the metal itself. I used to work on old machines myself (German war requisition after WW2) worn out then let alone after another 40 years service so I know how you get a kind of empathy with the machine and clearly you have this and can work around the wear to turn out a first class job a joy to watch. from the old guy in the old Country stay safe.

[@sixstringedthing]

A thing of beauty is a joy forever. Or at least until a mechanical failure busts it. Loving this "heavy metal" machining stuff, I'll definitely have to go back and watch the older playlist videos after the conclusion of this job.

[@nigelpearson6664]

Centre drills are cheap and usable in drill press type drill, they help make the job go better. Beautiful work.

[@davidr.massey419]

While in my 37yrs. as a steel plate shape burner(CNC/Electric eye burner) i wonce cut (2) huge 12 ft. long crank shafts in the two dimemsional aspect. They were 11&1/8" 4140. Cutting thick 4140 and annealing it is tricky business! Plate was preheated to 1700 degrees for 8 hours before i started my set-up. There were so many turns it took 5 hours to burn, but the really cool part was imagining the hugeness of the maching process! This was about 1980 if that meens anything.

[@FarmCraft101]

Nice work Adam. It would be great on your videos to see the finished parts being installed and/or in use. Even if it's just a few stills that the customer sends to you, I know I would like to see those perfectly manufactured parts in their new homes, and I bet your other viewers would as well. Thanks for sharing brother!

[@Abom79]

+FarmCraft101 Would be nice but I can tell you pictures from customers won't happen.

[@royreynolds108]

[@FarmCraft101]

Well darnit. You need to get some new customers then! Where are their priorities anyway! ;-) Just kidding. It's a shame though. It would add a lot to the vids. What machine is this shaft going to be used in?

[@Abom79]

Many mill workers don't have passion about what they do, the equipment around, or the processes the company makes. If they do they probably can't share it. When I say passion, I'm talking about like us youtube creators where we like to share with everyone what we get into and see. A lot of guys go to work and when the leave, they leave the work behind them.

[@mikenixon9164]

Very nice work. Better tell the boss he needs a conveyer under lathe !

[@bpark10001]

One trick I use when turning in 4-jaw: I machine a step in headstock center so I can install it in headstock behind the chuck. I mount the work between centers, then tighten the chuck jaws down onto it. This speeds jobs requiring repeated remounting of the work. Essentially the work is between centers, & the chuck is the "lathe dog".
