Adam, as much as I love watching all you videos, I still think the best part of every one of them is the picture of you and you Dad and Grandfather at the end. Love it man.

My wife, Karin and I just had dinner, patés and baguette with a 2005 St. Emillion and we watched you whittle down that big ol' block or rusty metal. The best Saturday evening we've had in months. Your videos are so perfect it's really a delight to watch them. Thanks so much. I really appreciate your taking the time to write down feeds, speeds and DOCs, etc.

Been a machinist for 45 years, on the desk side of the shop now, love my Saturday fix to watch the chips fly. Thanks for another great video.

Another great video. I know it's more editing work but I think the tool specs and cut specs on the screen really give it a more professional feel

This is what I enjoy most on your channel the chips, shiny metal,smoke, and oil.The aroma of Industry I fondly remember from my days as an metal engraver.Enduring humidity, heat,and cold. Hot chips stinging when they find flesh.The sound of H S S taking its bite,Carbide hurtling chips of bronze, chipping the paint off the block wall like so many miniature missles

Man! You gotta be the Gravy King of Pensacola. Every week a video of heavy stock removal with nothing to do but dial in, pull the clutch, shovel chips, and work crossword puzzles. Productivity combined with nap-time. Criminal seniority. Nice discussion of inserts, feeds and speeds, stock removal, chip control etc. Buckshot chips are a PITA. Funny how a little change in chip breaker design makes the difference between a gentle cascade of chips down onto the carriage wing and a high velocity fountain broadcasting chips in a seven foot circle. Back when dinosaur crossings made me late for work, the tool pedlars used to flood the shop with "carbide calculators." These were specialized plastic coated card stock slide rules with scales and windows on which work parameters were set-up and feeds, speeds, RPM, etc were read out for machine settings. They also had brief tables charting material reccomendations, carbide grades, coatings, etc. Super convenient after a little practice and they fit in a shirt pocket. I'm good at mental math and a pocket calculator but these little slide rule gizmos were so much quicker and convient and they'd give you a half dozen data points for three input parameters. I retired with a 4" stack of them now long gifted away. Are these still offered? Would they be a topic for a video segment? You have a good ear for machine loading if I'm any judge but a load meter (am I nagging?) takes all the guess work out of maximizing a machine tool's stock removal. You got 15 horses? Put 'em to work. You can buy a cheap multi-function digital ammeter complete with a current transformer on eBay for $10 - $20. Thread a motor lead through the current transformer and run low Volts DC to the meter. Poke the button until the display reads Amps. They may not be super accurate but your electrician can compare its reading against his good one and give you a correction factor.

You know, when you watch the videos of how they rough forge these shafts it always amazes me that they're so accurate since they all seem to be working by eye.

Like the tip about recutting the center with the compound after your swap ends. I learn something from all of your videos. Thanks!

It's great that you can film at work again happy you and the boss could work something out to do so...

Your videos always make me wish I had been a machinist. Thanks, Adam!

I just love watching big turning... big lathe=chip chunker.. small lathe=sliver slinger LOL. I fit in the second category... I have learned a lot from you, Thanks!!

You are the Michelangelo of the machine shop! It's a pleasure to watch the pride you take in your work.

Another great video and such a pleasure watching a professional working. Thanks Adam.

Great work as always. Thanks for sharing!!! Look forward to all your videos.

It's kind of fascinating, watching this big piece of raw steel being shaped into a shaft,pulley,gear whatever piece of machinery is required. Most people just don't have any idea what kind of skills it takes to keep society running. Excellent work Adam, as always Ben

Absolutely adore watching these ol' ladies work hard

I like how fast paced this is. Thanks for the video Abom.

Thanks for taking the time to video your work.

Hello, love your videos. The part I love most is when the tool cuts into raw rusty unturned metal, the way it cuts into the rust and you can see how the piece is not turned true and how it has lowspots. Keep doing what you're doing, hope you're feeling better with your legs.

11:54 Machinist Calc Pro. Awesome calculator. I got mine a couple years ago, and later upgraded to their newer version Calc Pro 2 about 8 months ago. The layout is slightly different on the version 2 model, but still does the same things plus a couple of newer features thrown in. I've also got the updated android app for my smartphone. Both of which I use pretty much on a daily basis in the shop or office. Makes figuring out a starting point on speeds and feeds childs play. Our shop has a few users that are notorious for just throwing something up on the mill or lathe and running it at whatever rpm and feed the last person used it at. I hammer down that the inserts aren't cheap for a pack of 10. I printed out formulas for them to figure it out properly, only to get complaints it was too complicated. I bought a few of these calculators for the shop and finally some started using them. A great machinist calculator.

Looks like a perfect addition to the Heavy Metal Machining series.

Love watching those chips fly! Thanks.

Really like the panoramic view! It gives the full scope of the work to be done on the project. Great content....*as usual Adam!*

Thanks Adam. Awesome machining.

I like the shot of all the chips changing colors from the heat

I like how you show length measurements. I'm spoiled with a DRO. Im going to try your method on my next shaft job. Thanks.

I never considered how much material ended up in the chip bin until I started watching machining videos. That's close to half the billet in some of your jobs. Impressive amounts of metal removal. I'm not saying you should provide it but it would be interesting to see where some of the shafts you make end up in operation. That's heavy metal! Happy to watch it happen. Thanks!

Looks great thus far, you have inspired me to experiment with feeds & speeds lately, the chips have been a huge improvement on my end. Thx

Thanks for another Saturday.

You would have loved this old Monarch lathe we had at work years ago. Numerous times the old man who ran it was taking 0.500"-0.750" per side and that old machine never skipped a beat. It was also "slightly" larger with a 5 foot swing diameter. :P

nice to see some footage at your work again, heavy machining is the bomb.

Dude, love watching the big project videos :) Makes me miss machining from the 1990's :)

Just a lot of work that goes into those gearbox shafts, enjoyed the video and the experiment with the inserts

Good job as always, an art your job is

At 3:50 THE ABOM TORQUE !! Great videos Adam . Awesome when a new vid comes out !! THANKS

Woah! the old Pacemaker was pulling hard with that 432 insert. I think was as relieved as the Pacemaker when you called time and switched to your trusty Iscar!

Am very impressed with the way u setup the work piece and the tool. I pick up alot of things watching your video, i wish i will work in your best company one day

When I turn large Dia, shafts like this and the chips are coming off like when you first started to cut , even cutting .020” less depth can make a big difference, also I often move the tool in the tool post as a different angle of attack can also make a big difference . Nice job your doing , enjoying watching your videos from one Manual machinist to another. 👍

Awesome work there mate.

Hi Adam. When I was working maintenance at a welding shop about 12 years ago. I brought a horizontal mill back to life that looked a lot like the one you were using. After I made it rise from the dead they realized there didn't have anyone in the shop that could use it. So it just sits in the corner getting more rusty. Just like me. Bill from Seattle.

Great video!👍

Dear Adam: GREAT video, I really REALLY like the graphic detail you put in about the metrics, e.g. SFM, RPM, etc. It helps me validate what Im doing right and reevaluate when I'm significantly different--thanks! BTW, it takes real balls to power tap these shafts......and some ABOM skill. I would probably twist one off and spend the day digging it out.....way cool!

I used to work for a firm a lot like motion in the uk. I left that to work in maintenance for the gas industry. I’ve got a home workshop now with lathes and a miller but still miss the big stuff seeing a big lump of steel on the machine shop floor used to get me up in the morning. We made the mixer for toblerone chocolate I still tell people I made the shafts it runs on complete with 2.5” bsp left hand internal thread for the steam ports

Great work Adam, enjoyed! ATB, Robin

15:40 The torturous sound of metal bending to the will of Abom.

That's a nice 10 inch vertical output shaft you've got there. That's what she said. I'll show myself out.

That's moving some serious metal! Nice work, sir. TZ

You got some really good shots and lots of good info jamed in here.Really good video Adam, I enjoyed it. Thanks. Steve Summers

I dig the machining. I machined crankshafts for John Deere, Cummins, Cat and others. I would personally use a continuous stream of coolant.

As ever - watching huge quantities of stock removal is impressive! A real "blue chip" process :)

A new work video.......yea! Been a while since you were able to do a full one.

WOW... I think the best expression would be "Accurate metal art" beautiful...

GREAT VIDEO !!

Interesting to see how the design of the chip breaker insert is so critical as to the direction that the chips fly off at.

Serious metal! cool stuff Adam

these heavy metal removal vids are so awesome!

The shaft king!

Great skill indeed

I recognize the 4140 scream , getting it to chip is a pain depending on heat treatment condition, anything above condition P is annoying but it always gives a great finish

So that's how they get stickers off.

Making that lathe earn its keep! awesome

Range is hot. Eyes and ears !

Looking at the original shaft, you'd think with how expensive the piece is (not to mention the cost of downtime), there would be safeguards in place to keep it lubed and protected from such terrible corrosion.

I was going to say that it sounded like it was struggling a little before you dropped the speed rate and how happy I was to have my earphones on hahaaa I'm a div watching milling with headphones on.

Some serious metal removal in this series Adam

That must have taken time to set up un the lathe.. 👍👍 intimidating big cutting

great share man , The chips are AWESOME ! just not flying up .. LOL.. Thanks ..

the chips are beautiful :O 18:27

If the load today sounded worse that the same the other day - it might be the power company has browned out the power lines giving you lower voltage and thus lower current. Larger current to start and less power all of the time. They also can brown down so much lights don't trigger on. Take care. Good job.

Adam great video thanks for taking the time that is involved with putting such a video together. Which brings me to my question about how many hours does a big shaft like this take to make? I'm guessing 8 hours so far. Keep up the great work, thanks again for all you do.

Nice!!

Adam. Hi. Thank you for mentioning hearing protection. Hope you don’t mind my saying that I hope you are as conscientious about hearing protection as you are about eye protection. Enjoyed the video. Be well,

I love your videos. The machining and information you share is a treat. But, what always leaves me hanging is. Where do the parts belong when you finish? I would love to see a video or a photo of where the parts you machine belong. Gives a meaning to an end. Keep the videos coming!

Hi Adam, I really like these workplace projects and I am glad they allow you to show them. Have you ever "saved the bacon" by using a video file as reference? I am sure you get the odd repeat job that might benefit from a review. Cheers bro!

muito bom seu trabalho,,,,,,

I was worried the sticker was going to be too much for the cutting tool when you faced the other end.

That 10in diameter makes a noticeable difference on how hard it pulls the lathe over that 8" one you did a while back. I never tripped the overload protection on My Monarch until I was turning on the outside of a 16" piece. I was trying to take a cut like I would on an 8" and it would have none of that!! lol

Fascinating and impressive in metal removal. Is it possible to know, roughly, the initial cost of the 'raw' 10" shaft and also to know to percentage of metal removed for the new shaft ? Many thanks PS

How many speakers were destroyed while watching the video? 😄😄 Good Video like ever. 👍👍

Nice one. :-)

Glorious chips

Have you ever dropped a shaft on the floor? I put the chains on a big plate wrong in my time as apprentice, so it collapsed when i lifted it. I put the chains to wide. But got out from under it before it collapsed.

damn heavy metal

Guys just asking .. i overhaul rotary compressors and sometimes the shafting with the gear leaves marks .. do i need to heat the gear even more or its just normal ? Thanks And btw Abom79 really love your workpiece

Interesting cyclic sound as you're turning the big end, sounds like the bar has a harder section off centre . Do you ever fear you'll cut too much , just because it's cutting so well and h ya just don't wanna stop' :-)

I giggled when you faced off the sticker

Ты просто красавчик!

ohh fresh barstock or at least looks like its just brought in and virgin based on the fact it has a lable on it, time to make from scratch, do you ever use diamond tipped insert cutters, or is it not really a thing in machineing beside carbide inserts? also what is the differance between a regular ruler and a machinests scale? just curious is it more markings on the machinest scale?

Regarding the gentlemen at the end of this Video . The Gentleman in the center Is a ringer for my Dad. He lived to the age of 103 . The resemblance is amazing !

I was 10 minutes into this video and was just about to ask if that was 4140 or 4150 by the looks of the chips and finish. I happened to click "SHOW MORE" on your video notes and got my answer. :-)

What's that shaft on the back side of the lathe for? I'm guessing some kind of power rapid traverse for such a long machine, maybe?

time to put a bigger motor on the lathe hah

Maybe you can show how to adjust the tail stock if you cut a slight taper........ just for the guys that are new to machining

Iscar COMG, aka the "Right - No More Screwin' Around" tool... XD

how can you machine heat treated and tempered steel? that stuff is hard a hell

I miss the boring mill footage

10 Inch Vertical Output Shaft? Thats what she said!

Great video! Why do you drill center holes on the machine? You can prob save some time and just drill them by hand! :) I think they don't need to be in the dead center cause you've got material to take off anyway.

iirc you are supposed to lower DOC and leave or increase speed or feed with carbide when its having trouble like that, but i could be totally wrong

Is there a reason not to use spray welding to repair the original shaft? I'm guessing over a certain diameter you can not get it to optimum temperature?
