Those Pacemakers have so much torque. I was doing the same thing on a Pacemaker down at the rail yard. Taking .500" off the diameter and it didn't even break a sweat.

That’s an impressive cut to say the least. You have an assembled quite a shop man. That equipment is all really good quality, right down to the workbench’s and vices. All the thumbs up 👍 👍👍👍

Im a gunsmith. HEAVY turning is impressive! thanks for the video

Very nice job, well done. The American Pacemaker is a workhorse. Thanks for sharing the process. Have a great day.

Very nice ! Thanks for sharing ! Glad the horizontal lived up to your expectations !

Alan here from the UK. Just found your channel and really enjoyed this video. I like your laid back, but knowledgeable style. I've just built up a home machine shop so I'm looking forward to learning from you. Thanks.

That Pacemaker was eatin’! Great video man!

Oh man , I so enjoyed ! sure would like to see those heavy cuts in real time ..👍👍

Great job I am impressed.

Love your work, love your machines….

Whaaaaaat a machine! Awesome vid too!

Great job 👏

Awesome very nice part.

Happy Saturday!

A little over kill for a toilet seat!!!! Awesome work dude. Thumbs up Subcribed.

Fantastic mate, just subbed, love me some machining 👍

American Pacemakers and Monarch’s will chew thru some steel!

Nicely done

Enjoyed. 👍

Great sound and vidéo work..

On long mild steel bar stock I have done .750 diameter reductions in one pass on my grandfather’s 18x72 engine lathe. The limiting factor? Slippage of the leather belts. F.E. Reed, made in 1892. It’s last production job was 9,500 pieces circa 1970. It’s now in a museum’s steam-powered machine shop. Like a lot of old machines, it’s a beast- a 2-ton chainfall could only lift the headstock end.

Dad had an American Pacemaker. Great lathe.

Nice job

"But I'm sure you'll correct me in the comments..." Lol, amen brother.

Very good 👍

Coolant is a good thing!

Holly shit, that Pacemaker is a beast, awesome chips. That K&T is a perfect for what you’re doing. I’m wondering if the stock would have fit in the Colchester with the bed removed?

Excellent lathe work. But, regarding your set ups on the horizontal mill, you went the worst possible way in my opinion. If you took a horizontal cut, instead of a vertical cut, you could simply have held the piece in the vise. And for your other operation, simply bolt the work piece flat on the table and use a large face mill. Easy to indicate for both operations and easy on the machine as well. Thanks for posting. Keep those videos coming, as I enjoy your content. You are a good men!! Regarding the ''shorts'', I don't like them at all. Ten to twenty minutes formats are the best in my opinion. God Bless.

Great use of the Fireball angles......great video too.....thanks so much for sharing, Paul in Florida

Nice vid! I sure wish you had channel stickers available.....

great vid...have u covered what looks to be your radial arm drill in the back? I would love to see that on a video sometime..again great work.

Rough it out on the Do-all bandsaw. A band saw is one of the most efficient way to remove large amounts of material!

16:30, why reduce usability by docking the Throat.?😮

When you do all those doc, what was the feeds and speeds?

Ready for my Vanover shop fix, hit me!

WOW! is there such a thing as chatter with that beast

Negative rake carbide inserts cut by using the heat generated by friction to plasticize/soften the metal then essentially scooping the metal off the round being turned. Completely different method of metal removal from a positive rake insert which essentially shears the material off the round.. Positive rake inserts are fragile and could never survive this kind of material removal duty. Positive rake inserts work on low power lathes that do not have anywhere near the rigidity/stability of a lathe like this ATW pacemaker. It is possible to go more than 0.5" DOC with a CNMG43x insert as the chips will come off the cutting tool blue chunks when feed/speed/DOC is optimized. This is how these carbide inserts and ATW pacemaker was designed and intended to be used daily year after year...

Im surprised that setup in the mill worked at all. As soon as i seen it i was betting it would chatter.

Save time and avoid chipping insert tip by not facing to the center since you are going to drill and bore out the center?

What inserts do you use for rhoughing?

Heavy turning??? That’s not what Abom says!!! 😂. 👍🏻👍🏻

4130 is stress proof

That first attempted cut on the horizontal mill was never going to work - even if the cutter had been fine, the workholding was "optimistic" at best

No expert here,but shouldn't you dwell a bit after a deep cut on those chamfers? They look out of round. Because the tool was taking a deep cut at such a huge diameter,the tool being pulled back while in a big cut would make me think it cut more on one area than the other

that is a ucky green why not a real machine grey

The first thing to do is punch as big of drill through the center and get that out of the way. By taking out the center first you don't have a chance of disturbing the concentric diameters that you have already turned. Also when later you are facing, you won't run out of surface speed on the smaller diameter. You should have ditched the idea of holding the part in a vice. Strapping it directly to the table would have been much more rigid. Maybe in twenty years you will stop screwing up. Good luck.
