Got it making some decent chips vs. Long strings in some aluminum today. Seems to be the a combination of tool geometry, angle of attack, and depth of cut.

I was not prepared for how big of a mess this thing can make in a short amount of time. Click image for larger version

The best thing you can do to learn is watching YT vids on machining.

Thanks I watch Adam Booth quite a bit (ABoM79) and a little bit of that cutting edge fella down under. Definitely good info, but of course I have to scale things down a bit. I won't be taking a .250" depth of cut anytime soon, lol.

Ahhh, but it is a nice feeling when you do get a lathe that is capable of a .250 doc.

Even more fun when you basically build one in place from parts and start boring holes!

Yup, and with the OP's Lathe you can grab a Dewalt driver, some self drillers in one hand, tuck the lathe under the other arm, and screw it to the wall, and now you have a "Mini Bullard".
Position a 5 gallon bucket under spindle, for easy chip collection.....

5” induction Hardened Chrome Rod, 13’ long. Machining 3-1/2” 12 TPI on each end. One end 4.7” long, other end about 7”

Seen taking a .250” DOC, 1/2” diameter. Worked better after sharpening toolbit after initial hard layer removed in one pass. This layer is about .100” deep. So in two passes, I had removed .750” off the Diameter.

Default Finally - A lathe

Wish I could find a source for some of that chromed rod. At least a reasonable priced one.

That’s an impressive cut with that material for sure!!

Good luck. Our costs have doubled in the last year or so.

I can have a supply of old ones, but boss is very reluctant to have just anyone go thru our scraps, so I don’t take much.
