So I am screwing around with the lathe, playing with different tool grinds, feeds and speeds to get that mirror finish everyone on youtube seems to get. I had a piece of 2 inch pipe 6 inches long that I slapped on the 3 jaw gripping on the inside hoping to get a good surface finish. First cut was OK meaning I could see the shop lights reflecting off of it, which is pretty good for me. So I regrind the tool and give it a little more radius and set up another cut at my slowest feed which is .0015 per revolution. Touched off and adjusted for a .001 cut and let her rip. It went about 1/8" with some smallish chips and then it started cutting without breaking a chip until I stopped it 1/2" from the chuck.
By my calculations I cut 5.25" roughly with a single wiry chip. I measured it and it is truly .010 by .015 inches in 1 continuous chip. If I am calculating correctly the chip should be right around 183 feet long.
I think I need to work on my tool grind some more to get the chips under control.
And just as a side note the surface finish is as fine as I have yet achieved. But that chip, damn.
