funny thing. I had bought a few 12" round bars of steel. 1/2", 3/4" etc diameters. like 4 or 5 bars. hadn't used any until today. tried to make the shaft for the table lock out of the 1/2" pc. cut like putty. tried, several different turning tools, tried every freaking rpm speed, tried different feed rates. was freaking out as I haven't had a problem getting a reasonably decent finish before (not that I've cut all that much). was leaving ridges like a fine rasp.
after a long time and much trial and error I put several different pcs of steel and aluminum in the lathe and they all cut fine. it was the type of steel! had no idea. ended up using a 1/2" zinc plated bolt and it cut fine. anyone else run into this?
