[QUOTE="bamban, post: 2245827, member: 17722"] I am not totally convinced that carbide inserts had to be ran at high speed. This was threaded on my old Jet 1024 running the lathe with the VFD toggle. This lathe also has a proximity sensor that I can thread at 400 RPMs, which I do most of the time. This a project for a friend while he waited, when the subject of HSS and Carbide came up so I set up threading with the 30 RPM toggle speed. I had the stick out far enough by design and plunged straight it with the cross slide instead of running the compound. I say not bad for old worn out lathe. Just learn to live with the machine limitations. I am not a machinist nor a gunsmith by trade, just a retiree hacking away at this machining stuff. [ATTACH type="full"]286783[/ATTACH] [/QUOTE]
