I can only run maybe 1 1/2" - 2" on mine, so it's not enough for any longer pieces, like barrels and such. Or do you cut it one section at a time?

I cut the entire taper .015" at a time. Just move the table down and pick up my zero.

I'm not sure if you can contol a motor precisely enough to cut tapers, seems like you need something pretty advanced to make the compound screw run perfectly syncronized with the lead screw

Why would I need any synchronization??? My manual feed [my hand] isn't synchronized...

I just love getting whipped by a hot wad of swarf when it gets wound up and thrown at me.

Yeah...A nice long snake that suddenly whips around...Heh...
Here's one for you...I have a replacement engine for my infamous riding lawn mower; it has an exhaust pipe with a 1" male pipe thread for the muffler...The threads are all rusty, I can't get the new muffler on...It's a tight 90º bend, how do I chase the threads???
It won't unscrew without breaking the cast iron cylinder
(don't ask me how I know) and there's not enough room for a conventional pipe threader...
Anyone have any ideas???
