I could use some suggestions folks, thanks.
I've made a few full profile compensators in the past, but have always put them on a bull barrel. However this time I have a standard diameter barrel and would like to cut a integral cone into the back of the comp.
In my limited/hobby type thinking, I have two ways to approach this: One would be to chuck it up in a four-jaw chuck and very slowly take interrupted cuts out of the piece of 4140. It's 1"x1.5"x3", and the .406" bore is offset towards one end. So I'm going to be whittling off a fair amount of steel using a interrupted cut. FYI I have some HSS bits coming so as not to destroy my carbide inserts.
The other way would be to stand the rectangular piece on end on my little 6" rotary table. The problem with this is that I'm unsure as to how I'm going to secure the piece to the RT. I don't have a small front-mount 4-jaw to put on the RT, and can't afford to buy one right now. And I don't have a little machinist's vise to clamp to the RT. All I have on-hand right now is a hold-down kit. I have already made a mental note to myself to find a front-mount four-jaw chuck when I can afford it.
Any suggestions how I might accomplish this using the RT? Or should I just wait for my HSS bits and have a large mug of coffee for when I have to cut the cone on the lathe?
