I'm considering trying my hand at making my own rifle compensator. I am planning on making them out of 4140 but I have a few questions on the methods I was planning on using.
I have a South Bend Heavy 10 lathe and an import mini mill. My plan was to:
* center drill/tap the inside
* put the stock between centers and turn down the outside to X diameter
* Do any kind of aethetics (grooves, etc)
* Place the compensator in a horizontal rotary table on the mill
* Cut the ports (either along the axis or perpendicular to the axis) at 45 degrees either side of top center (placement is up for debate at the moment)
In playing around with this idea, I chucked up a piece of 1" aluminum in the rotary table and attempted to use a ball end mill to cut some grooves along the axis of the rod. I got quite a bit of chatter and the cut was not clean at all. I was taking very light cuts.
I thought maybe I needed to buy/make some kind of tailstock for the rotary table but now I'm wondering if I am going about this all the wrong way.
This is similar to what I was thinking:

It is a flash suppressor and not a compensator - but same idea.
Has anyone here made a compensator? If so, what was your method - or if you haven't made one, how would you go about it?
thanks,
Kevin
