Being a 1 in 10 taper I get 5.711 degrees from center line.

If im going to set the compound on my lathe I figure I better make male and female, brass and graphite joint forming tools with an air passage.

Does my figure 5.711 degree sound right? Does anyone have some charts with the actual dimensions of standard joints.?
Most of the charts I found are arbitrary as hell. Im shooting for the gnats ass so my tools will make joints that fit others perfectly.

My trainee is wanting to make rigs and buying clear joints is not in the plan at all, sure as hell will not put a clear joint on a colored piece.

I have stock ordered for graphite 14mm to start. will do some 10MM and later some 19 mm.

Any information would be helpful.
