I am trying to build a rotating pedistal that locks in place with a pin through holes in a concentric ring. I need the pin to be tapered so that it will enter the hole easily but hold the ring with no slop. There will be a lot of side pressure on the pin so the taper angle can't be so large as to force it out of the hole but OTOH, it can't be so shallow that it will bind like a Morse.
Is there a standard locking pin angle? I don't want to waste a lot of TGP rod experimenting.
