I want to hold a tapered workpiece in a collet or chuck, preferably a collet. The taper is very slight, less than one degree but, it's there. The piece must be held straight. Many of these will be processed, I don't want to mess with 4-jaw anything.
I have one idea that has some potential, I think. I do have a reamer with the same taper as the piece, I thought about reaming a hole in a piece of round stock, turning it down to a thin wall, then cutting a slit longitudinally, sort of like a sleeve. The sleeve can then be chucked, light pressure will hold the workpiece inside the sleeve. I need to have the extra holding force because the small end of the taper will experience some axial force, I don't want it popping out of the sleeve until I'm done with it.
I have no idea how I'd make the slit, nor if it would work the way I think if I was able to make the slit.
Or, maybe there's such a thing as a tapered work collet/chuck, or a floating jaw collet/chuck? I haven't been able to find such a thing.
Figured I'd ask the experts here to see if anyone has done something like this?
Thank you.
