Just out of curiosity, roughly what is the taper on a tapered sleeve bearing such as in the headstock? I’m not real familiar with this type of bearing, seems useful. I don’t need to know the exact angle, just ballpark as in is it like a Morse taper angle or more like an ER collet angle? Just curious.
Somewhere between the two... it is 4 degrees per side... 8 degrees included. I'm not sure what an ER collet taper is, but it's a good bit more, Morse taper is between 1-½ and 2 degrees per side, IIRC.
