I'm fabricating a replacement for the part shown in my attached sketch. The severely-worn part is my locking cam lever, used to secure the tailstock of my watchmaker's lathe to the lathe bed ways. I've got the main body made (pretty simple, really) done - now it's time to turn a new handle.
So...my question is, what is the formula to figure the half-angle for the tapered part (obviously, minus the ball-end)? The length is 0.758" (but I'll call it 0.760" for simplicity's sake), and the diameters are 0.146" at the narrow end, and 0.218" at the larger end.
Instead of you guys just feeding me the answer (although that would be nice, too, just so I can get going on the project!), I would like to know what the correct formula is, so I can figure similar equations in the future.
Thanks!
