Help with bearing and collet use/design please...
Toolpost thingy to mill/drill/grind/etcetera:
1.5 x 2 x 3.5 inch block mounted on the toolpost stud, spindle hole drilled
on the centreline of the lathe, small motor mounted on the other end and a
few pulleys to connect it to the spindle.
I'll need a simple collet to hold mill cutters with a 3/8" shank. Right now
I'm thinking of a nut with an internal cone and a collet that sits in a hole
drilled in the end of the spindle, like a large version of a pin-vise; but
should I be using the flat which is ground on the cutter shanks?
Suggestions on the whole arrangement are welcome.
What kind of bearings and arrangement of same should I use for the spindle
that will turn the cutter?
Anything else I should figure out before the hacksaw stage?
