The task is to make end mill holders for my "Eklind" vertical mill
head,
that uses collets similar to a Bridgeport B3 (sort of a shrunk R8).

A sketch of a collet that would fit can be seen he

My material is 12L14 bar, about 4" long.
The lathe is a SB 9 Mod C., without a toolpost grinder.
I will be using a B3 collet as the template for the draw angle.

What order of operations will maintain concentricity as I drill, turn,
bore and ream?


Thanks,

Kevin Gallimore

snip good stuff
Cut your slots last, after you've
tapped the thread. Any changes at that point will be self correcting
when
the collet is in use. Deburr the slots well, naturally. Does this
make
sense? Need more info?

Except he said end mill holder, so he won't need the slots. Substitute
drill and tap setscrew holes last. I've got the same job when I get
my M-head with B3 collets up and running. Also 5C end mill holders
for the TM.

Thanks, Pete. Nothing like having your head in a dark place, eh?
