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
