A friend who owned a machine shop that went belly up gave me 26 5C
colletts from 1/16 to 1-1/16".
I would like to make a collet holder for my 12" Enco lathe.
I'm thinking of making the holder from alminum because I have a
suitable sized piece.
My question is whether aluminum will hold up for this type of use?

If you could machine it the first time, you could also clean it up
when it wears. A spin index spindle has the right internal taper and a
short threaded draw tube you could extend.

Its a lot of work to make a collet holder.

Looking though the Mar/Apr Home Shop Machinist I noticed an ad
that may be of interest.

A 5C collet chuck for 139$US and chuck adapters for 32-45$US
depending on your spindle nose.

If you have a face plate and don't need through collet/spindle
capability you can use a collet vise for 30-40$.
