Re: Extrusion sizes

Hi Smoke,

I agree with your additional questions, but the reason I left them
out is that for a cheap closed part, one could easily sawcut it to
the opening desired. This would reduce costs of supply and offer the
end user the chance to modify as needed.

I had also thought that if say 1" was the bearing size and 3/4 the
shaft size (pick any sizes you want) a simple steel, press fit sleeve
would allow the sized (larger) hole to be used as an end support,
again reducing parts counts and keeping costs low.

great idea about other uses. bearings ? stepper mounts ? leadscrews ?
pen holder ? electric motor bearings could easily and cheaply be
used to make a jackshaft, or spindle.

Also if everyone on the list replied... think I should make this a
poll ? (Bill, looking for your input here too.)
