Delrin square tubing or angle bar? John Doe 06-26-2008

Anybody know where to buy Delrin square tubing or angle bar? About
3/32" to 1/8" thick.

I don't know if "angle bar" is the proper terminology, what I mean
is like flat bar that is folded 90° along its length (common for
steel/aluminum).

Hollow round tubing probably won't work.

Thank you.

Hollow round tubing "probably" won't work? Given that you'll have a
much easier time finding round tubing than square tubing or angle,
wouldn't it make sense to first rule it definitively in or out?

You can readily get Delrin in rounds, round tube, squares, flats or
sheets. Even hexes. Square tubing and angle may be available, but
are certainly not common. You could, of course, mill the angle stock
out of solid squares.

Wouldn't it warp?

Probably depends, some Delrin compositions are advertised not to absorb
moisture.

I was thinking more of the extrusion stresses being relieved if
milling angle from the square. If you could find extruded profile
angle, that should be fine.
