I need to make some spacers out of .01" acetal sheet. I've not worked
with it before.

I had planned to drill the 1/4" center holes, and then cut the 1" OD
somehow. Is this sheet flexible enough to stamp them out with a die in
an arbor press, or will I have to cut each one out using a hole saw?

Personally, I'd first look up the properties of "acetal," whatever the
heck that is.

A coworker here recently made a cutter for some Viton gaskets where he
needed to hold about three thou - he just cut one (cutter) out of some
piece of ordinary A36 steel he found in the cutoff bin, and used it in
the press.

But if "acetal" is rigid like styrene or acrylic or polycarbonate, then
just mill it - for quantities in the thousands, you might farm it out to
an NC shop.

Good Luck!
