Machining clear plastic and keeping it that way
I was going to say "acrylic", but then I realized that maybe I would be
narrowing it down too much. How hard is it to machine a part out of hard clear plastic and then make it clear again? Any gotchas? What plastic should one start with? What question am I failing to ask? The part will be cylindrically symmetric (i.e., turned on a lathe), about 1.5" diameter, 0.5" tall, and accuracy can be as sloppy as 0.01 in all directions. But it would need to be "pretty". Some plastic that is a bit more rugged in impact than acrylic would be nice (do they make crystal clear Delrin?) but I can't think of anything like that which would actually work in this case. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com |
