> Why waterjet as opposed to laser cutting?

If laser cutting can do it then that's fine. Laserstream didn't suggest ano=
ther method as an alternative. I assumed, from their blurbs, that waterjet =
would be more suitable for a heat-sensitive material. Bob's gears show that=
 it can be done with waterjet

I'll ask

I've made gears and gear boxes of plexiglass like you are referring to usin=
g laser cutters and waterjets.
Both work equally well and both required a few teeth to be cleaned up using=
 a file and sandpaper.
Fifteen minutes cleaning a few teeth is much better than hand cutting all o=
f the teeth.

And glycerin makes a nice clear lubricant for the gears once it is assemble=
d.
