It can be brittle and scratches easily, but it is workable. If you are sawing, use fine blades with lots of teeth.
I polished some lucite a couple of weeks ago with flexible polishing sticks from Brownells. I think it was the 600 grit. Worked very well, but took a while by hand.
If you have a local eye glass shop, you may want to see if you can talk one of the techs in to doing the polishing for you. They already have all the trick equipement. Come to think of it, they may even be a source for some hardened plastic.
Good Luck...
