Polishing Plexiglass Edges

Use a file and/or sand paper to smooth the edge as much as possible. IF you used a router to cut the plexi then you won;t need to sand it much.
Fire up a butane torch with a yellow flame and heat the edge - go slow and move the flame a lot because the difference between a nice clear flame edge and a bubbled overheated nightmare is about half a second..
I suggest you practice on scrap pieces first. [img]graemlins/thumb.gif[/img]

If I remember from my gr 8 plastics class, you can just use a buffing wheel attachment with a bench grinder. After sanding the edges of course to get rid of the saw blade marks.

I do it with a buffing wheel and compound. It takes more time but is harder to screw up and the results are great. Firt sand with 80 then 220, and finally some 300. Then use a buffing coumpound and wheel. If you want a frosted look, just stop at the 220 sandpaper.

Just a FYI, plastic shops don't use propane or butane. They use something that burns cleaner (I forget what the mix was, oxygen and something else).
Once you flame polish it, if you clean it with alcohol you mess up the flamed edge too.
