Save your money and just buy/use a torch.

I've used this method many times and it will surprise you how well it works.

Start with a smooth finely sanded edge and take it from there.

I could not agree more that fire polishing (or other heat polishing) is the quick and dirty answer here, if you only have a few small pieces to do on occasion. For production work, there are other good answers here.

If it was me, I would do the sanding, then take an old dirty T-shirt and rub the hell out of the edge until looked pretty good, then go on about my business. I know the T-shirt trick works pretty well on motorcycle windscreens/windshields (depending on which side of the pond you reside upon).

Sand the edges with progressively finer fine sand paper until you are using extremely fine sand paper. Have this mounted on a disc or a belt. A stationery belt/disc machine works best. When you reach an acceptable surface fineness, flame heat the sanded edges. Be careful not to heat the plexi too hot or too quickly. Gradual on the edge that you are polishing works best. If you have access to a bunsen burner it works very good. Use slow but not too slow, gentle movements over more than just one spot at a time. If you heat it too hot or too fast it will either bubble, droop or start to turn brown/black. Some heat guns will also work for this.

The best and only way to do a good job at this is to experiment and practice, experiment and practice, experiment and practice. Before doing a "final grade" polish practice on a scrap piece of plexi of the material being used.

Takes a while to do but you get the surface you want, not the edge with burrs, un-square edges, crooked edges, and other imperfections you will have to fix before working with the plexi.

Good Luck, Old Salt
