Anyone routed Lexan? My friend needs some louvre slots cut in a rear window /engine hatch. I don't think it will be a problem, but any advice would be appreciated re cutting speed etc. I figured I'd try to keep the bit speed down a little, keep the tool moving & try to "bite" as little as possible. I'll lay out the pattern on MDF and just use that as a template with a pattern cutter.
i seen on tv where the guy took a razor blade, , "very sharp one" Cut the lexan as deep as possible in 1 or 2 passes,,,then pour alcohol in the groove, , light it on fire and bend it off. It cuts perfect. But that was for big curves and straight lines, , , if its a really tight curve, then that prolly wont work.

lexan is easy to router, but get a friend or hire an imigrant to spray wd-40 on the blade and the plastic every 2 seconds or so to keep it cool so it cuts smooth

You've got the right idea with the MDF pattern. A tip to improve and reduce your finishing time. Make two templates, one about 1/16" bigger than your finished template. Route to that line first and then go back and finish off with the correctly sized template. By removing only a small layer on the final pass you will get less chipping which means less sanding/buffing.
