But what I did was make a pattern out of thick construction paper then tranfer to Lexan MR-10. Cut out with a Bosch barrel jig saw with a very fine blade, taping the cut lines with blue tape. Ran some sandpaper over the edges and done.
To make the pattern, outline on the inside and on the outside, split the difference.
There are videos out there somewhere.

Best, Bret.
