Laser Cutter Schematics for a Replacement Insert for a Delta 36250 Miter Saw

I drew up these files to run on a laser cutter, to replace a broken, flimsy, plastic insert on a Delta 36250 miter saw. For specifics on how I went about it (with pictures), I wrote them up on this blog: https://movim.slrpnk.net/blog/jacobcoffinwrites%40slrpnk.net/fabricating-a-replacement-insert-for-a-delta-36250-miter-saw-AjluxY

I'd recommend using 4.5mm or 5mm plexiglass, though you could take the vector and extrude it as a 3d file (assuming you've got a 3d printer with a large enough bed). Personally I used impact modified plexiglass, but mostly because it was a gift. Otherwise, tap plastics sells a recycled clear plexiglass which would work fine and is affordable. If you want to avoid fogging the plastic (in case you want to paint something on the back) I'd strongly recommend masking the surfaces with painters' tape. I left the tape on while using a drill press to chamfer the holes (so the screw heads would be recessed below the work surface). In the end, I needed to use a round file to adjust the holes north and south slightly. 

I hope this is a helpful jumping off point for you, in the unlikely(?) event that you have the right tool in need of parts, and access to a laser cutter.
