Default Canopy Trimming

I'm working on the rear window and marked the "sigma" distance off the front edge. About to make the trim cuts for the rear aft window, then will trim the front once I get the tape line on.

What are best practices for making the aft relief cuts? Drill holes in the corners and then dremel/smooth the actual cuts?

What's the best way to shape the forward edge? 80 grit paper and sand to shape with a palm sander? Then a finer series to 400 last run?

I've read so much I don't know a nice clean way to do it right the first time.

Default Plex edges

For me 400 grit finish sanding on the edges is a minimum. I did 600 then wet sanded with 1000. A bit of overkill but no scratches.

On my -7 tipper canopy, I used a 12 inch block with 80 grit to fine tune the edges a the roll bar, then progressively finer grits up to 600 to polish it. I needed to take off about 3/16" to get the forward canopy it to size, and didn't want to use any power tools and risk the chance of overdoing it. Worked out really well .. 20 mins and done. The long block helped to keep the edge in a nice plane (no wavies!)
