on page 38-03 it says drill the canopy first with a 40# drill bit, than later #36 than again #27. where do you find these drill bits made for drilling Plexi?

I used Permagrit tool to countersink the screw holes (https://www.permagrit.com/kt2/)
Those look interesting...what is the advantage of using the Permagrit tool vs. a conventional countersink bit? I have used conventional countersink bits on plexiglass (canopy & landing light covers) and they seem to work fine. They also work fine--for a while--on fiberglass parts, but get dull quickly. I notice the Permagrit countersink is advertised as being good for composites...are they are less prone to getting dull when cutting into carbon or glass fibers? If so they would be worth investing in for countersinking wingtips, empennage fairings, cowl, wheel pants, etc.
