First i located the centerline of the canopy, marked it, then trimmed the mold flanges from the perimter of the single piece plexiglass canopy and smoothed the edges
For all canopy cuts i used the vans supplied norton cutoff wheel in a pneumatic die-grinder. The temperature in the garage was approximately 70 degrees F. I made all cuts full depth on the first pass. (as opposed to multiple passes as some do)
For smoothing edges I ised 220 grit in my orbital sander on a medium ot low setting. This produces a real smooth edge. I may smooth more later with 400 grit or so, but right now i doent see the point.
