Time: 2 Hours
With the canopy off the frame and in the cradle I started working the holes to their final size. I am using the technique of opening the holes up and using a slice of rubber tubing as a shock absorber for the rivet. I used my plexiglass drill bit and opened all the holes to 1/4″. After that I used a dremel bit that looked like a 3/8″ ball and had a fine grit with just my fingers and not the dremel. This slowed me to put a slight chamfer on the edges and smooth them out.
