Flanging Part 1

2 hours to glass flanges on one side of 4 ribs. The jigs I made were all 12 inches as per the instructions, but that is not long enough for HRIB1 so I will have to make longer jigs. Each flange has 2 layers of BID as per instructions.

I started by wrapping the jigs in plastic wrap and  inserting the rib. I used 60 grit sand paper to take the shine off both sides of the rib first.

The BID was cut to size and I poured catalyze resin in a stripe down the middle of each piece of glass. I then layered plastic on top and used a squeegee to spread the resin from the center of each piece out to reduce air bubbles. I then squeegeed off excess resin to the long ends.

When done, the glass was totally transparent.

I then opened the plastic and peeled each ply up being careful not to distort it. This worked well for the smaller ribs, but peeling up the larger pieces of glass was more difficult without distortion. I think when I get to the main wings, the flanges will have to be glassed in place on the jigs.
