Fiberglass Prep









Masked the instrument panel and the canopy arms today. Have about 1/8" of masking tape on the instrument panel top to hold the paper in place. Should be OK. I do not want to mess up my powdercoated panel sections. I masked the canopy frame arms on both sides and the canopy frame cove per the plans. Don't know if is was necessary but masked all anyway. Then installed the three layers of duct tape on the sides and the single layer of duct tape on the instrument panel top.

Then fabricated the foam blocks. A small angle has to be formed at the aft portion of the block so it mates with the canopy skirt. The block also has to be shortened. Then the interior angle has to be formed per the plans. Raised the canopy and used a Sharpie to mark the cutline on the back side of the foam block. Used a hacksaw blade to cut it to shape and drilled the hole with a Unibit. As the Unibit goes to 3/4", used a round file to open up the hole to 7/8".

UPDATE: If I did this again, I would open up the hole only large enough to get a socket on the bolt head. The washer will remain in place and will not be removable after the layups. Reason being, if you open the hole to 7/8" there is a just a tiny bit of the foam block forward of the bolt hole.

Mixed some epoxy and added cotton flox. Put a piece of construction paper (cut to shape) on the foam and used duct tape to hold it in place. I should of left the forward part of the foam a bit longer. May have to glue a piece on both sides.
