Some photos as of late:
Pre filter for the shop vac. I guess I thought the can would hold up to the partial vacuum a little better.
I put a scrap piece of expanded metal in there to help hold it's shape. It worked a little better.
Got the transom ground down some. Gonna take a few tries to get my grinding muscles up to speed. I was surprised to see how poorly the mat bonded to the roving on the transom. You can see I've ground a lot of mat away and aim to keep going.
Looks like they used coremat in the layup of the hull sides. Is this common?
