Looking for feedback on my repair plan. I’ve nearly finished grinding out the delaminated/deleterious fibreglass. There was a layer of chopper glass which was about 1/2” thick. It was delaminated and in poor condition. In the process of grinding this out, I gouged into the hand laid layer of the hull in a few spots. The top of attached sketch shows what I’ve removed. The bottom photo shows how I plan to reinstate the keel stringer and fibreglass. Due to the damage I caused, I thought inserting a layer of fabric would help bridge any resultant weak spots.
step 1: PB fillets at main stringers (to replace what I ground out)
step 2: tab the main stringers to replace areas that have been ground off
step 3: overlay the entire area with a layer of 1.5oz mat to create a live glass layer (allowing subsequent layers to bond better)
step 4: 6oz fabric X 12” wide tape the length of the keel stringer
step 5: pre-apply resin to fir keel stringer
step 6: peanut butter below the keel stringer, and install stringer
step 7: one layer of 1.5 oz mat over the keel stringer
I plan to use polyester resin for all the work.
Any suggested changes to this plan? Not enough? Too much? Not feasible?
