Hi all.I have been searching for a previously posted answer to my question but came up empty.In the process of removing the keel stringer i have noticed that the stringer was merely placed in the center of the keel along with 5 pcs of 3/4" thick plywood strips butted up to each side of the stringer .I assume this was done to allow the wood to conform to the shape of the keel.It appears that the stringer and strips were bedded with a chopper gun then covered with what appears to be roving, possibly with only 1 layer.This of course has delaminated to the point that i could remove the strips and keel stringer by hand just by cutting the glass next to where it is tabbed to the inside of the hull.I had planned on using resin and csm to attach the strips to the hull then 2 layers of 1708 over the top of them to attach to the hull.I have begun to think this design is inherrently weak.I think it would be better to bed the stringer in PL then tab it in place , put the plywood strips down over the tabbing and then cover with glass ,possibly 2 layers of 1708.All of the other stringers were tabbed in with a chopper gun and there are many more strips of 1/2" plywood that were stuck in place and covered with one layer of csm.I am looking for ANY suggestions here as i have not ordered any material yet but i am dead set on using poly resin as the PO had used poly to replace part of a stringer and even with his poor surface prep it is very sturdy.Thanks in advance
