There does not need to be a bond. The stringer is a tight fit and is incased in the glass so it can not move. The most important thing to do is make sure there is no chance of water getting in. I will also apply resin to the 2x10s before they go in. Once in I will wrap two layers of 1708 over them and down the sides. I also have to cut the bottoms to match the angle of the hull.
I am not sure what void your talking about. The stringer is cut to fit tight against the glass on the sides and cut to the same angle as the hull of the boat. Other than a little thickened resin that goes on the bottom it does not require anything else. If you read back I had already said I was going to coat the stringers before they go in even though they don’t need it its just a bit of over kill that I am happy to do. The Stringer I removed had been in there 39 years and it was dry as the day it went in except for the piece that someone cut into the glass near the transom. When the stinger is incased in glass properly it will never see any moisture. I also check them with a moisture meter before they go in to make sure the do not sweat.
Thank you. But its far from easy. Proper tools are a big help. I fought for over two hours to get the first stringer out with out damaging the fibreglass the second took about an hour. Also cutting the hull angle on the new stringer was no easy task. I love the challenge.Yeah you are making it look easy!
I also use titanium coated bi-metal blades. They seem to hold up well. I love having the dremel ultra saw. It cuts fibreglass like butterI been using the Fein Bi Metal blades medium tooth one
Works well
The fine tooth ones was taking too long to cut
Finished cutting the stringers tonight. They will not be going in for a while but wanted to get them cut and ready. Fist 80 inches is a 20 degree angle then another 60 inches at 30 to 35 then increasing from there ending at about 58 degrees. And fine tuning will be done with a wood rasp and sanding. I will have some more pictures coming Sunday.
