So I have made some more progress on the trihull. I have my transom glued to the outer skin with peanut butter, stringer frame installed and filled as well as taking care of a small problem along the way. I forgot to take pictures of the transom being clamped but basically clamped a 2x4 on edge across the top and then screwed a board to the new transom through the drain hole to hold the bottom. probably wasnt the best solution to clamp the bottom as it cause a void between the transom and outer skin in one bottom corner. I will get to that in a minute and how i fixed it.
Transom fillets
For the stringers I mixed up some PB and put it in a gallon ziplock bag and cut the corner off. I put a heavy bead down the bottom of each stringer and then set it in place as it naturally layed with a wiggle or 2 to help it squeeze out the excess. I smoothed out any squeeze out with a spoon and let it set for an hour before doing all the fillets.
So this is the void i was talking about...tapped around with a screw driver handle in a grid pattern to determine where exactly the void was and how big it was. Everything fit tight around the edges but I think it was a lacking of clamping the bottom corners on my part.
So I came up with a plan to fix it and did just that. I ended up using a hole saw to cut 2 1" holes in the outer skin only. Then I used some tape to make a sort of funnel to pour the resin into. I only filled in one hole but drilled 2 so the escaping air that was being replaced with resin had a way out. Also pushing in and out on the outer skin helped make sure I had filled the void completely. after it hardens I will just sand them off flush and paint over them.
I also picked up 2 sheets of 1/2" acx exterior grade plywood for the floor and got it all fit into place. After that I sealed the bottom side with a layer of 6oz fiberglass cloth and dry fit them to make sure the extra thickness hadnt cuased any problems. When it all gets glued into i plan on using SS screws every 2 feet and at the seam to ensure good contact and squeeze out of the PB.
I have a few more things to work on with making the outboard mounting holes in the transom watertight but I will work on that through out the week while I wait for what i hope to be my last shipment from us composites to arrive. I plan on spending all day Saturday getting all my remaining fiberglass cut out and layed up. 4 gals of poly resin and about 15 yards of fiberglass...should be make for a long but productive day. If any of you have any question on of the steps Ive shown dont be afraid to ask. I can tell you every detail of how i did it and im sure there are more than a few here that can help you even more.
