You just have to love these long weekends. Cleaned up the tape joints (Took less time today and did not sand through but once. Cleaned up and shaped the laminated braces, Need to fill the small gaps in the laminations, and tape one joint that did not get tape the first time due to some twisting issues with the wood the first time. Quite a bit warmer out side today and temp is supposed to hit about 87. Preped for taping the joint and filling the voids in the lamination. Mixed a batch f epoxy and decided to pot it a little longer.
Air temp sure does have an effect on this epoxy pot time. 6 minutes and it was getting warm in the cup. I got to wetting the glass faster than expected. Moved on to the void filling found the epoxy getting to a pre- gel state. dumped the rest on the boat transom I am repairing due to bottom rot (It was never sealed properly from the factory, They just painted a piece of marine ply) I must say learning about epoxy and fiberglass is an experience.
Beginning the stitching process today. Had a brief moment of anxiety when it looked like I may have repeated the banana boat problem with the lower panels but I studied the model and decided that all was well. In the pictures you will notice a definate banana shape at first but this one is normal and comes out once the bulkheads and braces are in place.
First bottom panel is stitched and in place on the bottom. ready to do the second side.
Stitching is done with 18 gauge bare solid copper wire pushed through 1/16th inch holes and a 3/8 inch dowel to provide even pressure to the joints. The dowels act to keep the joints on edge rather than overlap. Note how visible the butt joint is on the bottom of the hull.
Another view of the stitches and a butt joint. The wire is twisted on the outside of the hull and will be removed after the joints are filleted. Fillets will be made initially between each of the dowels. When the epoxy is cured, the wires and dowels are removed and the remaining spaces are filleted in .
Both bottom sides are attached to the bottom. Note without bulkheads and braces the side try to stand straight up causing the banana shape whenthe ends can hang down freely.
Another view. This one really shows the curves. At this point I had to stop and cut out the other bulkhead and the stern covers.
Rest flat on the table, add bulkheads and braces, and the banana magically disappears.

One last shot and called it a night.
