Well My big shop is just too cold for a day of lamination work. Had to move the project to a heated work space. Laying out pattern on Coosa sheet is very straight forward. What is not is fitting the Core to the transom void. You need space between the core and old glass work to push the wet fabric into mixing it well with the thickened epoxy already troweled into every void with prejudice. Next there is a bevel in the transom, you must transfer the bevel to the replacement core so it lays fully flat against outer skin. All excess epoxy will be micromanaged and policed up so little grinding will be necessary to add second layer.
Included in this post are pictures of foam sheets sawed on a table saw to bevel so 1708 will conform better. These foam forms will be laminated over a layer of 1708 with two more layers of 1708. I'm having to work backwards from today's manufacturers. Here at best if over horse-powered is a high 50's MPH boat. Any more stiffening on the inside really gains me no benefit. The transverse bulkhead is rotten, poorly laminated, and very much needed. I will have to cut it out and replace after laminating the skin stiffeners. The hull was prepped with extra blocking under the Bulkhead to keep the boat hull from sagging outward when cutting is complete. I will be adding 2 recessed boxes to fit 2 PC925 Odyssey batteries forward. At 44lbs total weight I would like the space in the aft hatches over any gains in speed for having all the weight aft.
For the guys on this site that like to make their own jigs, if you look in the background behind the transom the bench and wall of containers is where I make all my jigs. those Powder Paint Fluid Beds are over 30 years old. They have the vibrating motors in the bottom that today's Fluid Beds don't come with. The little toaster oven is used to bake the epoxy on. All the plastics hanging on the left wall is because the only retailers who sell baits within driving distance (30 miles) is Academy and Sportsman's Warehouse. Their buyers don't buy the colors we use on the coast. The couple that are useful are always, always sold out so I stock the wall from online purchases in bulk.
