I found a local supply for Coosa except they only carry Bluewater 26 and in 1/2" 3/4" and 1" sheets. Would there be any advantage of 1" + 1/2" over (2) 3/4" sheets, (2) 3/4" sheets is ~$30 less than 1" + 1/2" but if I dont mind going either way if its better. Also gluing the pieces together, layer of glass inbetween (mat? biaxial?), or just thickened epoxy (Thickened with cabosil?), I've seen both on here?
So my procedures (make sure I'm not leaving anything out).
- Finish grinding out the existing outer transom skin, wash and then clean with acetone several times
- measure and cut the coosa and then epoxy the two pieces of coosa together
- test fit new core and grind out as necessary if needed, drill 3/8" weep holes in the core
- lay down a layer of 1708 on the inside of the outer transom skin then when its tacky lay another layer of 1708 on top of that
- slather back of core with cabosil thickened epoxy and set it in place and clamp down, clean up the extra epoxy that weeps through holes/top/bottom/sides, using extra along sides and bottom to form a radius for the glass to lay up against easier
- after that sets up remove clamps and glass over new core with layers of 1708 each over lapping the previous (4" beyond transom, then 8", then 12", then 16")...(how many layers do i need?)
- let that set up, and admire my new rock solid transom while enjoying a cold beverage
I miss anything?
