Layout for deck and cockpit. Using paint thinner as a weight is not a good idea.
A crack started as I began to curve EPS.
It was a big crack.
A really big crack. Not that easy to put a curve into 1" EPS. I put a fiberglass band aid on the outside side.
Using hacksaw to cut out cockpit hole
Because of the crack, I started scoring the underside of the deck. My cutting machine making fore-aft cut.
The machine made with a 12" backsaw and clamps was a little heavy. It worked, but not great.
Because of the compound curve, had to score in both directions. I found Ryoba saw worked better than my machine. The saw had a line making the depth I wanted.
After another crack started, I added diagonal scoring.
Shaping deck to compound curve. Deck curves side to side and fore to aft.
Glassing inside of deck.
Testing to see if I could get the EPS to curve.
Fit isn't nearly good enough with jigs/clamps I've improvised.
Putting compound curve in fore deck has curved the back edge.
