Both sides were sanded and laminated the third piece, figured out that if I nailed the center jam blocks it would keep it from moving. Also it was easier to use the epoxy right out of the fridg. I still used extra clamps even though I not sure it needed them, I won't be able to keep using them the more I add to the spar. it's only for my own piece of mind.
I started cutting the wedges for the main spar and will sand them and maybe secure them on the next day.
