Just a small job but important one. The STBD and Port Spar Pin is held in place with a recipical to top it sliding out. A Ply wood shaped block is made then held in place with Quick Epoxy. Then ply’s of bit are lied over the sides with flox in the corners. The Port wing Pin is put in place and needs a washer on the spar cup to give it a hard point to lock it in position. This is bonded into position and pys of bit are laid over the top.
