Not much to report tonight. I got the forward spars cut out of 1/8" 5 layer plywood, but I have stalled on the rib slots. The micro-table saw I have cuts a kerf of 3/32" and the ribs are 1/16", so there is too much slop for me. I need to find a different way to cut the slots, or find a thinner blade, so this could be a couple of days before I get the spar slots cut.
Here are some pictures:
