Really could not do much today, lots of other projects and committments. But I was able to reinforce the slosh rib, and cut the left wing fuel cap hole. Cutting a 2 1/2 inch hole in a perfectly good wing skin was a leap of faith, but what the heck? That's what the plans call for. I'm not thrilled with the fuel caps, but the next grade up seems to be almost $200.00 per cap, and for that, I can do with what's supplied in the kit.
4 1/2 inch cutout of the inside bid.
