Assembled the wing jigs discovering the 6mm cup head bolts I bought are crap. They are galvanised, but some will not thread into the nuts, and rotate the base so they won't hold. Resolve to buy hex head bolts and re-fit. Continue using a few 25mm bolts to locate the dead sides.
Started erecting the jigs. Very difficult to manage squareness. Managed to put one up backwards for a while.
Whole bunch of glued up bits.
First jig assembled
Trying to get jig #2 vertical, without knocking over jig #1...
