Brief Description: a better fixture for rib angle attachment
I stumbled around and found a better way to hold the rib attach angles for drilling. The best approach seemed to be: first, clamp the rib attach angles exactly where you want them to be. this puts the clamps in position to block the bolt hole drilling. then use a couple pieces of spar cap angle next to the rib angles. clamp the rib angles to the spar cap pieces, then clamp the spar cap pieces to the spar. Then the first clamps can be removed, clearing the way to drill the bolt holes.
