Joshua's RV-9A Project

Finished drilling and installing all the spar nutplates; just need to countersink the center screw holes now.  Also need to re-make the tiedown bars, as the ones I had made for the old spars don’t match up–the top & bottom attach holes are perfect, but the center pairs of holes–the ones that are in the web, that have the aileron bellcrank brackets on the back side–are off by about 1/3 diameter.  Not wanting to oblong these holes, as they’re on the spar and attach flight control hardware, I have ordered a pair of tiedown brackets from Cleaveland Tool.  Also ordered more clecos (300 3/32″ and 100 1/8″; Brown Tool had a holiday special thru today), as I intend to build both wings simultaneously, and–especially with the longer wing of the -9–more are helpful.  I think I will have a total of 600 3/32″ and 250 1/8″ now.
