This is a pain. First I had to work to hike in the bottom skin a bit with the dremel to try to get the landing gear bracket to fit. Then it still took a good amount of coercing with a mallet to get it in place. The. Try to temporarily install enough bolts before I match drill the remaining holes. Could get those to line up. Finally ground the threads off an AN4 bolt and used it as a drift pin and got it started. Then was able to install the other bolts. Very difficult to get my hand between the spars to install the nuts but finally figured how to reach the from the end. Got the hardware all temporarily snugged up. It does seem that the AN4-14s are too short. [figured this out - I was using the wrong nuts. Too bad I already ordered new bolts.] Got the drill templates cleco'd in place and match drilled the #30 holes, then upsized to 1/4”. Now I need to take it all back apart. Not looking forward to it. 7/9: was able to remove the aluminum doubler and get it deburred. And was able to get the steel weldment deburred in place. I gave up on trying to remove it. Was able to rivet the skin diuble in place with the weldment in place. Then installed all the bolts, with the correct nuts, and tightened. Needed someone with little hands to get a wrench in the in board bottom nuts. Right gear mount is done. Hopefully the left one goes a little more smoothly, but this really wasn't bad.
