Guys,

I'm in the final assembly of an RV-9A. Any ideas how to get the nuts on the lower outside NAS bolts?
Did anyone remove the lower brake line fitting in the area for better access? I've got a few threads of the NAS bolt exposed beyond the landing gear weldment to gain a little more clearance for the nut.

It also looks like I will have to jam a screw driver under the nut to keep it from turning when I tightening it - there is no room for a wrench.

Anyone have an access hole on the side of the fuselage - I know this is extreme.

Any ideas appreciated...

I had to bend up and grind an open end wrench (buy a cheap one from Harbor Freight) to get to that tight spot.

You have to put the nuts in place before the bolts come through. I use a pair of needle nose vise grips to hold the nut, then as I turned the bolt, the vise grips would jame against the weldment. I torqued the bolt rather than the nut on the bottom row.

I don't know if I would make any adjustments to the holes at all. The close tolerance bolts are supposed to be very tight. I don't believe Van's would endorse a reamer on the holes at all.  I used the rivet gun set on very low psi to encourage them in. I also put the bolts in the freezer overnight although I'm not convinced that really does anything. Another person wiggling the wings doesn't hurt either.

Thanks for the info Bob.  I've also gotten several direct responses on the issue.  I'll send pictures when I get the last bolts installed.  I've had to use a mallet to drive the bolts.  Knowing this I would have used a reamer on the center section spar carry-thru before I built up the fuselage. 
 
I've also learned the two nut plates on the wing spar stubs are worthless.  The is so much resistance on the AN4 bolts that the nut plates threads are stripped by the time the bolts are secure.  A better solution would have been to use nuts instead.  These can be easily reached by leaving off the wing tanks when the wings are installed.
 
Thanks again for your ideas and experience...
