The right side gear leg has been a bear to fit to the gear tower. I wasn't able to get it to insert all of the way into the weldment, so I thought I'd just pull it out, figure out what was binding, then put it back in to ream the matching holes. That simple act of "just pulling it out" ended up being quite the ordeal. I tried and tried, but I couldn't get it to budge no matter what I did. Finally, with a couple of people helping, we got it out. I had to clamp the weldment to the bench, have two people standing on the bench to keep it from moving, heat up the weldment, put a pipe in the axle for leverage to twist, then hit the upper end of the leg with my rivet gun while twisting the axle. That popped it out. It turns out the powder coating on the leg extended about 1/4" to far up the leg and was jamming into the weldment. I filed off the excess powder coating, and with that the leg slipped right into place. I reamed the holes in the weldment and leg and then stored the leg for later.
The gear weldment gets bolted to the bulkhead (the wing spar carry through) next. No matter what I did, the weldment would not sit flat against the bulkhead. The outboard section stuck up about 1/8".
The weldment itself has a bit of a bow to it, but part of the problem with it not fitting against the bulkhead was also that the weld on the back side stuck way out beyond flush. I took a file to the weld to knock it down.
With that, the gear tower fit relatively well. The bow in it still made it stick out from the bulkhead a bit, but it was close enough that it should be fine once the wing spar bolts go in.
The bolts that attach the weldment to the bulkhead are really difficult to get a wrench on, let alone a torque wrench. For the upper bolts, I used a wrench on the end of my torque wrench (with the appropriate calculations to compensate for the additional length). For the lower bolts, there was no way to get the torque wrench on the nut side, so I had to torque from the bolt head side. That's not ideal, but there is no other way to do it.
