Your thoughts? |
I don't think.....
....that the washers are there for that reason, Webb. You don't want a bunch of extra threads sticking out the other side. The bolts can get galled by rotating inside the attach fittings, is what I meant. I looked at drawing 11 and also the -7A that's being built here. Looks like it might take a ground down socket to get on the nuts of the 8 larger bolts. By all means rotate the bolts if you positively cannot turn the nuts.

Dry Ice Technique
I might have missed it but I didn't see Dry Ice being mentioned anywhere in the posts. We used this technique on my dad's RV-7A when installing the wings for the final time at the airport. Put them in the freezer the night before and then took them to the airport on ice in a cooler. At the airport put at least 90% pure alcohol into a coffee can and added dry ice. The temp. drops to -109.3 degrees F and dropped the bolts in one at a time for a few minutes and installed...slid in with little fuss at all...no cussing required. :)

Boelube.....
....is great stuff, Webb. After it dries, it remains kinda waxy and even assists in getting screws in and out of nutplates. We used it on our spar bolts as well........yeah, a great day when the wings go on!

The lower nuts are a whole lot easier to install if you use MS21042 nuts (available from ACS) instead of the Vans supplied ones.

Serioiusly, after what I've read, I'm not sure it makes a difference as long as you keep it off the threads. Interesting about the MS21042 stop nuts. |
Regarding my post #16 about MS21042 nuts. If you use these nuts on the lower bolts then think a bit first before doing them up with a ring spanner (wrench). I can recall that on one of the nuts I used a ring spanner to hold the nut while turning the bolt and was unable to remove the spanner once the bolt had protruded through the nut due to interference with the main gear weldment. I ended up having to undo it and then using an open ender instead. :o

Bottom Wing Bolts
Has anyone ever tried to put the bottom wing bolt nut that is in the corner just behind the row of 5 bolts that are along the landing gear mount, with those 5 AN3 bolts removed? I was looking at the this the other night and thought that it could perhaps make getting that one bottom nut tighten a little easier. Of course putting those 5 bolts back in with the wing on may not be a piece of cake either.....
Just curious. Paul |
