Hi list,



How difficult is it to get the wing lined up and pinned to the fuselage?



I had this idea that two people could lift the root while a third slips the first pin in.  Then we could lift the tip/pivot the wing around the pin until the upper holes line up.



Or is this more complex than I'm thinking?



Thanks for the advice!

I have had to do his twice. Each time it was remarkably easy. First off, I put my bolts into dry ice overnight to shrink them slightly. 



Then I used two of these lifts (https://www.princessauto.com/en/detail/300-lb-dirt-bike-motorcycle-lift/A-p8667792e) that a friend had on hand. One at the wing tip and one at the root so I could tweak the wing angle.



As you suggest, I got one bolt in and the rest soon followed. I think it will be awkward to do it manually as it may be tricky to keep things steady.



Cheers

Ideally, if you can round up three others to help, I'd put one each at the leading and trailing edge of the root, one at the tip, and one to slip in the bolts.  They won't need a lot of force.  Using a round-nosed "bullet" helps line things up.  As Les said, the first one is trickiest, then they get easier.

It’s easiest with 4 people,  it you could do it with 3. Have one at the wingtip and two at the wing root, one in front and one behind the wing. The one at the back will need a screwdriver or something to spread the rear spar carry-through so the rear space can fit into the slot. While holding the front of the wing, the person in front or behind can sight through a bolt hole to verify alignment, then the other person can put the bolt in place and tap it in. The person at the wingtip will adjust his position to help alignment. Once one bolt is in place on top, then the person at the wingtip will move up or down as necessary to get a hole at the bottom to line up, then tap another bolt in place. Make sure to grease the bolt before inserting. It will help them go in and come back out when necessary. You can clean any grease from the threads for final installation. Once 2 bolts are in place the rest will be much easier. I like to use a 2x2 long enough to hit with a mallet in front of the front tank baffle so I don’t risk hitting the wing or the fuselage. Make sure any fittings in the tank area don’t get in the way of the bolts. It can happen easily.

I used my rivet gun to tap them in.

I found with pilot bolts that my spar web holes did not line up on left wing with the holes in the square spar caps. (IOW the bolts wouldn't go through wing spar by itself without the carry through. Vans advised me to carefully use Dremel on back side of the web to enlarge web holes only to match, and even though I had the right size reamer to NOT use the reamer from the front side as it might remove material from the spar caps.



Used dry ice, LPS1 and drift pins with dead blow rubber mallet to get mine in.
