 |
|
Dear Listers,
I'm planning on trial mounting the wings on the RV-8 this weekend. I want to get the flaps and ailerons rigged as well as get the rear spar drilled. Once that's done, however, I want to take the wings back off for storage.
How hard is this going to be? Will I ever be able to get the bolts back out again after I get them in?
I've heard of people using hardware store bolts for trial fitting. Is this a good idea?
What's the minimum number of bolts I should put in to assure the wings will stay on unsupported and rigid enough to set the incidence?
Realistically, how hard (and how much damage) will taking the bolts back out be?
Thanks for any insight you can lend.

Yes, using hardware bolts works just fine. That's what I did on my RV-7A. I ground the ends of the bolts to give them a taper, greased them, then slid them in when the holes were lined up. They went in easy, held the wings in the right position to do the work needed, then with a little lift on the tips, were easy to drive out. You DO NOT want to use your close tolerance bolts and expect to ever get them out again.

Dear Matt,
I have a friend who is a 4 time RV builder so far. I'm just working on
number one right now. His approach is to mount the wings when they are
ready to be mounted in final construction. Just one time.
I know Van's construction manual has them mounted and removed, but that is a
lot of work that will only have to be repeated
when you finally put all this together. Obviously you have to do what is
comfortable for you. I will take my buddy's approach
which has served him well on four aircraft so far. That's the beauty of
doing it yourself.
Happy building,
John Brunke

That is my plan as well. I will have done everything I can to the fuselage prior to mounting the wings and gear. They will get in the way of the vast amount of work to be done in and around the cockpit. I am only a first time RV-7 builder so maybe there is something I don't know that Vans knows C but so far see no really good reason to have to put them on C then take them off and put them on again later. Too much extra work for now real gain in the construction process that I can see. A good friend of mine used this method on his RV-6 and it worked great. He did everything at home in his garage so didn't need the wide space until he moved the project to a hangar C then put the wings on one time only.

I want to thank everyone for the help on mounting the wings. The mounting went without a hitch today. The hardware store bolts just slipped right in with no problem. Highly recommend. I would say that they will be very useful in the initial alignment prior to inserting the close-tolerance bolts too.
Once the wings were on, I just had to put all the other stuff on the plane to get an idea of what it looked like. Awesome! I thought I'd share a couple of pictures... Yahoo!
Thanks again!

Matt,
Nice job - it's beginning to look like a real airplane. I have to admire a
guy that has a choice of engines setting in his shop.

Matt,
I would recommend the hardware store bolt approach - the precision bolts
will be difficult to remove (impossible in the case of some of them on a
7A due to landing gear weldment). I think I used two per side of the
large variety - one top and one bottom. I don't have experience with the
8 install but just make sure you'll be able to get a punch on the back
end of the bolt to drive it back out - if access is better on one side
than the other I would orient the bolt to take advantage of this fact -
orientation doesn't matter until they go on for the last time....hope
this helps.
Regards,
Joe
