 |

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.

I did the first wing mounting as you describe using hardware store bolts. I
did put in the standard 1/4" bolts as well but without nuts just to make
sure all the holes lined up. This was pretty easy.
I took the plane down at the 2 year point to paint, and removed the wings in
the process (way too hard to paint the bottom of the wings while on the
airplane). While it was not a piece of cake to get the wing bolts out, it
wasn't impossible. Getting them out however did take a variety of tools,
wood blocks, and cursing. I used new nuts when I put the wings back on.
BTW - I recommend waiting for paint until after you have a flying machine.
I made several changes the first two years that would have made a mess out
of a nice paint job.

I used tapered hardware bolts to set the initial alignment, then regular hardware bolts and nuts to attach. One critical step – have someone lift the wingtip to adjust the dihedral to take pressure off the bolts – both during installation and removal.
I attached the wings, set the angles, drilled the holes, drilled the fairings, fiddled with the ailerons, fiddled with the fuel lines and wing wiring – then removed and stored the wings. Will reattach with the real bolts after canopy, skirts, baffles, wiring, top skin, gear fairings and various unknown unknowns are completed.

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!

Good rundown Booger.
My wings should ship next week. Finished the tail last night. Not real
proud of the look. Profound new respect for Rosie the Riveter. But,
stuff lines up and that's the part bondo can't fix. LOL
Did you make the Ranch Roundup? I hung with Tom Morgenfeld and Jimmy
Doolittle but missed you. Sorry bout that.
