    Thanks so much for gettin’ back JimChuk!
    The manual that came with the kit, just says “Avidflyer”. It simply says, glue ‘em on! Everything in that manual is hand drawn. I am using the Mark IV manual that I downloaded and printed off of the forum. It’s a lot more detailed. The picture, R2-1 isn’t clear on my copy and looking back in here, it’s not clear either. Sure wish I had an original!

    Hi guys,
    I'm ready to glue the trailing edge ribs. Can anyone explain what they’re talking about the clamping of a 3/8” block?

    Hey Barry, do you still have that tail wheel spring? I have a Model C with a Maule tail wheel. I’m talking about the main spring from the fuselage to the wheel. I don’t have my project here, but I think it’s a metal strap about 1 1/4” wide. I moved my project a while back and I can’t find mine anywhere. Yours might work. Might be interested in the spinner too.

    I just reinforced my rib tails. You can see that I removed the cap strip immediately above the web of the rib. The lamentations of the wood provided a great depth gauge. Dremel with a rotary file for the edges then a grinding blade did the trick. I then ground down one side of a 3/16” X 7” titanium rod, epoxied it in the gouge extending to the end. I had fabricated aluminum by bending it in a “U” shape. I used a brake to bend it past 90, then put a rod on the bend and completed the “U” in a vise. It was fairly thin, not real sure about the gauge. My buddy had it leftover from his Titan. Making it slightly oversized, after the glue dries I’ll profile it to match. If a truck hits it it’ll probably fail, otherwise it ought to be pretty stout.

    Need a little advice. I’m ready to install the wing tanks. My original plan is to Hysol them in and use enough to feather the profile to the spars. Afterward they’ll be wrapped with fiberglass. To even the tank surfaces to the butt rib on the fuselage, resin with glass shards will be used. My buddy suggested to use the same to blend in the tanks with the spars. Also could you tell me what’s the best degreaser for glueing. A degreaser came with the kit. I can’t identify it by smell.
    Whadda think?

    Hey fly wise! Just heard from Dave at TriMas. Evidentially, they do not make a fastener 1/8” dia. 5/32” is the smallest. There’s got to be a way to pop this rivet! Anybody who has ever built an Avid has run into this. How the hell is it done?

    Look at Barnstormers. Search ads, write in Avid parts. The ad says wing tanks.

    Fly wise, you’re an engineer aren’t you! I have a call in to Peerless Aerospace for Visu-look fasteners. Hopefully they’ll have a cross-reference the rivot. Still waiting to here back. Got their name from TriMas who makes them. Thanks!
    Has anyone ever dissected a fiberglass fuel tank, 14gal? The tank end which butts to the fuselage needs some profiling work for a good tight fit. One is sunken in the middle where I would need to build up or take down the corners. The other is a good 1/4” out of square. How thick are the ends? Can I sand them to fit? I’m guessing they are an 1” thick.

    Who do you deal with to get those Jo bolts? I looked at Hanson Rivet, but didn’t see a contact number. I have no idea how to cross reference a SS43FS rivet.

    Thank you very much for your reply. I Googled Jo bolts and I guess and would have to buy the whole shebang tool and all for 2 rivets. Did you buy the kit? I saw $490, rivets were about $2.50 apiece.

    Hey guys,
    I was hoping to hear from someone in regard to my questions of applying glue to the stiffeners or not. In my opinion, for what that’s worth, I don’ feel they can move when the strut attachment is riveted. I do have a good snug fit on the inside of the spars. The instructions say nothing about glueing them. Ed did mention it though. Also, I haven’t figured out how to get that rivet under the clip. Can’t get the rivet gun in there to pop the rivet. 
    With the spar attachments clecoed in place, I did go ahead connected the wings to the fuselage. Plumb bobs/string line on the leading edge and triangulation from the tips to the tail prove I got a good result. I did this with the wing tanks in place on a dry fit. When glueing the ribs to the spars the washout was set to 3/4”. It was mentioned that the tanks were made with a twist to allow for washout. They do. At the time, didn’t think it would be a problem, but the spars do have a bind. Not bad, but a bind. The left strut was made at the factory to be adjustable and the right was not. I did modify the right strut to match. The adjustment will hold the bind, but to relieve it somewhat, the washout will increase to a 1 1/4”, the book called for 2”. I am pretty sure I’ll have to modify the jury struts too.
    I’m heading out to clean the fuel tanks with 1 gal acetone:1 gal AV gas. After sloshing it around we’ll leak check and further flush by filling them up with fuel. 
    I would appreciate guidance anyone can offer.

    Howdy guys!
    Decided not to coat the tanks. They tested fine.
    I have a couple of questions:
    1st: To secure the wooden spar stiffener, do you reach inside the spar with epoxy on a stick or just depend on the rivets on the centerline of the strut attachment.

    2nd: How can you pop the rivet behind the clip on the strut attachments?

    Hi guys! Gonna get back to work on the wings after a long absence. We’ve relocated the project.  How do you guys feel about the fiberglass fuel tanks? Issues?

    Thanks TJ! I thought that might be the best way.
