Because my wing skins were not yet riveted in place, I removed the ribs and used what I'd call a "pounder." to set the rivets. It worked perfectly--until I got sloppy with the hammer and dinged my spar web. After that, I used a piece of plywood to protect the spar against my clumsiness. The borrowed pounder that I used is very similar to pounding on an arbor press as suggested by Tony Bingelis Metal Spar Assembly Tips, Sport Aviation, May 1993 Which can be found in the EAA site member's only area. If you check my kitlog site, you'll see how I set the rivets. If you cannot take your wing apart I think that a 4X or 5X gun is required to set the rivets. I bought a 7# bucking bar from http://www.clearairtools.com/index.php?main_page=product_info&cPath=4&products_id=93 but ultimately used the pounder, instead. Also, I concluded that the Zenair supplied rivets were too short to produce shop head that met spec, so I used longer rivets purchased from Spruce. My guess is that joints using the Zenair supplied rivets (with shop heads that are either too small diameter or too flat, take your choice) would be strong enough, but I was more comfortable making sure that my rivets met mil specs.

I finished my upgrade this past April with about 320 hours on the airframe. We experienc ed simila rissues initially. We ended up using about 8 pound bucking bar a nd a 3x gun. My RV friend used the gun and I was on bucking bar. It still took a lot of effort but we did get the rivets in spec even if some of the heads were not as pretty as I'd like. I've got about 40 hours on the upgrade and all is well-----definitely fee l more solid.

This doesn't apply if you are doing this on partially assembled wings. At the suggestion of my EAA tech counsoler, here's what I did, and they came out perfectly. I used the 1 ton arbor press from Harbor Freight ($50) which my counselor loaned me. I drilled the "table" to accept the rivet "cup". Polish is the bottom of the press. Lay the spar on over the table with the rivet head down in the "cup". Lower the press down onto the rive and apply about as much pressure as you can and then hit with a sledge. I used a 4 pounder. It takes 4 or 5 blows per rivet. I screwed up two when I got in a hurry, but all the rest came out perfectly. I'd say for someone with no experience, the is the cheapest and most foolproof way to set these rivets. Oh, I also bought a 1/4lb of 1" rivets and a rivet cutter from ACS and used these for practice on Home Depot aluminum until I was confident in the process.

I used AN4 (mostly -11 but some -12) bolts where the 3/16 rivets were and AN3 bolts where the smaller rivets were (Maybe AN3-11 but I'm not positive). The bolts went pretty well. I realized the rivet holes made by Zenair were much too oversized to use the same size bolts as the rivets so I increased all of them one notch. The biggest problem was drilling and reaming the holes where a drill wouldn't fit. I used a flexible extension for the drill and found the extension would last if I used very small increments on the drill size until reaching the final size. Those holes I could ream without interference I did with a chucking reamer. The rest I just used the right size drill and didn't worry about the perfection of the hole interior Good luck, Paul ready to close up second wing upgrade.
