Subject: Kitfox-List: Was rivnuts now nutplates I bought a Rivnut kit and I tried 6-32 rivnuts and also mounted a 8-32 mini nutplate on a top-rib portion that I have here. The rivnut uses a fairly large hole but I suppose it could work, backed up with aluminum and epoxy it's likely strong enough. It does protrude from the rib on top a lot, they make flush ones I think. I wan't all that enthused about the whole idea. The nutplate on the other hand was an ideal solution. It will fit quite handily in the space provided and you could likely leave out the aluminum strip that gets epoxied to the bottom of the capstrip. I attached it with two 3/32 rivets ( number 95001 from Kitfox) and I don't think it would ever move. The rivets do protrude slightly from the top of the capstrip so some type plastic washer or rubber strip under the skylight might be a good idea, I doubt the wingtip would care. So, I'll be using the nutplates, probably in 6-32 because the holes are smaller and a # 6 truss head screw will be much stronger than an aluminum rivet, #8 would be overkill.

Cut a hole in the panel and fabricated some straps to hold it in, connected to the 12 volt sytem, have pigtails for music input and portable recorder. Anyway, here is catalog the page that has it listed: http://www.rst-engr.com/rst/catalog/intercom.html#2-Place%20Portable%20In tercom%20Kit As an aside I built two of RST's headset kits also, works fine with my Delcom handheld.

Every hinge (probably 80 on the maingear door hinges alone), inspection cover, floor board, side panel and even the cowl is held on with screws or bolts backed up with nutplates. It doesn't take long to establish a system even without the fancy tools. What I did was drill the hole, put a bolt in from the bottom and scerw on the nutplane a couple of turns, drill a hole through one wing and drop a rivet into that hole, then drill the other hole. Remove everything and counter sink the holes and assemble in the proper position. For speed, it does help to have a rivet squeezer, but I have used a pair of visegrip type pliers with smoothed and polished jaws at times in tight places. One suggestion would be to get a 100 counter sink and use flat head rivets then no need to add a spacer.
