Subject: Pietenpol-List: aileron nut plates, Mike, I simply wood screwed my nutplate 'ears' into the wood using a dab of epoxy in the holesafter the initial 'dry' installation was complete. I used small countersunk head machinescrews in my alum. piano hinge to match the nutplate threads. Floating nutplatesare more forgiving for fastener/screw alignment but the fixed one are a bit cheaper I believe and workfine too. No need to over-do the spacing on your aileron anchor points. I believe I haveabout 7 ea. per hinge faces. Mike C. ________________________________________________________________________________

Mark,I'm finishing my C-85 powered GN-1 -- about to cover the fuselage (doug fir). My main caution to you would be to take a close look at the example weight and balance in the plans. Although it is incorrectly done, you can use the example weights to do the calculations properly. You'll find a far aft c.g. (I think it is almost 35%) I did a preliminary weighing on mine with the wings simulated by weights and found the same far aft c.g. Now my J-3 mount has to go. I have to build a new mount at least six inches longer. Maybe the steel fuselage will be different, but just be aware before buying a motor mount and cowling. Feel free to PM.Tom BernieGloucester, Mass.On Jan 30, 2009, at 1:50 PM, Mark Baxter wrote:> >>> Greetings all,> This is my first post but I have been following along for several > months.

Thanks for the replies I'm TIG welding so will head out to buy a gas torch to heatthem up.Do I also need to heat the welds as well or is it ok that thay have cooled slowlyanyway?ThanksCarsonRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

MikeDon't know if you had this problem.I used the floating nut plates where the threaded barrel is slightly squeezed to keep screw from working loose.I found that in order to screw the screw into the plate, lots of force was needed. too much twisting force for the wood screws to hold.Lucky I found this out before assy. The nut plate would have torn out inside the covered wing.I had to run a tap through the nutplate, Kind of defeating the perpose of the crush, but allowing the smooth assy . Then used loc-tite on the threadswalt evansNX140DL----- Original Message -----
