Subject: Pietenpol-List: attaching the aluminum to the fuselage sides Hi Richard,I'll jump in prior to Jack to tell you how I attached my instrument cover aluminum. I used cap strip material to hold the fabric off of nuts, bolt heads, and such on all four corners of the fuselage and just screwed my aluminum into the edge treatment with stainless steel truss/Phillips round head screws with thin nylon washers on them so you don't nick up the paint. I didn't know that Frank Pavilga had those brass inserts but he might. When I asked Frank I said 'what happens when you strip one of your wood screws out if you remove, install too many times or over-torque (as some of us....like me, are very prone to doing) and he said you just dip a toothpick in T-88 and stick it in the screw hole, break it off then you've got a fresh thread you can make and not have a loose screw.I personally don't like the idea of putting in brass or other inserts to hold instrument cover aluminum panels in place because you're making Swiss cheese along the whole top longeron and though I'm not an engineer it just doesn't feel good in my gut to know those holes are there. (plus they add weight and expense that you really don't need)I am pretty amazed that with the years passing that none of my screws along those edges has worked out. (course I've never removed the alum. covers for any reason yet either)Mike C.________________________________________________________________________________

Mike I agree. First of all once I get the cowlings final mounted I hope to neverhave to remove them. If the brass wood inserts are used, they do make quitea hole, even for only an 8-32 screw. You also would have to use brass screws tohold on the cowling due to dissimilar metal corrosion. I think I will go yourroute and just use SS wood screws. My Piet is coming along pretty good. This morning I mounted my tailwheel assembly,which I finished welding last night. A few days ago I got in my tubing fromDillsburg for my straight axle gear, so I will be doing that next.
