Can I have some advice please.I was reading thru the archives and read a post which said it wasn'tnecessary to bolt the leading edge to the ribs (as per plans) because of thestrength of modern glues such as T88 or West Systems.Is gluing together with ply or alum LE cover sufficient?I am using West Systems and intend to cover the top and bottom of LE withalum attached with epoxy and screws.What did others do?Thankyou,JohnW-- ________________________________________________________________________________

On NX18235 the leading edge is glued and bolted to the ribs. 1/16 plywood is attached to the ribs with T88.Bolting the leading edge to the ribs is prudent.Greg Cardinal----- Original Message -----

Subject: Re: Pietenpol-List: Attaching Leading Edge to RibFolks,I used small #10 machine screws and nuts to hold the leading edge to the ribs. Even if you don't need them for strength, they are nice to have to insurepositive placement until the glue dries.Dan HelsperPoplar Grove, IL.________________________________________________________________________________

RobIn my opinion, the stringers are the place it is most necessary to use the tapes. Dick N. ----- Original Message -----

The mechanical fasteners are a good backupif you get a bird strike. Pietenpol's don't always take bird strikes from therear !! Keep in mind that Aluminum expands and contracts much different rate than wood, which might be a factor when it's sitting out under thesun on a Hot day. I don't think you need anything on the bottom of the leading edge...that's just extra time, effort, and weight.Chuck G.NX770CG________________________________________________________________________________Date: Sat, 16 Dec 2006 17:08:21 -0500

Thanks for the advice folks.I'll stick to the plans but will use 1/16 ply instead of cardboard on thetop only.Walt,I do have a mantra (while I'm meditating in front of the plans).....Keep it light, stick to the plans. Keep it light, stick to the plans....But no doubt I'll be asking some more questions with obviousanswers....Follow the plans....JohnW-----Original Message-----

Another thing I noticed is that the wing really stiffens up once the leading edgeply is glued to the leading edge and to the ribs. Many things on the planswork together and serve more purposes than just what might be first apparent.Don EmchNX899DERead this topic online here:http://forums.matronics.com/viewtopic.p ... __________
