Pietenpol-List: Gussets

Post by matronics »

Original Posted By: "Chris"
Hello,May be you just talk about gussets, but I do not find anything so I want you toask and talk about them.Th problem with the gussets begun because I we don't have plywood in 1.5 mm ( 1/16") here where I leave. I begun with the wing ribs but the minimun plywoodI have is 3 mm and I do not like it, it is so so...So I thought in make mine on replace for the gussets. I started with wood sheets(3), but is very difficult to make becuase it bends too much when I put theadhessive, and are very heavy (i used epoxy). Then I try with 2 sheets of woodand fiberglas in the middle... it look fin, and a last option with only threelayers of fiberglass.The one with wood is very strong, the sandwich of wood and fiberglas is ok, andthe fiberglass only it is a little soft in bending (my english is very shot asyou can see).Reading and googleing I find some articles where talk about even "paper" gussets,so I have a big question and is "what are the gussets for (I suspect) ad howhard have they be, in tension, compression, bending". What do you recommend?May be I can use the 3mm plywood ?.. I want to understand the job the gussetsdo in the rib.Thank you, best regards.marioRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Hi Mario,If there is a hobby shop near you which sells radio control model airplanes andsupplies, 1.5mm plywood should be available there in smaller sheets. It willbe more expensive buying it this way than buying full sheets, but if full sheetsare not available then this might be your only option for getting the 1.5mmplywood. The 3mm ply will add a LOT of additional weight to your wing ribs,as there are a lot of gussets on each rib and there are 30 ribs to build...--------Billy McCaskillUrbana, ILtail section almost done, starting on ribs soonRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Gussets

Hello Mario,There are also several sources on line.This one currently on ebay: item number: 15048268181$23USD for approx. 18 sq/ft 1.5mm hobby plywood. This is about the same price asAircraft Spruce & Specialty; approx. $25 for 20 sq/ft. (according to my calculations.I personally purchased from ACS for the convenience and reliability.As with everything, shipping is a factor, but I would check into it.Good luck,SteveOwings, MD--------Stevewww.mypiet.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Sun, 5 Sep 2010 09:59:43 -0700 (PDT)
