I didn't think about how to keep the epoxy from sticking to the spar spacers I have in place. Guess I'll have to figure out a way to get some wax paper in there. I soaked the first 15" of the top cap strip in hot water for about 20 minutes and clamped it in my former. Seemed to work OK. So even though I'll staple the gussets on I should wait for 24 hours or so before removing the rib to do the other side? Thanks for all the help and encouragement.

Just wax up the spar insert pieces (or anything else you don't want epoxy to stick to....) real good. Epoxy won't stick to wax. You may have to do it the first few times but after a while it will have enough wax embedded that epoxy won't stick to it....ever. I've used paste car wax in the past for epoxy laminations and hollow core wing molds and it worked fine. If you have a composites products store available you can get this stuff called "mold release" which is also just basically wax. Easier (which I like since I'm lazy) than fiddling around with wax paper, etc. jm -----Original Message----- >From: JGriff >Sent: Sep 4, 2010 8:21 AM >To: pietenpol-list@matronics.com >Subject: Pietenpol-List: Re: Started my rib jig today > > >The jig has a layer of 3 mil mylar so hopefully that will be OK.

Mine is an aluminum mesh acquired from an art supply house. I've added this antenna article also. My understanding is that you don't have to ground the groundplane to anything else. It IS the " ground " . The coax from the radio is attached to the groundplane. The only concern I have with mine is how it will be affected by the control cabling when I finaly get the thing in the air. Clif oo.com> > > This is good information. I like the idea of an internal ground plane she et even if it isn't too big. I am guessing it needs to be grounded to the n egative battery terminal since it's mounted in a wood fuselage? or maybe on ly the radio grounding from the antenna coax? probably wouldn't matter for the ELT but might with a radio antenna as far as interference. =0A=0A=0A ________________________________ Message 8 _____________________________________ Time: 10:10:29 AM PST US Subject: Pietenpol-List: Re: Try some paste wax....

From: "kevinpurtee" You'll want to thoroughly clean the wax off the completed rib before gluing to the spar. If the rib won't stick to the jig it won't stick to the spar. I think I might have used varnish on the that spot on the jib?

From: "Billy McCaskill" Real mold release agent is made from PVA (poly-vinyl acetate) and contains no wax.

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 plywood I 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 the adhessive, and are very heavy (i used epoxy). Then I try with 2 sheets of wood and fiberglas in the middle... it look fin, and a last option with only three layers of fiberglass. The one with wood is very strong, the sandwich of wood and fiberglas is ok, and the fiberglass only it is a little soft in bending (my english is very shot as you 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 how hard 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 gussets do in the rib. Thank you, best regards. mario Read this topic online here: http://forums.matronics.com/viewtopic.php?p=311402#311402 ________________________________ Message 14 ____________________________________ Time: 08:19:20 PM PST US From: "Chris" Subject: RE: Pietenpol-List: Re: leading edge covering No, do not support the rear edge of the plywood.

It will be more expensive buying it this way than buying full sheets, but if full sheets are not available then this might be your only option for getting the 1.5mm plywood. 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 McCaskill Urbana, IL tail section almost done, starting on ribs soon Read this topic online here: http://forums.matronics.com/viewtopic.php?p=311408#311408 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message pietenpol-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Pietenpol-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/pietenpol-list Browse Digests http://www.matronics.com/digest/pietenpol-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
