m>Hi all...I have asked Mike Cuy if he would mind if I put out a request to see if anyone has a video tape, not DVD, version of his Pietenpol build. Im in Australia and the DVD that Mike now has wont work on our DVD players here. I have a dual Tape and DVD player which plays the US format tapes so if I could borrow a tape copy I could burn a DVD in PAL format for me and send a copy to Mike for future use. I WILL NOT sell any copies this is purely for my use only and of course will return the tape to the owner once done.Regards Scotty--------ScottyTamworth, AustraliaBuilding a Corvair Powered Pietenpol Air Camperwww.scottyspietenpol.comRudder, Vert stab, Elevators and 8 Ribs built...Read this topic online here:http://forums.matronics.com/viewtopic.p ... 8#337078le, List Admin.________________________________________________________________________________Subject: Pietenpol-List: Re: tips for welding fuel tank filler neck flange

Original Posted By: jorge lizarraga
I'm doing my third fuel tank (don't ask.) and have always struggled withwelding on the filler neck ring without causing lots of distortion on thetop of the tank.The first time, I built the tank and then cut the hole and welded on theneck flange and it warped the snot out of the top and just didn't look good.The second time I welded the flange on to the top while it was flat, priorto welding it onto the rest of the tank. That worked MUCH better, but wasstill not as clean and smooth as I see on others tanks.So. any suggestions for how to do it and avoid warpage from the heat? I tigweld by the way.My plan is to rivet the flange on, weld the bead around the edge and thenweld over the rivet holes hoping that'll keep things smoother.Thanks, as always.Douwe________________________________________________________________________________Date: Fri, 15 Apr 2011 22:13:34 -0700 (PDT)

I'm no welder, but I did stay at a Holiday Inn Express once... ;)I presume that you are not trying to weld around the entire perimeter in one continuouspass and that you are welding small segments not directly adjacent toeach other?Would it be possible to fill the tank with water while you're welding it to helpabsorb the heat and minimize the distortion? Or perhaps just drape some damprags around the filler neck while you're welding it? I'm not sure what othersteps could be used to help with this, but as I said I'm no welder. I'm surethat others will have more advice than I can offer, but hope this is of somehelp to you.--------Billy McCaskillUrbana, ILtail section almost done, starting on ribs soonRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Douwe,Have you considered Proseal (can't remember the new name) and rivets? It hasworked well for me. I wouldn't be comfortable with ANY moisture around mytig machine.JackDSM _____
