Going to use actual Stearman sumps. I have not decided yet if I will cut off partof the flanges and have them welded on or use bolts and proseal. (Stearmantanks do it both ways.)--------Jake Schultz - curator,Newport Way Air Museum (OK, it's just my home)Read this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/2_su ... ___Subject: Pietenpol-List: aluminum welding troubles

I think if truth be known, the problem lies with the welder, not the machine. Too thick for the machine, maybe. I tig machine provides a very precise and incredibly fast heat source. I'vewelded Nixon marine exhausts with the same machine as I welded an aluminum tunacan.

Jake I planned on doing the same bur couldn't make the sump fit properly closeto the edge. So I just machined one from aluminum. Can share a pic upon my returnfrom Florida.

You need to find another welder and now you know the questions to ask upfront. Your tank should not be a problem.Barry NX973BP-----Original Message-----

We got back from CC#32 and found a very nice new issue of the newsletter in themailbox. Special thanks to Dowe, Ken and all the others who made material contributionsto it. Andy, welcome aboard. While I have made a lot of comments about not waiting, Iam mostly speaking of the people who will get started 'some day.' As pointed outby others, some patience and understanding goes a long way in traditional homebuilding.The key to not 'waiting' once you have gotten started is to findways to make effective progress when waiting on one element. My actual goldenrule of homebuilding is "Persistence Pays." Your project will present at least1,000 opportunities to call it quits. To finish, all you have to do is masterthe phrase "I can always quit tomorrow" and keep chugging along. Even when the newsletter is set to 'High Blower' it still only comes out every120 days. If you are thirsty, consider ordering a set of back issues direct fromDoc and Dee. You will have a large pile of timeless content, and they are agood way to get to know a bit about many of the most prolific contributors here.-ww.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: aluminum welding troubles

As Ken and Barry pointed out, .050" is plenty thick for anyone who knows what theyare doing to weld. So is .040". If you tour the Zenith factory you can seecountless leak free wing tanks welded from .025", all done with normal Tig machines,by mortals.Keep in mind: Never weld mounting tabs on the tank, always use straps to mountit - Try to avoid any butt weld on a tank - If you are having a welder do it foryou (good idea) bring him a pound of 1/16" 4043 rods so he isn't tempted tojust try the rods he has laying around. I have welded about 150 Corvair oil pans from .050". If you would like to see whatthe welds look like, here is an 11 year old story with good pictures.http://www.flycorvair.com/601March2004.html -ww.Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________
