This makes a much stronger joint than just butt-welding two pieces of aluminum. I turned my flanges to the outside, which resulted in slightly less capacity but was easier to rivet. I think next time I would build mine like Jack Textor did. As Jack did, I riveted my tank together, then TIG welded all the seams and all the rivets. Then I pressurized it with the system you see in the last photo and painted all the seams and rivets with soapy water. I had 37 leaks. Re-welded it and had 9 leaks. Re-welded it again and it has never leaked a drop since.

Welded joints often leak, bends don't. 5052-H32 is a good, all-purpose alloy, with decent strength, good bendability, and good welding characteristics. It is the "go to" alloy in the shop where I work. In the case of .040" thickness, you should be able to successfully bend very sharply without risking cracking. Do a few test bends to make sure first. If necessary, introduce a slight radius into the bend. Bill C.

Also are you suggesting I bend a flange for all the joints to facilitate the welding as opposed to a butt j oint? - My tank will be a nose tank and I am trying to get as much capacity out of it as I can. So, right now, the template-is quite the odd shape. Anyhoo, I'll pay attention to the proper bending techniques and bend what I can.

You will notice in subsequent pictures the color had changed to that of 5052-H32 aluminum. A butt-joint is always the very last choice for a weld. It is the weakest possible joint, and has virtually no resistance to cracking due to vibration. Only weld a butt joint if there is no way to do a better one, and plan for it to fail. Jack Phillips NX899JP Smith Mountain Lake, Virginia _____ From: owner-pietenpol-list-server@matronics.com [mailto:owner-pietenpol-list-server@matronics.com] On Behalf Of Michael Perez Sent: Thursday, October 20, 2011 2:49 PM Subject: Re: Pietenpol-List: Re: Bending 5052 Fuel Tank Thanks guys. Jack P., why the "color" inside your tank? Also are you suggesting I bend a flange for all the joints to facilitate the welding as opposed to a butt joint? My tank will be a nose tank and I am trying to get as much capacity out of it as I can. So, right now, the template is quite the odd shape. Anyhoo, I'll pay attention to the proper bending techniques and bend what I can.

Definitely take the advise of someone, think it was Bill to cut out any ply aft of the pilot seat not glued to spruce or that looks like a gusset. Looking at your first picture, I think you have a Cub engine mount. My Grega has that mount and it makes it harder to get the w/b to come out and also makes it real hard to safety the oil screen. The Cub mount puts the bottom mounting flange of the A65 only about 7" from the firewall, Pietenpol plans put the flange about 11". The engine mount jig I borrowed from D Emch puts the flange about 12.5". Since your plane is not covered or assembled I would consider using Pietenpol's cabane to wing spar attach brackets, which would allow you to move the wing aft if it would help the w/b. I am flying a Grega and building a Piet. I live at Hales Landing WV(2WV3) which is just across OH from you. It takes me about 2.5 hours to fly the Piet(Grega) to Waynesville, so it should be about 1.5 hours for your 601 if you wanted to check out the Grega or Piet project.
