Will,

Doesn't matter. Without performing an embarrassing "self-assessment," I may have fallen prey to my "lazy side" - expecting an answer when what I should have done (and later did) was a little research.

I gained much more info, and, more importantly, perspective on the subject as a result.

Finally, the practice gained in exercising "curiosity" sufficient to "do the research" frequently returns rewards great enough to keep me away from my "lazy side" (for awhile anyway, laziness is relentless, isn't it? ).

Isn't it interesting how the "pursuit of happiness" a cardinal factor of Citizenship, has a benefit to metal shaping as well as the rest of what we do!

"Do the math, do the research, and excel!

Onward and upward,

mjb

Fair enough. But just for info, the fillers I use mostly are 2319 for exotic mountain bike frames and so on. 5356 for most applications as it's a good all-rounder for marine grades and castings and 4043 for soft material or to weld hard material that would otherwise crack due to age hardening or temper. Sorry if even this sounds a little vague but it's a big subject.

The melting point of the 6061 -6060 is very low, and is actually right at the melting point of some very good brazing materials - 1040F. Although published information would lead one to beleive that brazing these alloys is not feasible, it is very well done, and is actually accomplished below the solidus of the 6060-6061 parent metal.
(cheering from the crowd)!!!
Hi Kent,

Thanks for the information, now I can make a shopping list and go to the factory.
I've been searching for the fillerrods and both types are available over here, so I can get started.
Evryone, thanks for sharing all the information and have a nice weekend.

Just thought I'd share. Rose made of 5251 ally.

Then painted.

It was given a phosphate wash-coat then a satin powder finish in white before being airbrushed with glass paint then stoved again.

Thanks, Richard. I do quite a few flowers, it's become a hobby. People still aren't used to it, though. After many years of seeing me make all sorts of industrial things they think it a little weird that nowadays I'm often found in a corner making a daffodil. But seriously. Anyone wanting to learn metal shaping should try a flower. It's every skill you'll ever need only on a small scale and if you get it wrong it still looks OK and you can give it to the wife as an apology for all those late nights in the shop.

Will

Default Seagull tank

Hi all,

I promised to put some pictures when I finished my first(gaswelded) tank and it's ready.
To limit the distortion of the sheet when welding the attachments to the sheet I mounted a steel plate
to the other side but it still deformed a little.
Then I bended the sheet over a metal tube. This wasn't going well because the side of the welded attachments were
annealed(first time I discovered in practice)and bended much easier than the other side.Therefore I had to fasten
the sheet to the tubing with clamps and hammered it in to position using a piece of wood wrapped with a newspaper.
This went quite well.
For the two sides I made a sort of template that pushes the sheet in form when tightening it in a vise.This worked
only for the straight ends. The round ones were hammered over the template but got a little wrinkled. I made
the wrinkles smooth with a hammer and a(selfmade) dolly.
After that, tacked it and welded it. I brazed the bung and petrol outlet(thanks Kent)in place and grinded,filed
and polished it.
I'm quite happy with the result but when I am going to make another one I would make the sheet longer to make
bending easier and start grinding with #120 in stead of #80(thanks Paul S) because of the little scratches that
vaguely can be seen.

Turned out really well. I should think you are well pleased with that.
