Making an Alu fuel tank
 

Out of interest - has anyone tried using this stuff -

I've seen it demonstrated at a few trade shows and it seems far to easy to to use! Never really paid much attention to it before as I rarely deal with steel but with the prospect of needing a fuel tank they could be quite useful if they actually work!

to be quite honest only a mad man would use that stuff on a fuel tank. i can see issues with the metals expanding at different rates and cracks forming.

MK-Engineering will do you a proper ali welded tank for £80. why take the risk?

I too have seen it a various trade shows David & like you, did not take too good a look, just thought to myself ........" Yet another wonder product " :rolleyes: :D

Being the eternal pessimist that I am. My gut instinct tells me that a weld made at such a low temp will not be suitable for a potential high stess app ;)

If you have a decent heat source availalable, I would stick to the more traditional filler rod & flux route.

I would love to be proved wrong........... Like I said......I have seen the product but never used it :)

Ash, is that their going rate, or did you manage mates rates because of the magazine article?

I e-mailed martin this week and was quoted £125 delivered for an injection tank.

Cheers

i wasnt aware that i was getting mates rates. i certainly didnt ask for mates rates.

I wasn't inferring that you did, just wondered if he might have done a better price because of the mag??

Maybe you should have, it might have been £50;)

Well I do like to throw a few wild ones out in the mix. These aluminium brazing products seem very interesting. Doing a bit of research - it seems they have been used quite succesfully to build intake manifolds - quite impressive really when you consider the weight hung on them. Looking round a bit further, over on the mig welding forums, there is an example there of using it to fix a pipe into a plate that is subject to 28 inches of vacuum!

Having spent a bit of time making boilers that were silver soldered together, this seems like quite a similar process to me - but made to suit aluminium.
