Can't say i've used em but they won't rust they will be stainless. to get good welds even with tig you need to use a shielding gas on the backside of the weld, critical on thin material otherwise you get oxydisation? basically the backside of the weld will look like a mig or tig weld without any shielding gas.
an excellent welding site for all sorts of info is http://www.weldingtipsandtricks.com/" onclick="window.open(this.href);return false;" rel="nofollow

cheers heaps

i thought it might be cheaper and easier that going to a welder each time i want to modify something

[olddog]

Why not use copper? its easy to silver solder.

[maker]

i would love to use copper
but my still and boiler are stainless already

[olddog]

What type of boiler do you have, is it a keg?

[maker]

yeah just the standard 50ltr keg

why do you ask olddog

[olddog]

I you wish to, I could build you a copper still for the cost of materials, it looks looks you are local so postage should not be a problem.
Just PM me if I can help.

[maker]

very very tempting olddog

thanks for the offer and i will keep it in the back of my mind
if every thing turns to crap

cheers again

[olddog]

What type of still do you have now, and what type of modification do you want to do?

[maker]

i just have a pot still at the moment
but i have been thinking of this design for a while
i will see if i can throw up a few drawings tonight
and you can tell me what you recon

I have got about 50cm of 2" lots of 1/2" and 3/4"
