Hi, i am going to be cutting out a few spots of rust in the wagon where the fuel tank bolts in, and am trying to find out what thickness plate and where to get it from in the perth area.
i dont think a street sign will look right :)

thanks Dan

Hi Dan, use 1 mill cold rolled steel, easy to work with and thick enough for these old girls :D , Trev 8) .

I'm with Trev on this, Dan...
I have used it and it lends itself well to being ground back after welding.

I have been forced to use .6 mm with my little Jap car..... and it's a pain in the (you know) to weld using a MIG.

If you find yourself blowing through and can't get your settings any lower to weld with - try backing the joint with a brass or copper plate (scrap metal merchant)...

frats,
Rosco

careyman, I wold be careful using old panels for repairs, if the already have some corrosion the thickness can vary making it harder to weld.
I got a huge sheet of 1 mm steel for about $40, can't go wrong :wink: , Trev 8) .

I would rather use Zincanneal sheet, you can weld it pretty easy, stronger than mild steel panel in the same thickness, and doesn't rust........

I use 1.0mm zincanneal.

for the floor plan, you may need to put swage lines in it for strength?

i've alwalys patched floors with zincanneal, but if it's an entire section I will buy a repro for the matching lines.

Cheers

Cold rolled lends itself to being dollied up into curves or complex shapes a whole lot better than zincaneal.

Zinc aneal is a lot harder.

For floor sections,1mm will do the job fine,but Id personally be leaning towards 1.2mm,or even 1.6 for something like a

fabricated Trans tunnel (not that you will be doing this....but I'm on a roll....)

Thanks guys. I'll probably go the 1.6mm to patch a couple sections of the floor. They are fairly flat so it should be easy-ish.
