Get yourself a trend digital angle gauge available from machine mart worked a treat on my tubes I used 2mm x 25mm x 25mm box for my chassis just
remember the thicker the material the heavier and slower the final car will be

You can use what you want, some go thinner to 1.2mm (18swg) for lighter track cars.
I'd stick with 1.6mm or 1.5mm (16swg) for the main chassis and use 2mm on suspension components, but if you already have a pile of 2mm stuff use
it! It'll just weigh a few extra kilos!

Personally I didn't aim for the angles, I cut right angle to the maximum length and then trimmed when on the car.
As mentioned, going for the metal you have available is often better than trying to get the specific stuff, as different places stock different
thicknesses. I built up my main chassis with 1.6 as that is what Camp Steel sell, but the last few brackets and things are made of 2mm as I had bits
left over from another job. Just be careful when it comes to the difference between imperial and metric. 0.4mm doesn't sound much, but if the
metal doesn't butt against each other the weld will do a spectacular job of drawing the metal together.

Hi Ron,
Firstly Good luck.
I have built a couple of frames and I tend to use 2mm SHS, just because its easier to weld and not blow holes in.
what sort of spec/style are you thinking with your build... or not decided yet.
Regards jon

Hi Ron and welcome
I used 2mm because I could get it cheap from work and I was arc welding rather than MIG welding in those days.
I reckon the difference between using 1.6 and 2mm is about 12 kgs on the frame.

Assuming it's good steel, can't see why not. I'd be wary which orientation you use it as it'll throw other dimensions out
when adding upright pieces or horizontal pieces.

You can buy the pre cut chassis cheap enough these days and then you just weld them up.

Thanks
