Aluminium or steel
What have you used and what are you thoughts.
Footwell to engine compartment on a Locost book chassis.
What gauge and grade material to use?

Mine was 16swg steel as it was what I had left over from the floor.
Alloy would be fine but I would want atleast 16swg.

I have used 16 gauge steel, leftover from floor as well. It porvides a lot of torsional stiffness to the chassis, and I want to use it for mouting
paddles and the master brake cylinder.

16swg steel
It needs to be strong especially if you are going to be using floor mounted pedals. It will probably need to be braced additionally as well if your
brake master cylinder is to be mounted on it.

Mine was aluminium, but it didn't bear any load.

guessing here but ...
melting point of aluminium 400 C ?
melting point of steel 1,600 C ?
ask yourself which would you select to protect your feet if there was a fire raging in the engine bay?

on my mk chassis, it was steel, not sure on the thickness through. as i have floor mounted pedals and it holds my master cylinder, i would go for
steel any way.

Hi
I think you would be unlikely to get petrol burning in free airflow to acheive the 600 degrees plus to melt aluminium alloy.
For me alloy is fine, braced with steel if required.
Oh! just out of interest ............. what is the melting point of fibre glass / CF

Melting point of polyester resin is pretty irrelevant as it burns like a candle unless you use special (more expensive) fire retardant resin.
You'll notice how much grp and aluminium has survived.
