Floor
 

Given that I just happen to have a sheet of 2mm mild steel I was going to use it for my floor. Given the thickness and the fact it'll be fully welded would it be sensible to bolt seats to it? Using good sized washers or small plates to spread the load.

HI Jimmy
That’s how I did my car. I stitched wielded round the floor to stop it from distorting. Bolted the seat to that with large washers. No problem with SVA.

Thanks Frankie. Just what I wanted to hear!!!

Been wondering about this aswell. If you use ali for the floor, is it OK to just bolt seats to the ali if you use big washers? Seems to me that in the event of an accident, they would just tear?

What does everyone think?

My advice would be that if you're going to use ali I would weld in some 40 x 3mm steel trip to take the seat mountings, from the outside of the chassis to the transmission tunnel. There have been SVA failures when the tester believes that aluminium isn't sufficiently strong.

If you're using ali, bond the floor in place with polyurethane adhesive/sealant (Sikaflex or similar) as well as riveting, it all helps the chassis strength.

I have ali riveted and bonded floor and will be using the technique chris describes.

However do the bolt heads protude under the car? or is there a nother way?

A little heavier,What about 2 strips of 25x25 or 25x50 across between the chassis rails and bolt to that, surely they could not knock that back and it would be very strong.
Gives rigidity and a bit more side impact protection.

Thoughts on this one....


Cheers all

thats what i intend doing next week when my subframes arrive for the bucket seats. 2 x 25x50mm rails between the outer chassis rail and the prop tunnel...all ali floor to save weight bonded and rivited

If I was building again, it'd be an ally floor for me.

The gap between chassis and steel floor is a lovely rust trap >:( even powdercoated. I reckon powdercoating the chassis, then fitting an ally floor would stop any rust.

On my car, rust has got hold right at the back of the floor, just in front of the axle. Rust is pushing the floor away from the chassis in between "stitched) welds. With it being welded it's not an easy job to remove, clean up and replace either ;(

visitors to the 3ge stand at Exeter show might have also have spotted that they had put in some extra box sections for seat mounting :D
as for sealing the floor schultz is really good and what do people think of putting in a couple of strategicly placed drainholes
