Floor

[Jimmyd]

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?
