Cheers Mel.

It definitely needs something! I'll consider box section like yours, but will probably go for thick, glassed-in marine ply to add weight to the doors for that all-important 'clunk'!

Thanks.

good luck.........hope it dont warp your doors.....

Ha ha. Good point.

It hopefully shouldn't tho', as marine ply is pretty stable - I don't think a piece that size will want to go anywhere.

I suppose heat, from hot days, could possibly have an effect? Hmmm. I think it should be ok; 'think I'll chance it...!

Thanks.

the door can warp not the ply. Ply is flat, door isnt.
Good luck

Ah!

Yes, I have just realsied that the door has a pronounced curve to follow the car's body. Hmmm, back to the drawing board...

Once glassed in, the whole structure should be pretty solid and stable (many kit car manufacturers actually glass-in a ply panel into their bodytub's floors - or am I thinking of bathtubs here...)

What I can do is to use two sheets of thinner ply, and laminate them together in the curved shape - they should stay like this when glue has dried.

What have other builders done here? Is the steel frame a 'standard' solution?

Cheers.
