1952 Jowett Javelin - 'DELIVERED'

perhaps bonding rubberized material to the chassis rails then adding the plywood (marine would be my choice) could work and not offend?

This has all the usual hallmarks of a Grumpynorthener resto.

And I continue to be amazed.

That list you started with.......?

JP - That is what I intended and have a roll of rubber in stock for this very purpose - the chassis rails will be treated with Dinitrol underbody wax prior to being overcovered with the new floor which will be plywood composite

Hmmm - List was quite small initially - now turned into a rolling restoration and there are not too many areas of the car that I will not have touched once it's finished - still that's life in the fast lane of vehicle restoration

The issue of mounting wooden flooring directly onto a metal chassis, even today, has issues. As already identified the first is the retention of water between the metal and the wood and finding a suitable method of both protecting both surfaces and the ingress of any water. Having recently completely refurbished a trailer, I used a product sold under the trade name of DENSO tape. This product, for those who aren't familiar is effectively hessian tape, which is heavily impregated with a form of grease. I was introduced to this tape whilst building a bungalow and various farm buildings, and when water mains were being installed. It is often used to wrap pipe junctions, etc... and can be undone years after having been installed, as it doesn't actually solidify. I spoke to the manufactures re my trailer issues and was advised to lay about three layers deep, on top of the trailer chassis, effectively as a sandwich. The floor was then placed on top of the tape and bolted down. Where the tape was punctured to allow the bolts to go through, it was effectiverly self sealing and retained its integrity.
I followed the example of Ifor Williams (trailer manufacturer's) and used a sheet of PHENOLIC PLY for the flooring. Again for those not familiar with this product it is sold in 10' X 5' sheets by specialists suppliers (Google Search advisable). This ply makes marine ply look like tissue paper and due to its construction is totally waterproof when manufactured. It can be cut with a saw, but the newly exposed raw edges have to be suitable treated to retain the waterproof properties.
My comments are not for one moment meant to treach you to suck eggs, merely proffering another alternative, etc...

I’ve got “Buffalo board” floating around my head - I assume that’s a trade name of the same stuff?

another one with a dust eater...bless 'em. mine makes her own bases , ingredients in general have come a long way in the last coupe of years , her gf chocolate brownie is as good as you will taste anywhere!

There’s a lot of it about! My eldest son and my daughter are both coeliac and the choice has improved massively in the last 5 years since they were diagnosed, but it can still be a bit hit and miss.
