I get nightmares looking at all the rivets used to get ally floor secured to frames. It mystifies my mind how anyone can drill that many holes and quite in close proximity to each other on one side of a light 25x25x1.6mm tube. Also inviting rust as the rivets are on the bottom of frame.

Im actually busy now making plugs for floor molds thats gonna be made from GRP with CoreMat sandwich.
Made sample laminates with 4mm Coremate and decent CSM laminates - result immensely strong and the same weight as 2.5mm ally plate.

I am building floor trays that will tightly fit INTO the chassis frame from the top with 25mm flanges that rest on the frame tube. This will be bedded with SikaFlex 292 structural bonding compound between the flanges and top of frame tube. Only a rivet here and there to keep the tray in place until SikaFlex cures.
It goes without saying that the trays are only 25mm deep not to protrude below the chassis frame.

Ally and Rivet Has been done for many many years without problems in UK Kit cars..

Ally and Rivet + Glue has improved on this. The Glue ( Tigerseal of Sikaflex helps keep the opposing metals apart and well bonded.
