With a space frame like the GT40 replicas the floor is an important structural part so no pissing about with this.

Started with a massive sheet of 2.5mm aluminium. Laid it on the bottom of the chassis and drew round all of the chassis members. Then out again and cut it to shape.

Then mark up and drill ~450 2mm holes. The eagle eyed reader may spot my school boy error at this point.

Then clamped back to the bottom of the car and drilled with 4mm into the chassis

Then drilled out to 4.8mm before being removed and stored for a year….

Then protective film off, admire the shiny!

Then absolutely crippled myself attempting to apply Sikaflex 252 using a hand held caulk gun. In hindsight I should have bought an air gun but I just hadn’t realised how hard it would be!

Stuck the floor on and then riveted it in place. ~450 rivets later and it was done.
