I was supprised how easy it was to do the alloy including the anealing and bending. The worst job was drilling and countersinking all the holes. Boring!

Much easier the fibre glassing the outside and not as messy and smelly.
The solid rivets for the hatch wern't a problem, except for finding them. Most of the suppliers only sold a minimum of 1000 so I couldn't get countersunk ones and had to use truss head. They look good though.
The next job is getting the thing on the trailer and adding all the hinges and locks etc.
