Have cut out the front and back covers and started to get them into shape to fit them, there are two access hatches, one into the front of the hull the other into the back were the motors, batteries and speedcontroller will be

The whole front comes off so that there is easy access into the front of the hull, this is 1.6mm Mild steel

You can see the back panel that still needs to be bent, then the outside part will be welded in place and the hatch will be screwed

Have confirmed the sets i need for these parts to fit nicely, now i just have to do teh other side :)
