Hi All

I want to make a couple of seat boxes from Aluminium to replace the
existing pedestal seats. The idea is to house the batteries in one and
use the other for extra storage. I will then mount the seats onto one
end and hey presto "less wasted space". My problem is however how
thick is strong enough for the Aluminium plate. I was hoping to get
away with 5 mm plate? The boxes will be approximately 410 mm high x
360 mm wide x 650 mm long and have cuts outs on one side 400mm x 300
mm to allow access as required. What have you seen or built.

All feedback will be appreciated
Regards & thanks
Bruce
