More progress on the heavy:

My feather is there next to it for a size comparison- it's scary how much bigger it is!

Cut out side armour from 4mm steel, was all cut out by me with a plasma cutter so all the lines are wonky and many of the panels were too small despite me having a guide but ah well! The panels are welded together at the back to increase strengh and have a crazy number of holes drilled ready for fixings (c.100).
Once I've decided where everything has to go I may weld some additional supports to the inside to further increase strengh as I am still concerned about that ali frame.
Also got some go-cart wheels and some taperlock bushes so just need to make a plate up to connect the taperlocks to the wheel hubs.
Any comments welcome!
