Update 5 - Pre Grantham
After a few months of doodling and silly ideas, I began work on version 1.1. The plan was to get her ready for RL Grantham, and just in the nick of time, here she is.

Most of the hardware has been reused from version 1, because I'm cheap and it worked fairly well. The most obvious change is the removal of the (pretty ineffective) front hinge flipper, and replaced with twin lifting forks.

Each fork is made up of three 4mm hardox, plasma cut pieces, which are bolted together. The outer two are small, reversible pieces that protect the larger central one; which itself is part of the lifting arm. The forks are then joined together by two aluminium covers. This should mean that if one fork takes a horizontal hit, the other can help share the load.
My company recently bought a laser marking machine, so I thought it would be rude not to decorate the lower of these aluminium covers.

A quick test using gym weights suggests that the assembly can lift 16kg, easily covering the FW class limit.
I've even found time to give her a coat of paint, but it seems I'm better at engineering these things than decorating them.
Hopefully this weekend will be more successful than last time.
