Having has a root around, I found the test Beetleweight robot made out of a shortbread tin that I had completely forgotten about. 5 minutes with a screwdriver later and now the arm works, albeit at half power but I'll take what I can get for the moment.



I noticed that the arm is sitting a bit squiffy in the slot, looks as if the arm isn't quite seated on the hub correctly so I'll rework that to make it flush and then add a pair of ramming spikes to the end of the arm to make it longer and a bit more useful at the moment.
