Could this be the problem part, the drive shaft glued to the panel behind?
I think the robot will have to be dismantled so that the shaft can isolated from the internal workings so it can be forced round with grips to break the bond with the panel, Not tried that sort of thing myself but I feel it might work. Of course a new gear will be required, perhaps there is a repro gear made.
Somebody got a bargain at $79
This has probably been mentioned before, the value and prices achieved for the Mechanized Robby Robot on a gradual spiral downwards as more and more of them are coming out of hiding, this only realised only $542 the seller being Zoomer7 a well known and respected toy dealer. OK it had one or two problems, needed a new drive belt and a flat spot wheel, but it is the knurled button knob battery door version and looks to be in pretty nice condition. Looks like somebody has got themselves a bargain, unfortunately not me, mostly due to the end time here in the UK (02:21 am) and me wrongly assuming it would go a lot higher.
Which wire diameter did you buy Ian, was it 0.63. 0.8 or 1.0 mm, I am thinking which would give the most lift off, that is after I have fitted the new repro rocket posts I have just ordered from Classic Tin Toy company, my Rocket man is receiving far too much attention, better be worth it, I am sure it will be, oh to see my Rocket Man launch a rocket and with its newly revolving antenna fixed at last.
Thanks for the heads up on the ebay listing David. It seems there are 3 UK members on the look out for Rocket Man springs, funkrobotic, chilli and myself, but I see the springs in this ebay listing quote shiiping to the UK at $61, perhaps a message to the seller to confirm shipping price is needed, seems way over the top for a small spring.
Hi Ranger, I regret not buying yours all those years ago when you offered it to me, I seem to recall you got it from Jay at Robot Island, then decided to move it on, just at the time I had bought an Astroman and had no Robot money to spare. This one came from Dan Morphy Auctions in the US, costly with import duty but worth it.
