Hi Bob, very sorry not to reply to your past messages as they went to spam. I was told by Westbourne Models that Graupner is for sale at 1 euro with debts of 9 million euro approx. I have been looking at the Technobots site and have today ordered their plastic chain and sprocket set and also some other gears to try out. The only problem is that the main shaft is 5mm and the bore of the gears is 4mm. So I may have to think of even changing the drive rod to 4mm. Or trying to bore out 4mm to 5mm.

Thanks Stuart

Hello Bob.

That's what I was hoping to do as the overall boss size measures 9.96mm.

Hi Tony,

I have just contacted -Gliders. He is going to e-mail Graupner for me to see if they are still available as he thinks that you had the last one off him. I will update you if I have any luck if not I am going to try a chain drive system as suggested by Bob Abell.

Many Thanks

Stuart
