Hi guys,
A 10'6" bogie, if it materialised, would be after the 8'6" version; which still only exists in my computer as I'm still wrestling with how to make it truly 'universal'. If you want something that isn't currently 'vapourware', you might look at the PRMRP bogie kits. I hasten to add that I haven't actually got hold of one to try fitting my drive yet, but a quick trial against my Dad's models of 10000/10001 made it look highly likely it'll fit.
I'm not at all sure where I'd take a range of drive bogies to, mainly because different people want different things of them (rigid, compensated, sprung, 'proper' sprung, ease of assembly, split axles, I'm even looking at CSBs, etc) the options are almost endless. On that basis the simplicity of the PRMRP approach appeals as it can then be built up as people wish.
Rob,
I think you were looking at doing a DMU as well weren't you? I've got an idea or three, if the motor can go in the underframe. Who's bogies would you be using for the cosmetic parts?
Phill,
Roughly £40, depending on options (primarily whether you or I supply the motor/driveshaft and axles). Feel free to PM me with the sort of thing you're thinking of and I'll do what I can to help.
