----- not at all, as long as you live high up!!  Wrap cord (wire, kevlar) 
around the spring can, the number of turns corresponding to the number of 
turns (surprisingly few) that it would do for a complete record. Put a weight 
at the end of the cord corresponding at least to the pull the spring would 
have given when fully wound. The weight will sink, and that is why you need 
to live high up <extreme grin>. You then have a drive that is more even than 
the spring drive. If the cogwheel joined to the spring can is horizontal, you 
need a pulley to take your cord over. The only serious problem is that the 
bearings are not really made to take the sideways force, so lubricate well 
and use it infrequently.  

Kind regards,


George
