Periodically, we get people in UK asking how to convert 60Hz Shugarts to
50Hz.
Doesn't anybody see the simpler solution?
Trade drives
Shiping 8" drives and ensuring they stay undamaged and aligned is not
trivial!
trade pulleys
Assuming you can find soemody who has a spare 50Hz pulley.
but is it really necessary to remachine the pulleys?
That, IMHO is the simplest solution. The machining is very basic. OK, not
everybody has machine tools, not everybody wants to learn to use them. In
whcih case, it may be possile to find a firendly local model engineer who
will skim a it off the pulley in exchange for you helping him. Perhaps
he needs his PC sorted out, or some simple electronics designed, or...
