I've suggested Giovanni start a new thread, but when he does I do have a query.
Did the very first Myford gearboxes use a different drive chain, and could his 12/30 gear actually be correct for his box?

Bill

Very definitely.

That link JohnF has referenced deals with this in detail, but Giovanni needs to know that there are TWO gearboxes around, not metric and imperial they are old Mark 1 and new(er) Mark 2, and the internals are different. That link explains everything.

To be strictly accurate there might be three versions of the Myford gearbox, depending on whether you are in the USA. Myford made a special version of the Mark 2 gearbox for the USA because their pipe thread standards are different from those in the UK and Europe.

As others have said this deserves a thread in its own right, though I been guilty of appending my three h'a'pence worth here.

Regards Simon
