This might be an obvious question...
The other day whilst removing junk from the workshop, I opened the lhs gear cover on the Imperial Myford S7. There was a small plaque with 'Gear combinations for metric threads'
It seemed to imply that by changing one of the drive gears in the train the gear selectors on the gearbox would get metric threads. I seem to vaguely remember a 'metric gear cluster option' being talked about in a Myford catalogue some time back. Is this a 'standard' gear/set of gears that can be changed?
I'd appreciate any advice.
Many thanks
