I have just found this rare Haighton and Grindturn Lathe at my local scrap dealer and intend to restore it back to original detail. My version has the two vee belt pulley on the motor shaft but only one big pulley on the reduction part. My question is, why does the picture from the original advert show two belts as it wouldnt run like this – or am I missing something?

Limited adjustment range on motor for belt tension, two different length belts depending on speed range.

Fizzy,

is it a possibility that the manufacturer supplied the machine with a two speed drive from the motor requiring two belts when new and they were shipped like this. The owner would then remove one belt and keep to one side till a change of motor ratio was required.

Is there any means on the driven pulley to engage the pulley size needed for the job ? the remaining gear would just rotate on a bearing if the drive pin was removed.

I think that's an advertising photo – wow, look! 2 more belt ratios. It's not showing how the lathe was operated in practice. Easy enough to swap belts over when needed. The user photos on lathes.co.uk show only one belt in position.

Please replace that 'orrible orange monstrosity with a nice v-belt

Then write a few paragraphs about the lathe and send it to me with a few good pics for MEW
