The 2 people that said cylindrical grinder, you were correct, it is the overhead drive off a Jones and Shipman 520:

The grinder however I am unsure about!






I belive it to be a Crystal Lake-http://www.lathes.co.uk/crystallake/
The shape of the castings look very similar, bulbous shape to the wheelhead bearings etc. what do people think?
I acquired the grinder last September from the nephew of the previous owner, who didn't know anything about it, when I got it it looked like this:
It has been stripped down and looks to be have been undergoing an overhaul, surfaces have been scraped as well as the bearings. It has been largely repainted just the wheelhead and tailstock needs finishing. There is a box somewhere with all the ancillary items which a previous owner has lost, the nephew could not find anything that looked to relate to it so I am in the dark with what I am missing. I have worked out the cam operated locks for the workhead and tailstocks.
The drive I thought was going to have to be homemade as finding something would be like looking for rocking horse doo dah. That was until I stumbled across an ebay listing for the above overhead drive! Turned out to be a chap I had dealt with before just around the corner from me! What were the chances.
It appears to be all there, minus some bolts and springs, a quick tweak with the clutch adjustment and that seems to work, it needs a taking to bits and a good clean, working out all the belt runs etc. The pulleys being the same way might be intentional, needs investigating. The lathes site explains the drive a bit if people are interested
