[QUOTE="Dihusky, post: 484237, member: 10304"] Looks like a Hall Mark 3 or 4, built in the 70's I think, the Mark 2 had a collet quill and was 2 speed via pulley change, yours looks to have a side clamp quill. Good solid work-horse and accurate. Does yours have variable speed? If so it may be the Mk 4 as I don't think variable speed was on the Mk 3. For lubricants, we use Baby Oil, the Woolies stuff, only need a drop or two and then an occasional drop on tissue to clean swarf. Get some Eucalyptus Oil for cleaning laps, NOT the water soluble stuff, the good oil, cleans Laps beautifully, good prior to the Solvol treatment. Some of my AFG colleagues use Inox as a lube, haven't tried it myself, another uses Vaseline Intensive Care cream and mixes with the Diamond to make a paste before sucking into a syringe, tried it, but find Baby oil easy and effective. Remember.. when polishing less is more, don't load the lap as it will scratch, should be like there is almost nothing on the lap. [/QUOTE]
