Does anyone have instructions for a jones and shipman drill poit grinder .It has two wheels on is about an inch thick the other is about quarter inch thick.The drillpoint grinder has an attachment which swivels and holds the drill so that the point comes close to the bigger wheel I can't figure how to do the fine tuning.It looks like one of these swivelling attachments you buy for an ordinary two wheeled grinder and attaches close to it only more sophisticated.Any help would be apreciated thanks.It may also do end mills .Alistair
