Spent the day working on the table of my of my old leland gifford drill press. Its roughly 14 x 14 square with a coolant trough around it. Table is on dovetails for up and down about 20" movement and by hand. The table alone weights around 70 lbs. I rough mounted the X Y table toady and it added another 70 lbs to the table. I made block to match the bases contour 4" wide and 5 1/2" long with a boss to set in the slot where the foot switch slot was. Fiddled around to get it level in both directions. On this I set a 1 1/2 ton long stroke jack. It has 20-40 range. It sets back within an inch or so of tables dovetail casting on the table. I can now jack up the table instead of muscling it. A couple lag screws to mount the jack and some small mods to release handle and handle and block and its going to be very handy. Each stroke of the jack raises the table around 1/2"
