Comments:
Although I prefer to do my own restorations for the fun, experience, and pride of it, I purchased this DP already restored from an OWWM colleague. I wanted a heavy duty machine with the 5" drilling depth, especially one of this design. I do want to improve the paint job on the table, base, and motor, but the machine is in great shape and is a tank.

Since all my equipment is used principally for woodworking, I've added a custom tilting table which, among other things, allows for compound angle drilling when the CI table is tilted as well. No drilling of the production table was done to attach the auxiliary table; it's held in place by two half-round pieces of wood that drop into the oil tray right and left and a single 3/8" machine bolt screwed upward through the bottom of the production table into a tee nut in the bottom of the auxiliary table. Removal or installation of the custom table takes about 20 seconds, and it's built to move rearward as the angle is increased in order to keep the bit roughly in the center. As you can see, the production table is in good shape, with only a couple non-through holes.

This unit has the huge single phase 1 hp RI motor which runs great. A PO had installed an old speed reducer in place of the motor pulley, but I've removed that and installed the correct step pulley. I replaced the big acorn nut on the quill lock bolt with a locking lever made from part of a 7/16"-14 machine bolt and a rod coupling. Works great; no more picking up a wrench to lock the quill.

The only suggestion I would've offered to Delta in the day pertains to the belt guard. Even when held in place by the three clips it makes an annoying tinny little rumble unless positioned just so. Heavier steel or some kind of sound-deadening liner would have helped. A small issue with a really great machine.
