Topic tags/keywords: drill press alignment special screw drill press quill

I’ve sent the following question to Delta, and I’m sure they will respond. I am also posting it here in the hope of a quicker response.

The Quill (part 78 on the Parts list) has a milled vertical groove which is kept in alignment by the milled end of a “Special screw” (part 81). The milled end of this screw is smaller than the main threaded part, basically round in shape, except that the sides are flattened to fit the width of the groove. These flat sides are what the sides of the quill groove slide against. Out of ignorance, I tried to remove a little play by attempting to tightening this screw. It would not tighten, but was easily removed after loosening a lock nut (apparently the screw was installed during assembly, and should not have been able to be removed, since the screw will not rotate within the groove). My assumption is that the screw was barely engaged in the groove. Unless there is some place along the quill that has been drilled or widened to allow the screw to inserted and/or adjusted, it appears a major dis-assembly will be necessary – something I’m not inclined to do. The only solution short of disassembly I can think of is to have the end of the special screw turned to a true round to fit the width of the groove. This would allow it to be inserted, but of course the ‘wearing’ surface would be reduced. If anyone knows of another solution to this problem, I would me most appreciative.
