I just purchased an old used drill press. The collars that hold the bed and drilling head to the upright shaft are of a type with which I am not familiar.
A hex bolt passes through the collars and is tightened to hold the collars in place. These bolts pass through cylindrical parts ground flat on the insides to connect with the upright. It is these cylindrical parts that contact the upright to grip it when the bolts are tightened.
In attempting to break the tool down into sections to carry it upstairs, I found that these cylindrical grippers were somewhat frozen to the upright. I had to knock them out with a woodblock and hammer—clearly not a useful method of loosening then to move the adjustment collars. These parts were well cleaned by the fellow who sold me the D.P. They are free of rust, pitting and other evidence of corrosion.
So my question is, what can I do to ensure that these collars do not freeze up again, and that I can keep them easy to adjust? Should I oil them, grease them, put on a coat of wax, what?
