![]() ![]() Lastly you would need a way to lock the spindle in place so you can cut a pass without worrying if the spindle moved up or down at all. This can be solved with some drilled and tapped holes around the casting where the quill sits. A cheap drill press will not have any way of tuning the wiggle room out of where the quill sits. The quill is the tube with gear teeth on it that raises and lowers the spindle, it also holds the bearings for the spindle. The next problem to solve would be the slop in the quill. ![]() ![]() The more favorable option would be to buy an extra long ER collet holder and have the drive splines machined into it. If you can re-machine the spindle, you can put a 3/8" 24tpi fine thread on it where the taper used to be, as this is the usual thread that holds a hand drill's Chuck in place. A Jacobs taper barely holds the Chuck in place, and the only reason the Chuck doesn't just fall off is(under normal use of a drill press) you would only be putting force on it in the direction that keeps cramming the Chuck back onto the taper. The Jacobs taper on the spindle will also need to be replaced if not the entire spindle. You would have to replace them with angular contact bearings as these can handle both radial and axial loads. The only reason they are in that drill press is because they are cheap. These are meant to handle radial loads and not axial. The bearings in those cheap drill presses a standard ball bearings. If you wanted to bend the nail over after it's half way in, you would put a radial load on the nail. For example, if you wanted to pound a nail in with a hammer you would want to put an axial load on the nail when striking it with a hammer. An axial load is in line with the spindle, while a radial load is perpendicular to the spindle. This involves the bearings in the quill, and the taper that holds the Chuck on the spindle. I'll assume your talking about one of those super cheap drill presses that average around $70-90įirst is dealing with axial and radial loads. There are a couple of things you need to modify or replace to make this worth doing, and most of them require having access to a lathe and a proper mill.
