Drill Press

Make a useful drill press from commonly available parts. Total cash outlay: around $20. This tool has height and speed adjustment built in. A full description of what goes where will be added over time.

--2025_October: Hi gang! Another update; this one is optional but it should reduce the wobble in the quill body. I rummaged thru the collection of springs from Harbor Freight and found a couple of compression springs that seem to do the trick. Print two each of the Spring Cap 02 and the M4_T_nut_03. I've updated the  DP_Quill_Body as well but the previous version will do. Now here's the trick: Slide the cap onto an M4 x 25mm SHCS, then put a compression spring into the cup. Slide an  M4 T-nut into the 2020 column slot, position the quill body so the hole in the back lines up with the hole in the T-nut. Push the bolt-cap-spring assembly into the T-nut and screw it to compress the spring. This can be repeated on the side if needed with a second bunch of parts.
