Drill Press (Hydraulic)

thingiverse

This is a DIY drill press for attaching rotary tool flex shafts, designed specifically for drilling holes in printed circuit boards. I created this affordable and simple drill assist that requires minimal tools, nuts, bolts, and metal parts, making it highly precise. The detachable front mechanism holds the flex shaft in place, and I plan to modify it to accommodate a rotary tool. Some key points to consider: 1. To ensure a perfect fit in the base, print the two towers that hold the injectors vertically upside down instead of laying them flat on the printer's surface. Printing horizontally may require hot glue to secure them to the base. 2. I sourced the injectors and tubing from eBay, where there are numerous sellers available. 3. The critical connection between the injectors through the tubing relies on a simple hydraulic principle that requires no explanation. However, it's essential to synchronize the movement of both pairs of injectors. 4. The horizontal lift handles are attached using hot glue to the tops of two vertical injectors. 5. The control combiner, which holds the two horizontal injectors together while pushing or pulling, may also require some hot glue for stability. 6. Super Glue is used to secure part 1 and part 2 of the lift mechanism.
