I was thinking to buy another drill press but thought I'd try to make my own for fun. I didn't use any plans and kind of designed it as I went along. I built everything around the fact that the drill had threaded holes that a perpendicular handle can mount. A box was built around the drill and bolts mounted into these threaded holes.
After everything was finished, it works alright compared to a store bought. Regular drill press from store much more powerful, more rigid, and less noisy. A fun project nonetheless.
