In a quest for better ergonomics, YouTube videographer pocket83 designed a simple and creative mod for the handles on his drill press by hollowing out a few golf balls. He removes the original plastic nubs on the rotating handle, drills out the rubber cores of a few Wilsons, and replaces them with threaded nuts to create larger handles with a smoother rotation.

I can’t help but wonder if there are common concerns people have with big shop tools, the way 1990s Grand Cherokees seem to usually have transmission problems, A/C failure, and a creaky driver door hinge (ours was a ’97 and I still miss it).

Are there known issues with your favorite tools, and if so, do you have simple modifications you recommend to keep them running smoothly?
