When I used my drill press for a recent project, I found that the feed handles made my hands hurt. I decided to replace them with bigger knobs. I happened to have extra golf balls. These are old golf balls that I had lost in the backyard but found again recently when we were cleaning up after a tornado.
Drilling through golf balls was messy and created colorful swarf. Golf balls are slippery and round so it was important to clamp them well. First I drilled a small hole 1/4 inch from the bottom then a larger hole 1/2 inch from the bottom.

All I had to do was unscrew the old handles and screw on the golf balls. If I get tired of the golf ball handles, it will only take a moment to put the stock handles back on.
