A friend gave me a bag of billiard balls. I figured I’d make some coat racks out of them.

Holding them to drill holes to insert dowels can be a challenge. A quick check returned several good solutions. At first, I had elaborate designs in mind for the means of holding the balls, but items already setting on the drill press table presented a quicker solution.

A piece of plywood I use under material and for drilling test holes had a hole, which was a good size for holding a ball. Another piece of ply near it, for the next drill job needing a clean backer, was perfect for raising a clamp holding the ball.

A quick twist or two and I was ready to ruin billiard balls, and gain a coat rack.

I drilled a few for shift knobs and used a metal lathe. The headstock had a 3” hollow shaft so chucking up the balls and looking down inside the headstock allowed me to center up the numbers allowing me to drill at the exact opposite.

Have your say...
