Rubber ball drilling jig

As discussed in a recent thread, I needed to find a way to safely drill holes in rubber balls to put on the end of a child’s drumsticks. After receiving lots of suggestions from my fellow Jocks, I ended up a) freezing the balls and b) making a rubber ball sandwich. The freezing (chest freezer for a few days) didn’t actually get them very cold/solid particularly, but it kept the outside of the ball from getting damaged by being held in the jig. There was no difference in drilling the frozen vs unfrozen ball.

Here’s the jig – two scrap pieces from a bed project a couple years back, two leftover bolts from a swing set, and a bunch of drilled holes. I didn’t even need the wingnuts I found to put on the end of the bolts – they aligned everything without needing to be fixed in place and it made disassembly easier too. The larger holes were drilled with a forstner bit. I recommend slightly rounding the edges of the holes that hold the ball, as they damaged the unfrozen ball slightly.

Final steps were to superglue the dowel end into the hole and apply two coats of Plasti-Dip which was in stock at Harbor Freight.

One of the bolts is slightly loose in the jig because I didn’t get the larger hole quite centered and had to do another one, so the press fit didn’t quite work out. If it bugs me I can always epoxy the bolt head into place.

I like the rubber ball idea! I had some 1” threaded polyethelene balls (salvaged from something I don’t recall) that I used but they were not robust enough for kids.

But, why not wood since you covered them with Plastidip?

Thanks for the comments all!

Oldnovice, to answer your question – the rubber ball bounces better, and when he is old enough to reliably not try to eat them I can skip the plastidip stage entirely and then he can have the patterns that show on the actual rubber balls. Some of them are pretty cool looking.

Have your say...
