There are several reasons why you might want to make your own jack. You might need a jack TODAY and can’t wait for it to come in the mail. You may need only one… the shipping would cost more than the jack itself! You might want a different or brighter color than is available in commercially-made jacks.
Here’s a suggestion. Go to your local craft store or woodworker’s supply store. Buy a wooden ball whose size is one-and-a-quarter (1.25) inches in diameter. (If you can find a ball labelled hardwood, that’s even better.) It will probably cost you less than a dollar.
Once you have your wooden ball, color it red with a permanent marker. Voilà! A jack!
You might think that your home-made jack is be OK for casual play, but not in an official competition. Quite the opposite! Your home-made jack isn’t a poor substitute for “the real thing”. The requirements for the jack are requirements for a wooden ball, and that is exactly what your home-made jack is. Your home-made jack will be just under 31mm in diameter: within the official size requirements of 30mm +/- 1mm. It will weigh around 13g: right in the middle of the required weight range of 10g to 18g. It meets all of the requirements for a competition jack.
After using a homemade jack for a while, I began wondering if it would be possible to get a shiny painted surface like the Obut jacks have. After a bit of experimentation, I made these. They are painted with three coats of “Sally Hansen Hard-as-Nails” fingernail polish ($3 per bottle). The first coat is white, the second coat is colored, and the third coat is clear.
Players in my club think that the easiest-to-see jack is Obut’s Fluorescent Yellow jack. But I have found that Testor Fluorescent Yellow Enamel Paint (which I found at my local Hobby Lobby) is even easier to see. My homemade jack (below) is on the left, and the Obut yellow jack is on the right.
After further experimentation, I’ve discovered a paint that makes a very visible color. It comes in a small spray can in Krylon’s “Short Cuts” line. It is a Krylon Hobby/Craft Paint called Glow Orange. I found it at my local Ace Hardware store, or you can order it on amazon.com.
A friend with back issues wanted a jack that he could pick up with his magnetic boule lifter. Here is my prototype, made from a battered old wooden jack. I simply installed six small screws (#4 x 3/8″). It works great.
