Introduction: Golfball Keychain
When you live close to a nine hole golfcourse it is likely you find some balls. A friend came up to me and gave me about 80 used golfballs and I had to figure out what to do with them.
At the same time we were replacing gastubes on our gas-stoves we use to go camp with. About 40 tubes had to be replaced with new ones because they were "old" and we dont want to get into a insurance risk by not replacing the good ones with good ones.
When the golfballs and the tubes came together I came up with a simple idea of making keychains that are difficult to lose and easy to feel if they are in the pocket of your coat.
Have a look and have fun making one!
Step 1: This Is What You Need.
a vernier caliper
a 15 mm and a 4 mm drill
a break off knife
tube (15 mm)
a pedestal drill or handdrill
Step 2: Measure Drill Cut
You have to measure the thickness of your piece of tube. This tube was a little larger then 15mm. Then place your golfball in the machine-vise and drill a hole about halfway in the golfball (don't do it without your safetyglasses). Then with your knife cut of the edge an make it smooth. Fit in the tube and make a small incision about 1.5 cm away from the ball.Take the tube out and place it in the vise. Then safely cut it with the knife.
Step 3: Glue, Drill and Ring
Thoroughly mix your epoxy glue and place the cut of piece of tube in the ball. After 10 minutes of curing you can drill your 4mm hole in the tube. Then get your key ring and put it through both holes in the tube and there you have your simple and cheap keychain.
We have a be nice policy.
