You are correct about golf balls being used on C Clamps. At the Woodworking Shows, Oak-Park's American competitor uses them. I checked and they are not listed in the on-line catalog. I purchased from Oak-Park and I am very happy. Also, many golf balls have solid cores and many have liquid cores. Most of the newer brands are solid core. The older ones are wound around a liquid core. The package will tell you of the construction. You can also find product descriptions at www.golfballs.com You will need a very strong epoxy to bond to the steel threads of the clamp. -Derek
