Worked like a charm
Bought a 12" dobsonian telescope from a seller on eBay. It came with lots of accessories, as well as three counterweights. The accessories and my 2# eyepiece was too much to balance. This counterweight ring was just enough to put the telescope back into balance.
Farpoint FP315 Astro counter ring weight for meade lightBridge. These weights are sold individually and weigh 1.875 pounds each. In tests with a 12" telescope the basic set, plus 1 additional weight nicely balanced a 2" eyepiece, a Telrad and a Stellar View finder scope.
