[QUOTE="Tony S, post: 487044, member: 20864"] The Ellison OCB is still in Leeds. The scales, I’m trying to get out of a total strip down. If the beam quartz crystal knife edge centre bearings are shot it’s going in the skip. At the moment I think they’re OK. The beam end bearings are OK. I tried two 1 troy ounce Canadian Maple coins, one in each pan, they didn’t balance. The Maples do have a tolerance so I need the laboratory test weights, I’ve never trusted the chain link adjuster from using them in the chemistry lab. Eventually I’ll get it to 0.001gm accuracy, 10 times better than my electronic scales. [/QUOTE]
