Bruce, I took a small 4x4 block and drilled one hole for the big end and another for the small. With a 1/8" bit positioned in either hole (smooth end out) the rod arm was level and I could weigh the big and small ends consistently. I marked squares in pencil around the scales and the block to make sure they didn't shift position and marked a landing zone on the scale for consistency. Rinsed and repeated until I could get the same readings.
This harebrained scheme was the third approach. The first two showed a lot of weight drift because there was too much surface area on the block side. In this case, smaller was better.
