OK, I "fixed" my probelm. I know this is not the right way to do it and I'm sure someone will say that I messed something up but its rock solid consistent now with reading weights.
Whats I did was I noticed the "agate grooves" would pivot on the frame a bit, so I took a piece of paper and folded it once and then cut a tiny square out of it. I put the piece on one side of the "agate groove" piece so that it would fit snug in the frame so it would not move at all.
I know that this is not the way that the scale is designed to work but the scale works rock solid now
