"It works, but the problem is getting the right vertical height to place the scale so it is the same height as a record. I have to place the scale on a block off to the side of the platter, and then place the sytlus on the edge of the scale"
I can take my platter off the spindel. Then I place the scale on a small pad of paper with enough sheets taken off the pad so that the pad plus scale is the same height as the platter plus record. I measure dead-on with where the stylus would be on a record.
Takes about a minute more than the dedicated digital scales and you save at least $100!
