Ron, Funny you should mention this. I've got a customer with not enough job and a machine shop in his garage. He milled a small collection of round weights for me, from around 50g to one that's about 180. Almost the size of my scale calibration weight. I always appreciated the mass loading on the back of the Baldwin 6000 vertical, and after one of Del's classes I decided to be prepared. (the customer also liked feeling useful). I used one on a three-legged spinet, but haven't tried a true vertical spinet, yet. The Acrosonic sounds like a great candidate. Can't weight to try it! (sorry) What did you use to space your mass over the pins? Guy At 03:13 PM 3/4/2004 -0600, you wrote: >I got to be a junior grade hero the other day.
