measuring key weight ratio

[Richard Brekne]

Hi Julie

Pianotek sells a good scale for use with this work.  They used to sell 
Ohaus scales, and I had mine for several years before I managed to smash 
it. I have another on order. They are a bit pricey, but they are very 
accurate and stable.

I cross compared with a couple smaller pocket versions and found those 
to be not nearly as dependable as advertised. I'd get variances of up to 
0.3 grams weighing the same parts sometimes. Other times I'd notice 
whilst weighing Strikeweights that they were not sensitive enough to 
changes in effective shank length that occure when you put the shank on 
the weighing table  a mm or two off from center.

Cheers
