>Hi Brett

>What Balance weight is is described in the first of the articles on 
>Stanwoods site.  Basically its (Downweight + Upweight ) / 2.

>Do you know how to take Downweight and Upweight measurements ?  If you 
>do then you should have no trouble going forward a bit on your own. If 
>you dont then I would suggest getting this down first before you start 
>putting clips on shanks. 

>Please download the following article courtesy of one of the finest 
>folks in our industry Steve Spurlock. There is a wealth of good piano 
>basics available from his site.
