While balancing keys on an SS-B I find that my target up/down weights can be had by either placing a small lead closer to the front rail or a larger lead closer to the balance rail. I know to stay clear of the mortises but other than that is there a prefered area of the key for leads? Another question is inertia - if I use the small lead near the front rail would this give more inertia than a large lead near the balance rail? It certainly did not feel different while experimenting. Is there an easy way to measure inertia in the keys? Thank you for your thoughts. Gene Nelson
