We are assuming that all other = things are equal. Assuming they are, then the ratio in the bass end = will be lower and require more dip or blow than the treble. Assuming = you don't want to reset the capstan line, you can compensate for this = somewhat by increasing the spread between the wippen flange and the = hammer flange as you ascend through the action. The increased spread = will lower the action ratio. You might try a few samples in the treble = first. Shim out a couple of flanges by about a millimeter and regulate = a few sample notes and check for equivalency in the bass (you can also = recalculate the ratio itself on each end of the action and see if it = isn't more equal). It's not a perfect solution, but if you want the = regulation to be equal and you don't want to reset the capstan line, = this is an alternative to consider.

Dale My own personal feeling is that more keydip in the bass feels = natural and I often set actions up like this. Pianists who have given feedback = have seemed to like the actions, but I've never done a direct A-B comparison = between uniform keydip and keydip graduated from bottom to top to see if = they prefer the graduated keydip. Any thoughts about this? Any feedback from = pianists on this? Phil Ford ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
