Is there any advantage = to having the friction of the flange change with the weight of the = hammer? Maybe in the bass it should be a little tighter, more stress. >> If you gauge friction by the number of swings of the hammer, then the = lower/larger hammers would automatically end up with tighter pinning. = Since this is the traditional approach to hammer flange friction (which = apparently has worked well), my guess would be that flange friction = *should* be graduated from bottom to top, as you suggest. Using a = spring gauge, you would probably need to graduate between the two ends = of the keyboard, so that the top has approximately half the friction of = the bottom. (Correct???)
