> I am just curious if there is any problems associated with 41mm >blow distance. Are the hammers hitting the strings squarely? Over/under striking?? You might need to shim the stack for this aspect or for the hammer bore = String Height minus Hammer Center Height rule (not really a rule but a good place to start). It sounds like low leverage to me.Where is the capstan on the wippen cushion (original wips?) Consider moving the capstan back, this will allow for a shallower dip and/or longer blow distance. You could also move the capstan back far enough to move the stack back to maintain wippen ratio but you'd have to relocate the keyframe forwards to maintain the strike Point. Look at how the shanks align over the wippen cushions to ascertain if moving the stack back will center the shanks over the wips better. How far do you want to get into this? -- Regards, Jon Page -------------- next part -------------- An HTML attachment was scrubbed...
