Clearly I'm confusing your term "underlever" with the whippen. What exactly are you referring to by the term "underlever". Thanks for your patience and remember I've been dealing with European terminology for about 30 years now. RicB Sorry I don't quite get it ... but 1 1/2 inch from where ? From exactly what point on the whippen to exactly what point elsewhere does this 1 1/2 inch come from ? From the key bed. Generally a S&S will have the key end lifter felt at rest at ~1 3/8" from the key bed and the underlever at rest is around 1 1/2" from the key bed which is lifted by the key to around 1 3/4" from the key bed.
