I read your reply as saying you experience the same thing... tho I described it in terms of the lower half of hammer travel, and you describe the lower half of key travel... also... my lower half of hammer travel should be the upper half of key travel.... described in terms of key travel I would have said that "at the begginning of the key stroke you need more DW then at the end" in taking these measurements... yes ?? That being said.... this balance rail pin problem you mention... would that be if the pin is angled back away from the key front a bit then ? grin... btw I thank you for the "he's nuts" compliment. I strive very hard at that you see... Cheers RicB -- Richard Brekne RPT, N.P.T.F. UiB, Bergen, Norway mailto:rbrekne@broadpark.no http://home.broadpark.no/~rbrekne/ricmain.html
