Hi there Touchweight lovers ! Here's one you are gonna just love. This is one of two Jacob Knudsen grands ever built. A good seven and a half footer, with no sound. I mentioned a couple weeks back I'd gotten the action in on this. It was the one with the keys coupled by a hinged post to the whippen. Well, heres some touchweight specs on it after I took care of some basic friction issues. I'll just take key 20 (first tenor key) as its very representative. FW 6.4 grams KR 0.5 grams SW 9.8 grams WW 19.8 grams whippen ratio looks to be 95/68 = 1.4 ^^ but that doesnt take into account the hinged post. DW 72 grams UW 51 grams F 20.5 grams BW 61.5 grams SW Ratio 5.8 This instrument has monster assist springs with all kinds of tension on them, fairly light but huge sized hammers. The assist springs didnt seem to have all that much affect on the BW tho.. perhaps the link between the key and whippen causes that configuration some problems ??... DW 60 and UW 35 (rough) with springs on. Hammers are pretty soft so those are being replaced, and I am going to go with a 3/4 medium Strike Weight curve on this and match leads a bit lower then I usually do and back way off on the assist springs, tho I plan on keeping them in there. As it was, the thing played like a truck and had no power at all. Even through the soft hammers you could tell there wasnt much sound to pull out of this thing. All was origional stuff, about 50 years old. Cheers RicB -- Richard Brekne RPT, N.P.T.F. UiB, Bergen, Norway mailto:rbrekne@broadpark.no http://home.broadpark.no/~rbrekne/ricmain.html
