Of course = yours is a bit older than the ones I have worked on but I think they are all = built that way. I was thinking more about centering the capstan but the magic line wouldn't be a bad thing to check. Since you are using a glue-on = heel on the wippen, you can experiment with the magic line and choose the one that fits the best. =20 =20 David Love davidlovepianos@comcast.net=20 -----Original Message----- From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] On = Behalf Of Farrell Sent: Tuesday, August 09, 2005 6:04 PM To: Pianotech Subject: Re: Knabe Action Parts =20 You may be right with the action spread. As I measured it, it was = actually about 112-3/4mm. It doesn't look like the wip rail is adjustable, but = maybe. I'll have to look closer. But even if it is not, it can be made = adjustable. And the move would improve the capstan/heel/magic line relationship - is that what you mean by "align the capstan better"? And yeah, you can move = the letoff rail anywhere you want. =20 Terry Farrell =20 =20 I think the correct spread is 113 mm. On many of those Knabes the = wippen rail is adjustable so you can move it in a bit which should not only = give you clearance for the jack but align the capstan better. BTW Tokiwa = also makes a wippen that works on that piano, though I prefer the Renner. = The let off button rail is also adjustable in and out to better align with = the jack tender. =20 =20 David Love davidlovepianos@comcast.net=20 -----Original Message----- From: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] On = Behalf Of Farrell Sent: Tuesday, August 09, 2005 4:22 PM To: pianotech@ptg.org Subject: Knabe Action Parts =20 I starting to dig into an action from an 1890s 6' 4" Knabe. Trying to = choose replacement parts. Original geometry is okay - could use a few tweaks. = It seems Renner does not carry an exact match for the original wippen. = Their universal wip seems to work best. However, the flange is shorter and = causes the action spread to increase from the original 112.5 to 115.5. However, = I think I can just slide the wip rail back a few millimeters to correct = that. =20 Below is a picture of the original at letoff. You can see that the jack = has lots of clearance between the knuckle and the felt at the back of the = jack slot. =20 Below is a picture of the action with new parts. Here you can see that = the jack is touching the back felt and at the same time it is still touching = the knuckle. But if the whole wip moves back a few millimeters, seems to me = all will be fine. I would use a different wip heel to line up better with = the capstan - it seems this would work fine. The new parts seem to regulate = out just fine. =20 =20 Or is anyone aware of better matching replacement parts?
