I don't see a metal spider, = so I'm thinking it might be that Knabe you mentioned. =20 =20 BTW, I am going to go look at a Bush & Lane Pompeiian in Michigan next = weekend. It is one of what B&L called their "traditional uprights," = which have the most massive plates of all the B&L's, is a full 58", with = the same speaking-length scale as my current one but longer backscale in = the bass and also longer backscale at the bottom of the long bridge, and = bass bridge direct to the board (not cantilevered). The Pompeiian is = also my favorite of the cabinet styles I've seen so far (same as I sent = you a picture of last year). This vintage (1919) should have the Wessel = Nickel and Gross action, and maybe I'll be lucky and it has lost-motion = compensation. However, while these models do have curved sounboard = rims, they do not have the plate-flange supported pin-block with the = upward-extended soundboard, but I'm not sure what extension in that = direction does anyway (my current one has the extension, and does have = an enchanting lower midrange, but who knows why?). Any exciting = developments after next weekend, I'll report further. =20 Regards, =20 Trent Lesher -----Original Message-----=20 From: Terry [mailto:terry@farrellpiano.com]=20 Sent: Thu 12/30/2004 6:53 PM=20 To: Pianotech=20 Cc:=20 Subject: Re: Recycled technology-cutoff bar =09 =09 Or if the original cut-off bar didn't cut enough off! - But I used new = wood, so you still win! ;-) =20 Terry Farrell =20 =20 ----- Original Message -----=20 From: Erwinspiano@aol.com=20 To: pianotech@ptg.org=20 Sent: Thursday, December 30, 2004 1:03 PM Subject: Recycled technology-cutoff bar =09 List I find this kind of thing fun when I can take a beautiful piece = of previously engineered something and adapt it to something else saving = big time & cash & utilizing something that originally was very expensive = to make & end up with a nice result A client brought in a 1900 ish Baldwin upright that ended up = needing more than it first appeared, including a board. It wasn't worth = doing so the decision was made to scrap it. The tech who brought in the = job wanted the beams & such for the maple & I'll be able to salvage the = spruce in the lam. beams also.=20 The real jewel though was that this piano had a laminated = soundboard liner just like Mason or Stwy grands & uprights ( not as = thick as a grand ). I managed to get it off in nearly one piece with = crow bars, chisels & an Oklahama speed wrench. Now coincidently I'm replacing the board in a 6 ft. 1 inch Mason = AA no. 28,246 which has ribs so long a cutoff bar was really a = necessity. =20 The old Upright board liner had plenty of stock for this & by = fashioning it to fit the corner of the AA I was able to install a = straight 28 inch cut off bar that reduced the overall length of 6 ribs = as much as 13.5 inches. My longest rib was 50" & one of the longest = I've ever witnessed in any piano. This rib is now about 37.5 inches = long. I don't believe its possible to use ribs this long and expect = crown support for very long. Although my observations of the AA's is = limited the 13 rib scale has shown the crown has not survived even with = tension resonator claims. Hence the few AA boards I've seen are usually = quite flat. The sound of this piano though fair was quite lack luster in = its tonal appeal if you know what I mean even though the board was not = seriously cracked up The Mason AA has a very wide body & hence very long ribs for a 6 = ft 1" piano The original rib scale was as follows on the left For clarity the measurements below are the actual rib speaking = length not including the piece in the notches. =20 1. 30 in inches 2. 37 3. 45 --------38 modified length 4. 50 --------37.5 5. 46 -------35.5 6. 40 --------32.5 =20 7. 34 --------29.5 8. 28 --------27 9. 28 10. 20 11.18 12. 15 13. 13 It's easy to see there is far more hopes for the longevity of rib & = crown stiffness than the previous scale. this mod also get the bridge = more nearly centered over the long ribs which is IMO a good thing.This = original bridge also has the transition bridge with all the usual funky = tri-chords. It's receiving a modified trans. bridge with bi-chord = replacements. I'll let you know how it turns out in a month or so. The action is = done & case stripped. The parts are in the finish process waiting for = the belly man to get it done so my finish guy(Roy) can have the case & = plate.
