Regards, Calin Tantareanu ----- Original Message -----=20 From: Erwinspiano@aol.com=20 To: pianotech@ptg.org=20 Sent: Monday, August 18, 2003 12:34 AM Subject: Laminated ribs Those of you who routinely use a laminated rib.=20 =20 My question is are these flat laminated pieces cut with a = crown in them or are you crowning the ribs in a curved caul. I know = this was discussed some time back but hey I don't recall it. If they're = laminated in a curve aren't they indeed more of a true arched rib (or = arched beam) than a solid piece of spruce rib stock with a machine cut = curve. In the rib glued in a curve the ribs the grain is indeed in an = arch even if it was made thick enough to cut the bottom of the rib flat = so as it had more material in the middle than on the ends. With a rib = laminated in an arch config. it's also possible to have a rib of uniform = dimension (if thats desireable). I don't know Phil F got me to thinking about that.
