If I'm releathering the upper lip of a tibia:   1. What type of leather is best to use? On this one, I know that the = smooth side goes on the outside.   2. Are there different recommended thicknesses for the different pipe = sizes? I know that you could measure what's on there now, but if they've already been redone once, this assumes that the person before you knew what they were doing. Not always a good assumption.   3. I assume that hide glue is the adhesive of choice. But would fish glue = be a good alternative?   Thanks, John

The inside upper edge of the CCC is completely hanging off. Can't be doing the sound any good. = But I may be facing my own personal challenge on this matter in the near = future, and since I can't afford Clark, I thought I'd try for some free advice = from our resident pro's on the list, who are always so generous with the knowledge for which they would usually charge dearly (THANKS GUYS - YOU = KNOW WHO YOU ARE).   John   -----Original Message----- From: DIYAPASON-L@pipechat.org [mailto:DIYAPASON-L@pipechat.org]On Behalf Of KriderSM@aol.com Sent: Saturday, May 06, 2000 12:27 PM To: DIYAPASON-L@pipechat.org Subject: [Residence Organs] More leather       I would urge, especially in light of the fact that this is not the first releathering job on these pipes, that this process be left to the Clark Wilsons and Brant Duddys of the theatre organ world.   Musically, Stan Krider

I have worked on the San Francisco FOX which did have some of the leathered lips let go in the Main and Foundation because of = the moisture coming from the common chamber/outside wall to the restored Standford inaugural Wurlitzer and even on the NorCal Berkeley Community Theatre Wurlitzer. Trust me, with 45 years of working on pipe organs, a leathered lip is NOT rocket science. All you are doing is taking the = sharp edge off of the upper lip so that windsheet turbulance will not create increased modality resulting in harmonic generation. The thickness makes less of a difference to the sound than does just the simple process of = having a dull edge to interact with the windsheet. Cheaper pipe builders didn't even bother with the leather, they just flattened the edge of the upper = lip.   Best to the list,   Al Sefl A.
