(back) Subject: Copper Pipes From: "Pieter Smit" <pieter@cadence-engineering.co.za> Date: Tue, 20 Mar 2001 08:16:48 +0200   Hi,   I have suggestions for forming copper pipes (I have made a few myself):   1. First heat the copper with flame to make it soft. Cool rapidly in water. While forming, it may work harden and may need to be re-heated = to soften again.   2. Make a few wooden mandrells (usually broom-sticks and bought wooden dowels can be used). Wrap the wood with many layers of paper (newspapers work well) to come up to the desired diameter.   3. Form the copper sheet around the paper wrapped wooden mandrells, = using two pieces of wood, one to hold the sheet against the mandrell and = another to form the still straight part of the sheet.   4. Soldering copper pipes is a lot more difficult that soldering = tin-lead pipes. The copper conducts heat very well and while soldering on one = end, the other end may become loose. It is especially difficult when putting the pipe foot, pipe and languid together. Things have to be kept mechanically in place, since solder will not hold them while melted. The pipe can be pre-heated with a flame and a soldering iron is then only used to do the final soldering. As an alternative, you can consider brazing = or silver soldering the pipe body and pipe foot, since this melts at a higer temperature. A lower temperature solder is the used to assempble the foot, languid and pipe.   5. Good luck!   6. Why not cast your own tin/lead sheets?   Pieter Smit pieter@cadence-engineering.co.za

These of course, are flaired to a bell like the trumpet instrument itself. Band organs had hooded copper trumpets and trombones.   Rick

He cut the resonators into sections, rounded out each section, and resoldered them. The only way you could tell any work at all was done and that they weren't factory-new was the seams every 2 feet or so. Need I say that Mr. Hershmann was an expert, and had been doing work like that for many years? ;-)     Regards, Bob, in beautiful Lake County, California, USA NAWCC 140818 http://www.jps.net/rrloesch alternate mailto:cuckoobob@eudoramail.com

The 'late' Werner Bosch organ in the 'late' St. Paulus Lutheran church (both destroyed by fire, 1993), San Francisco, CA, USA had a set of copper facade pipes which had a tone I always considered too 'hard', and didn't blend well with the rest. This, of course, could have been the product of the voicer, not the pipe material, but as it's the only copper pipes I've ever known 'up close and personal', it's all I have to go on. FWIW,   Bob

It's just not worth the trouble. If you do a little research (starting with this mailing list), there are lots of used ranks for sale at a variety of prices, typically a few hundred bucks for reasonable quality flue ranks. Reeds are more expensive, of course, as are the larger pitches. Sometimes you can get ranks for free (plus transportation) if you're in the right place at the right time, even 16' open woods!   On the other hand, if your goal is to have fun making your own pipes, that's another story. Why copper? Pipe metal will be a whole lot easier to both form and solder.   I'm sure others on this list will be more helpful, but I thought I'd put my 2 cents in.   -- Ed   #=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D#=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D#=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D# | Ed Stauff, principal software eng. | I don't speak | "Specialization | | Avid Technology, Tewksbury MA, USA | for Avid, nor | is for insects." | | "ed_stauff#@#avid.com" (remove #'s) | vice versa. | -- Lazarus Long | #=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D#=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D#=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D#
