(back) Subject: Making reeds From: "homer valenzona" <dochome@hotmail.com> Date: Tue, 23 Jan 2001 17:34:03   Dear List, I am interested in learning how to make reed pipes. I would like to make = the old type wooden regals and ranketts since they are difficult to find in = the "used parts" market. Audsleys' section on reed scales and voicing as well = as a Diapason article on short resonator reeds sound helpful and informative. =   I'd like to know more before I plunge myself into what seems like a complicated and not so well-defined craft. Topfer's treatise sound mathematical and precise but I can only understand/translate parts of it. = Is there an English translation of this book? I am interested on a hands-on demonstration or a more practical"tutorial" and would like to purchase the =   AIO's video, i.e, Paul Fritts' Making Reeds (1923) and Flue and Reed = voicing by Pike, Dunaway and Broome(1950). I would like to hear from anyone who = has viewed these videos, if the content would be helpful for me. Any other informative sources on reed making would be appreciated. Thanks.

One possible source for =   information is the book "Heimorgelbau" by Karl Bormann, published around 1972. It is in German, however. It is not longer in print but you might be able to find a copy at a well-stocked library. The Cornell University Music Library has a copy, for example. If you can find the 2nd edition, then you'll have the benefit of some corrections.   Herr Bormann describes how to build everything except the electric motor = on the blower. He has a section on reed pipes and he concentrates on baroque-style pipework. He shows how to build a small 16' Regal, an 8' Posaune, and perhaps a few other types. He does *not* included detailed tables of dimensions but instead gives general guidlines. He did build such pipework himself for his own instrument.   As no doubt others will indicate, however, reed pipes are not easy to = build or easy to voice. The tongue material is not easy to find, although you could probably purchase some from organ supply houses. You might be able to find a damaged set of Oboe or Vox or Clarinet pipes (low pressure) = whose tongues could be salvaged and then reworked.   Larry Chace

Farey-Jones" <avhfj@direcpc.com> Date: Tue, 23 Jan 2001 14:41:13 -0500   Thanx, but what I meant to ask was: In what way does a baroque- or classical-voiced pipe, rank or organ differ from a romantically-voiced = one. Are the harmonics different? Are the types of ranks in the organ = different? Are the pipe sizes different? etc?   Alwyn Jones Long Island, NY   ----- Original Message ----- From: "Bart Kleineweber" <prinzipal8@hotmail.com> To: <DIYAPASON-L@pipechat.org> Sent: Tuesday, January 23, 2001 1:51 PM Subject: [Residence Organs] pipe scales,ep chest rebuilding     > Dear Alwyn Jones and List: > > Alwyn Jones wrote: > > >Please excuse my ignorance, but what, exactly, is "classical or baroque > >voicing"? > > I was referring to periods of music literature.
