I have a LOT of = various pipes of 20 inches and under in length to create mixtures and 4, 2 and 1 foot = ranks. If you cut the Dulciana down "6 pipes," then you needed six low pipes (8 = foot C thru F) to complete the rank. Can you say where these came from or was = the rank left without them?   Does anyone else have any comments about creating larger scales by cutting pipes down and adding basses. I'm facing that problem with my = organ, where the "diapason" has an 8 foot C of 3.8 inches in diameter, whereas my consultant says I should have 5 or 6" in diameter for a good real = diapason. I did manage to find a set of ten Haskelled Gemshorns" to add to the "diapason" = rank (actually an oboe in the bass and a viol d'orchestre" in the treble) at = the bottom. The Gemshorm basses have an 8 foot C of almost 5 inches in = diameter and I'm wondering if this is large enough or if I should try to use an octave = set of larger diapson pipes with an 8 foot C of about 6 inches. I have some = of these but they will need some straightening and soldering . . . I've not = got any chest ready so that I can hear any of these pipes yet, so I'm just asking = for your speculations and your sage comments on the issues in rescaling . . .   TIA, Roy Kersey

I havent got this rank = playing yet but from blowing into the pipes, they really do sound = pretty close to the other pipes in my set!       Harry Chase     .. .. .. .. ----- Original Message -----=20 From: Jess4203@aol.com=20 To: DIYAPASON-L@pipechat.org=20 Sent: Wednesday, September 03, 2003 9:54 PM Subject: [Residence Organs] Re: Cutting Down Dulciana     Hi Ed and List,   I'm very interested in what can be done with various ranks and = parts of ranks by cutting them down and thus increasing the scale of the = rank, adding wood or haskelled basses, or even (could it be?) adding = tuning collars or lengthening pipes to create narrower scaled pipes.

Larger pipes get smaller/shorter, smaller get larger/longer, cutups get lower ..... "...and the rough places plain"   "Haskell" basses can be made by the same process; get some old pipes and use some for "innertubes" with 70% diameter of the outside tube.   Best wishes to you Ed   ----- Original Message ----- From: <Jess4203@aol.com> To: <DIYAPASON-L@pipechat.org> Sent: Thursday, September 04, 2003 12:54 AM Subject: [Residence Organs] Re: Cutting Down Dulciana     > Hi Ed and List, > > I'm very interested in what can be done with various ranks and = parts of > ranks by cutting them down and thus increasing the scale of the rank, adding > wood or haskelled basses, or even (could it be?) adding tuning collars = or > lengthening pipes to create narrower scaled pipes.
