Hi. I'm new to organs, but they've been an instrument I've liked for a while. I want to build my own one, just a small one to start off with and see how that goes. Upon searching, I found this website, which is sort of like an 'overview' as to how to build one. I want to build some pipes based on this:

http://www.sentex.net/~mwandel/organ/organ.html

I want to make about 20 pipes, that play the same notes as a bass guitar. (E1, A1, D2, G2) I haven't been able to find anything for calculating the lengths of the pipes, but in the link, they say they've varied the geometry as they scaled the pipes. Is there a way to work out lengths for the pipes and the geometry as you scale the pipes.

'Using this design, I built about 3 octaves worth of pipes. I varied the geometry as I scaled the pipes, so that long pipes were more slender with respect to their length than the short ones. This produced a louder sound in the higher octaves. I also found out that pipes that are long and slender are much easier to tune, and keep their pitch much better across a wider range of operating pressures and surrounding geometries.'

Is it possible?

Hi, bluiwolf welcome to the AOBG form.

On this page you will find a downloadable link for calculating pipes By BOB ESSEX but you will need Microsoft Office to run it, if you know your middle C pipe this will workout the rest for you.

Also you may find one of my videos on pipe building useful.

Even one I put together on voicing and tuning.

But if you need more help please let us know.

Thanks.
Just after posting I found this:

The Montre Pipes seem like a good thing to start with.
