Hi Sam,  I will tell you what little I know about voicing blowers.
This is how I did it on the Dutch organ.  I used a Player Piano Co.
blower without a reservoir.  It has a speed control for "kind of"
regulating the pressure.

I blocked off the wind input to my actual organ chest (on the
workbench), and fed the blower in through one of the drum ports to
pressurize the chest.  This was adequate for blowing one to three pipes
at a time for voicing and tuning.  I hooked up a pressure gauge to make
sure it didn't drop too much when blowing more than one pipe.

My organ is voiced at 7.5 inches of water, which I think is pretty
typical.  Wurlitzer used 8 inches.  I think the Windjammer blower with
45 inches would be way too high.  Of course, the flow rate will
determine how many pipes can be blown at once, but a single pipe
doesn't take much.

I worked my way through the ranks, adding one pipe at a time until I
was satisfied.  After installing the whole thing in the organ and
powering it up with the bellows I found that only minor tweaking to the
tuning was needed.

Here's a picture of the operation.  You can see the input hose in the
bottom corner, and I have about 2/3 of the pipes installed.
