Since I am re-constructing a Caliola it would be nice to know the wind
pressure.  I figured that it is 8 inches as that seems pretty standard.
Can someone tell me if this is different?  I have the pumps.  Until
I get some of the case built I will not have them powered to measure
directly.

I use the word "re-construct" as I am missing the windchest, and
the pipework I have is fragments.  In other words, none of the pipes
have all four sides.  I just got all the measurements for the case and
am currently entering the data into a CADD program.  From this I will
be able to extrapolate the chest dimensions (see MMD 2000.10.02.01).
I have the stack so I have the on-center dimensions.

The tuning shades on the Caliola pipes are interesting: they are planks
of wood screwed onto the larger pipes and slotted.
