Seek Vacuum Gauge for Player Calliope
By Richard Price

I am new at mechanical music instrument restoration.  I am restoring
a calliope and I need to check the pneumatic pressures (vacuum).

The calliope has a positive pressure indicator on the air supply to
the whistles -- it indicates 0 to 30 ounces per square inch (0 to 35
inches of water column).  This gauge is from Fisher Controls.

I have looked all over the web but can find nothing like I need.  Does
anyone out there know a source of such a vacuum gauge?  Many thanks.

 [ The airmotor of the 1920s Tangley calliope can demand more than
 [ 20 inches water gauge of vacuum when it rewinds the 10-tune music
 [ roll, so I recommend a gauge that goes to 30 inches vacuum.  See
 [ http://www.nciweb.net/capsuhel.htm  (brass case optional) and
 [ http://www.nciweb.net/magnehel.htm  -- Robbie

 [ Magnahelic guages show up frequently on eBay.  Be sure to check
 [ the pressure range of the guage before bidding.  Some of them are
 [ much to sensitive for this application!  -- Jody
