Vacuum Level for Calliope Player
By Pete McFall 

Larry Claus asked about vacuum level for a calliope in yesterday's MMD.
When I built my stack for a playerless calliope, I took the vacuum off
the inlet of the pressure pump for the whistles and got the required
20" of vacuum that I needed.

What does Larry have as a wind source?
