i honestly appreciate your comments and thoughts. i have waited 12+yrs
for the legal nightmares to come to an end. now that they have and i
have the settlement money coming in. (so yes, perhaps to some people i
do have money to burn. depends on one perspective. ) anyone who would
happen to be in the shop have also been waiting many years to have the
opportunity to be working on projects instead of sitting in the arm
chair just waiting to die. now that i have the opportunity to build a
new shop and equip it i have a sense of urgency that people outside
looking in probably do not understand. i wish that were not the case. i
wish i was able to convey in words why certain things are important at
this point in time.

i would agree, that many small air compressors can to plumbed together
and their individual pressure switches be set for them to cut in and cut
out at specifed pressures. part of that is to keep the circuit breakers
from tripping on all the startup current is all the small air
compressors started up at the same time.

right now i am looking at the quincy duplex units. i am also looking at
the ingersoll-rand at northern tools.
