A couple of tire pressure gauge questions:
I got tired of cheap Horrible Freight tire inflators, so I sprung for a bra=
ce of Milton S-506 inflators, thinking of they were good enough for the gas=
station of my youth, they ought to be ok now.=C2=A0 One in the garage, one=
in the shop...they don't see a ton of use.=C2=A0 Last week, I was filling =
bicycle tires in the garage with the hotdog compressor, and couldn't get th=
e air up sufficiently in the tire.=C2=A0 Finally went to get another gauge.=
..my electronic gauge quit, and my 50 years old Bridgeport Brass gauge need=
s rebuilding, so I grabbed the.othwr Milton inflator.=C2=A0 Turns out, I ha=
d missed blowing up the bicycle tires only by a miracle of Chinese rubber.=
=C2=A0 One inflator reads 50 psi while the other one reads 90.
So, like when two inmates at the asylum both claim to be Napoleon, at least=
one of them is lying. And at least one will need repairing.
So, two questions:.=C2=A0
1.=C2=A0 Any suggestions for a good reliable electronic or analog pressure =
gauge to verify/calibrate the inflators?=C2=A0 (I also need one to put in m=
y daughter's car, so gloveboxability is a plus).
2.=C2=A0 Anyone ever repair a Milton (or Bridgeport) tire gauge?=C2=A0 Any =
suggestions?=C2=A0 The Milton's aren't very old, especially in terms of wha=
t we old guys expect from our expensive American made tools.
Bonus question:. How might one calibrate a pressure gauge against a primary=
source?=C2=A0 I'm thinking of a water column or something, but 35 psi is a=
pproximately 80 feet of water.=C2=A0 I'm finding that impractical for home =
use._______________________________________________
