Stepper motor or quadrature coil driven gauges actively drive the needle to=
 a given angle on the gauge, so they are not that sensitive to the needle w=
eight. However, our old-school tachometer only expects to drive against the=
 torsion spring in the needle movement, and its linearity across the scale =
depends on being properly counterbalanced. If you put on extra paint withou=
t adjusting the counterbalance then the tach will start to read low at idle=
 and high at the redline.

Subject: Re: [Tigers] guage needle paint

Think I told this story before.....a person I know worked in a factory run =
by BF Goodrich Aerospace many yrs. ago. She soldered and assembled parts to=
 gauges.  Her place in the assembly line was to solder a few parts, paint t=
he needle and assemble her section of the gauge.  I asked what the needle p=
aint was and she said she didn't know. It was just something in a little bo=
ttle and had a brush. She said the other people put one coat on the needle,=
 but she liked to put on 3 coats to make it look nice:-)
 Someone reminded me that these gauges were most probably calibrated after =
final assembly and testing. But it seems funny when we worry about putting =
too much paint on our needles.  These gauges, being used in the aerospace i=
ndustry, gauges that were assembled by workers who had to become certified =
solderers (never knew that designation existed) , each worker having a spec=
ific  task in the assembly and these gauges having to cost 10's of thousand=
s of $ each, just got a few dabs of some kind of red paint[http://cdn-cf.ao=

Aw shucks.  And here I was thinking that my car really came on the cam
after 4,000 rpm!
