RCH measurement

[Flivver250]

I recently moved things around on the Jeep and had to re-establish the pinion angle. Angle finders are useful tools backed up with a good set of eyes. The difference between a smooth ride and a four wheel vibrator can be a minute adjustment that comes down to tweaks in the RCH range. If you don't know what a RCH is, chances are you shouldn't be working on your Jeep.

I guess I shouldn’t be working on my Jeep.

Bawdy measurement slang used by mechanics in the 1970's.

Oh shit! Hahaha, now I feel stupid

Some of us still regularly use that very useful measurement.

Well it could be worse, at least it's not so fine as to have to measure with a BCH

My generation is not that precise, A CH is close enough for us

Your generation shaves. My generation was keenly aware of varying strand diameters.

I've submitted the entire series of CH measurements to the International Bureau of Weights and Measurements for official acceptance. Still waiting for their reply...

I’m pretty sure they stopped growing them, at least I haven’t seen one of any color in the last 3 decades.

Never was particular if it was R/B^3/G, usually CH was good enough.

The toughest part is finding a CH to use to measure with. They are harder to come by these days.
