The original "Cam Doctor" was produced by
Quadrant Scientific
in Louisville, CO by a collaboration of Al Thomas, Cindy Anderson, and more famously William "Oz" Anderson. This company is no longer in business.
The basic tool was a measuring stand which centered the camshaft on movable V-Blocks, an electronic linear displacement gage, and a rotation encoder. The cam is rotated by hand and simultanous lobe travel and rotation are captured by an interface card and software and saved to a computer hard drive for analysis. The results can be compared lobe to lobe for an evaluation of machining quality, and to validate if the camshaft was manufacturered as expected. There are several more modern alternative products available now, from
Audie Technology
,
Andrews Products
, and
Performance Trends
for instance, but the original Cam Doctor is still a useful measurement tool if you are lucky enought to have one.
