Out of the tablesaw – PZC Chatometry

A few Black Locust (Robinia Pseudoacacia) and Black Cherry (Prunus Serotina) samples were subjected to chatoyance measurement straight after being cut with a reasonably sharp tablesaw, and then again after standard sanding up to 1500-grit. The charts below compare the results showing that good or bad chatoyance and brightness may generally be spotted just after a tablesaw cut – at least with these species.

Brightness is not significantly altered by sanding:

GIFs below provide a visual representation of some cases:

Sample 1 out of the tablesaw – PZC = 10.0

Sample 1 sanded to 1500-grit – PZC = 7.5

Sample 2 out of the tablesaw – PZC = 17.1

Sample 2 sanded to 1500-grit – PZC = 18.9

Sample 3 out of the tablesaw – PZC = 21.7

Sample 3 sanded to 1500-grit – PZC = 17.6

Sample 6 out of the tablesaw – PZC = 10.8

Sample 6 sanded to 1500-grit – PZC = 10.1
