Asking isn't the same as thinking, but it's a fair substitute and easier
for me, so: ********************************************

How abrasive is the dust from a woodturning shop at the dust removal
velocities encountered in a turning shop? Does it abrade PVC walls?


Between the fixed PVC and the moving dust are electrons stripped off
some or all of the dust particles or they stripped off the PVC? IOW, is
the charge (voltage) between dust and PVC tubing or between dust
particles?


Does living in areas of high humidity remove/lessen the possibility of
explosion from shop dust? Is there a correlation between relative
humidity and charging of dust moving in turning shop dust removal
situations'? Is the threshold RH known?


What is the ground wire inside the PVC pipe supposed to prevent; ie.
does the dust burn like gasoline vapor in a car's engine or does it
explode, whatever the difference is.


Would a humidifier reduce the risk of explosion in dry climes or would
it just make the turner uncomfortable and rust all his tools?


I know there are supposed to be no foolish questions, but asking without
thinking produced the above. Sorry.
