Re: Polyurethaning the Seconday Problems

     I found that if I just left the secondary rotating for about 15 
     minutes while the urethane dried some, i didn't have too many dust 
     issues, and no drips either.  My secondary has a few dust bumps here 
     and there, but nothing major.  The sparks help distract people:)
     Keep an eye on the drill, gets hot when you run it for 20 minutes 
     straight, even at low voltage.

I'm in the process of building my first 6" secondary out of pvc.  I made a 
nice winding jig using a 1/2" drill / variace.  I can even use to spin the 
pipe while sanding.  Now that I have a nice clean & smooth secondary I began 
to coat it with polyeurathane while rotating it slowly.  The problem I'm 
having is that the PVC/Poly is picking up a static charge and attracting all 
kinds of dust and other air born junk.  I would like to make it a 
contaimination free as possible. Does anyone have any suggestions to keep the 
PVC free of static charge?  Maybee I can make a big Van De Graff with it ;-).
