I did not. This article from FWW offers some information that you might find helpful.

If the link doesn’t work the article is from FWW issue number 153 from January 2002. The author rightly stats that NFPA regulations for grounding apply to dust collection systems 1500 cfm and higher, much higher than our typical 2 hp systems. We don’t ground or shop vacs which are dust collection systems of a much smaller scale. Some folks say they get shocks from their shop vacs but they aren’t of sufficient energy to cause combustion.

I used PVC on my system and I don’t get any static even during the dry winter.
