Aluminum Tape Grounding System Success
Follow up to my earlier post.
I didnít have any PVC for the demo, but these photos should convey the necessary info. I left the roll of tape in the frame for scale.
You can see in the photos, the aluminum tape is mostly behind the PVC. I also included a photo of the final connection to the grounding wire. Very simple stuff here. But completely effective. A firm plastic squeegee or credit card does an excellent job of smoothing the tape out like glass, if you are concerned about appearances.
I hope this provides an alternative, low cost, simple method of grounding a PVC dust collection system.
If you are a careful observer, you will notice my system is the lightweight drain, vent, sewer PVC pipe that is two layer. I recommend avoiding this stuff if you have access to the thin wall, monolithic PVC. It was not available here. The stuff I used is slightly rippled internally probably creating unnecessary turbulence in the airflow and reducing overall efficiency. (Unless you want to get really scientific and start a discussion on laminar airflow and boundary level turbulence efficiency. See wing turbulators. Yes, I had a career in aviation).
