Default Tips for Installing a Dust Collection System


Quote:
There's no way around it: wood dust is a health hazard. Multiple health agencies have classified wood dust as a carcinogen. As a woodworker, whether professionally or as a hobbyist, safety should be the top priority -- even ahead of creating a quality product. This is where dust collection systems come in - the name is pretty straightforward for their purpose: they collect the dust that can harm your lungs and cause health problems later down the road.

Feel free to respond with effective methods that you have found for dust collection or anything you would do differently.

This is perfect timing as I recently added a sander and relocated my dust collector . I need to find out which way would be best to plump the machinery . I'm assuming 4" ABS and waste gates but I'll post a pic and see what the experts have to say

While the plastic duct system is more air tight (less leakage) it has the highest chances of sustaining static. Plastic dust must have a good grounding system attached to every foot of it. Inside the plastic ducting is the most efficient. I used metal ducting to eliminate the need for a ground wire along the entire length of the system. Beside the ground wire from the motor to the electric supply I have an external ground from the dust collector to the grounding rod that is used for the electric panel located outside the building. Being an ex USCG Damage Control (Fire Fighter) I cannot be safe enough from fire hazard, especially when we were out at sea.

JT; I'd be very surprised if putting the Copper ground wire on the outside of the PVC piping would be effective. My understanding was that it needed to be on the interior where of course it brings up other problems.

Static discharge from a dust collection system has always seemed to me to be a bunch of hooey!!! I've never noticed enough static in my system to even consider it being a potential problem. That is not to say it wasn't there, I just never noticed it.................until!!!! Recently hooked up a Dewalt 735 planer. (an outstanding piece of equipment by the way). While running the first few board thru the new planer, I would reach around to grab the board as it exited the machine. I'm telling you what.. from 6"s away, there was enough static to make the hair on my arms stand on end!!! I will now incorporate some sort of grounding medium into my system.

My DC system is 4" PVC no grounding and I have never noticed any static problems. As for the DW735 you shouldn't be having a problem there if the electrical supply to the planer is properly grounded because that grounds the metal body of the planer. I recently got a DW735 and again not noticed any problems.

I also question the idea of grounding the outside of a plastic pipe. The plastic piping systems I've seen advertised suggest running a wire down the inside and drilling a hole through near a connection so you can attach the inside to a bolt and another wire to the bolt on the outside. My preference was to use galvanized ducting instead. It's cheap and easier to ground. I still used the bolt idea but no wire needed on the inside. I also still used plastic ducting at the corners instead of galvanized bends. The plastic ones are much smoother. Use the aluminum foil duct tape at all joints and it works just as well.

Why take a chance? Very little effort and cost are required to avoid that potential problem. If static did cause a fire, the results would likely be catastrophic from your point of view.
