Regarding static electricity and dust, it is a very real concern in industrial facilities. Examples include grain elevators and sugar mills, as well as production woodworking shops, cabinet makers, etc - all of which produce VAST amounts of very fine, highly flammable or explosive dust particles. Like you, I run one tool at a time. I also work with the main garage door and a side door open, and at least one, usually two, fans running, so there is plenty of ventilation - ie, there is never a high density buildup of fine dust in the air. Yes, you can get some static from pvc pipe, as well as metal pipe, but the risk of fire or explosion in my garage is very, very low. Yet to come, a filter box for the mini-split and an oversized air cleaner.

Riverton and Herriman are the best. I love living here. Are you an Oilers fan? I love all things hockey.

I’m in the camp of believing it’s just a rumor being passed around. I used to work in a grain elevator and dust explosions were always something we had in mind. They can be catastrophic but I’m not sure that there is actually a high enough concentration of dust in the system to actually cause an explosion.

The story on grounding comes from explosions in flower mills. The dust concentration in those instances was much higher than you will ever get in your dust system. according to stumpy nubs there are no documented cases of home dust collection systems causing fires from static electric discharges.

Coil a copper wire around a small section of pipe and ground it. You can rub in between the coils and generate enough static charge to pick up little pieces of paper right next to the wire. PVC is an insulator, it does give up its charge very easily even right next to a grounded source.

What causes the static that we're worried about? Is it dust and chips rubbing on the inside of the pipe? In which case the copper grounding wire needs to be inside the pipe as PVC pipe is an insulator and static generated inside will not "leak through" to the outside, and I don't know how to get it past blast gates anyway.

@@Loosehead to mount the copper wire you would drill a hole through the pipe so the thread is actually on the interior picking up the static.

The best reason to add a grounding wire is so it doesnt zap you when opening and closing blast gates. Outside of industrial levels of dust I doubt it would ever start on fire.

Yeah that is true. The shocking you does become annoying.

did you ever test the cfm loss from a short piece of 4" vs a long piece? I bet its the same. Talking about on a 6" system.

Video is informative and well presented. Just a couple of comments, constructive, of course. Had you used EMT to run the wiring using proper box offsets and connectors, your shop wiring would be more aesthetically pleasing and you wouldn't be having to dodge the MC while working on you dust system. The other is, by using 2 45's with a short piece od PVC between them, you could accomplish your 90 degree bends with less air flow restriction.

I have the same dust collector. I've been trying to figure out how to set it up I'm in the space of about a garage and half space with a wall between the garage space and half space. So thank you for sharing. I'm curious though why did you go with the 4 inch instead of the 6 inch?

@SaltCityWorkshop

Originally I was going to use the other side of the 4” splitter to go to a floor sweep, but I decided not to do that. Plus it’s easier to get 4” fittings, and they are easier to manipulate around corners and such.

The ground on pvc pipe is useless as pvc is an excellent insulator, so to discharge the static from it you would have to cover the entire pipe with a conductive material. Furthermore a small dust collector will not build enough charge to start a fire, the worst thing that can happen is you get a little zap. Great video.

Tip... after cutting the pipe, use a knife, file or better yet, a dedicated plumbers pipe deburring tool to knock back the rough inside edges. You don't want the edges catching anything and it also reduces turbulence. IMHO, I would only ground the outside of the pipe if you have a large static buildup that annoys you as you work in the shop. I agree with most others in that the chances you'd have any explosion are nearly zero and you'd have to ground the *inside* of the pipe, not the outside.

Hi, first let me say that I really liked your video. It gave me a lot to think about, it was pretty instructive. But I have a couple of questions. One is ask about the piping! PVC vs the flexible hoses. Now I know that the ridges of the flexhose affect the pressurized suction. But let's just say, I have a very small shop "a bedroom turned into a shop, small shop to be exact", and I have a fair amount of flexible hose, and I want to build my dust collection system. It Would be for about 6 tools, or 6 hoses, 4 tools, and 2 loose hoses for hand tools and clean up. So meaning 6 Blast-Gates. Now here's the first question. If I would cut the flexible hoses, so they would reach each separate connector, to each Y connector "precisely" fairly tight, no bending of the hoses. They would fit pretty much to the exact length. Could it do as good OR close to as good as the PVC "as a some-what substitute" OR even as tight as possible the ridges would still cause a certain amount of loss of suction? And 2nd. My Shop-Vac is a 2 1/2" hose 6.5HP. Now, Should I use 2 1/2" PVC piping all around? Or should I use a widener and use 4" pipping? Should I get better suction with the 4" or it would be the exact same with the 2 1/2"? Please give me your professional opinion! I have 1 shot, so I need to do this right. Thanks for your time and great video. Thumbs Up!

Hey Stephan, Thanks for watching, and thanks for the feedback! Before I answer your questions I want to say that I am in no way a professional, but I'll do the best I can to give you some guidance from the my experiences. 1. for a shop that small I would say it would be totally fine using flex hose instead of a PVC, given that you have a good dust collector on the other end. 2. with how I imagine you are setting it up, the blast gates and y connectors sound fine, just put the blast gate for the tool that requires the most suction closet to the dust collector. the further on down the line you get the more suction you lose. 3. I always recommend using as large of piping/flex hose as you can(4" or 6" is standard) . I just feel like the 2 1/2" gets clogged more when using a jointer or planer or tools that take larger bits of saw dust. BUT if your shop vac reduces it down 2 1/2 opening the air flow will be reduced to that diameter anyways, it doesn't matter if the rest of the system is 4", it will still bottle neck and the CFM's will be reduced before going into the shop vac. my recommendation is to see if there is a way use a 4" attachment with your shop vac instead of the 2 1/2". either that or get you a dust collector that uses a 4" opening even if the HP's are less. Like this Grizzly Hanging dust collector amzn.to/3FKVZYX. Check it out on amazon. I had this exact same unit for a while and it worked amazingly. Even though it is only 1HP, because of the diameter of the opening, it will allow the dust to go through the piping with little resistance. It doesn't matter of a shop vac is 6+HP, if the opening isn't big enough for the dust to flow through at a high rate, it's useless HP's. Well I hope this helps you! Again, this is all from my non-professional, personal experience. Let me know how it goes, and if I can be of any other help!

Im putting in my dust collection soon and I have one question, Were you concerned about your 90 degree corners? Its been said 2 45 degree connectors is much better for maintaining max air flow? Does this fall in the same category as grounding, which I do not believe in... Thanks...

Great question! I have not seen that my dust collector’s suction is reduced with the 90 degrees fittings. The fitting I purchased are 90 degree wide turn fitting from Home Depot. I would guess it depends on what HP your dust collector is, and how long your pipes are from the dust collector. For a 1.75 HP DC in a 2 car garage, The 90 degree fitting work great! Otherwise if you are concerned, yes I would use two 45’s to create a smoother corner fitting. Thanks for the comment!

@judefalconian6346

Y fittings are the best. Two 45’s are better than a 90’. It also depends on how much air your dust collector actually moves. Don’t believe what the box tells you. Ribbed flex hose is a killer when they are brand new. As time goes the dust builds along ridges and it becomes even worse. Flex hose is necessary. Just limit it as much as possible.

I have the same dust collector. Do you think it’s big enough to pipe a small shop? Or do you find that you’d prefer a bigger dust collector?

I would say it depends on how far away the tools are from the dust right. The further away they are the more reduction in suction you are going to get. if uou are in a small 2 car garage i would say you would be fine! That dust right is definitely powerful enough to use on each tool individually. Just add some blast gates to focus the dust on one tool at a time and it should work!

Check out Stumpy Nubs, he did a KZread video on grounding pvc pipe for a home dust collection system. Basically, it is impossible for the average home shop dust collector to pull in enough dust to cause an explosion. Wrapping the outside of the pvc will do nothing to prevent a so called dust explosion in the ducting as pvc is an insulator. The only thing that will be grounded is what is right next to the wire; the rest of the pvc can still potentially build a charge. Although you can get those irritating static shocks when touching the pvc and then grounded metal on you shop tools as the static charge will pass to your body depending on the relative humidity or lack there of in your shop.

Awesome info! Yeah I have gotten those pesky small shocks every once in a while ( you get them even when you touch the pvc while it’s on the racks at the hardware store) but I still feel like it’s an old wives’ tale that has been passed around. Still, you can’t be mad at anyone who takes the extra precaution to stay safe. That’s just not me. Thanks for the comment!

Hey I counted 2 90 degree fittings 😅

I used white gorilla duct tape just to make it look better

In the US in 2023 there were 1,600 fires due to lithium ion batteries in the US with 115 fatalities, could not find any fires related to home dust collection due to static discharge in any year. I am sure someone in the US is worried about static discharge with there PVC ducting all the while plugging in the EV car or ? into there home charging system.
