Hi from Arizona Dave. I really appreciate your tip for handling the static. I've tried a number of things that made no difference. Having worked in a cabinet shop for 10 years I have a good supply of system screws & 5mm bits. I will be using this method as I set up my home shop. Thanks again!
While procrastinating, I puzzled over whether to wrap a wire around the outside of my dust pipes, or fling a wire down the inside. But now you have shown how to connect both the inside and outside! Yay!
Just wanted to thank you for you lightening rod idea. I installed a PVC based duct system with a Laguna PFlux 3 cyclone dust collector. I used your technique to mitigate static. Great idea - thanks!
@@DavidStanton the only way to physically remove the WHOLE amount of static is to cover every square inch of the pvc. You're talking absolute nonsense.
Well done! Thank you for the insights and direct presentation. I've subscribed partly because, unlike many Aussies who ham it up with their regionalisms, you are perfectly intelligible even to a Wyoming U.S. ear.
Great idea! Probably another benefit, since some Woodworker's have electronic equipment in shop, you want to avoid any static charges, as small components (computer chips) can be burned out with just one shock.
Thanks Dave. You do have a talent for thinking outside the box, or in this case, outside the pipe, if you excuse the pun. It makes perfect sense now you say it, I have seen the products that you wrap around the pipes but like you point out, they aren't earthing the inside of the pipe, which is where the combustible materials are.
Ahh. Perfect. Thanks. I think my static problem from the exact same setup took the throttle out on my last ts55. Plus, it's super disconcerting when your doing something carefully, but at the same time waiting to get zapped.
David, it's possible to get adhesive copper tape in various lengths and widths - stick that on the outside of the PVC pipe and put the screws thru' it. Maybe drill pilot holes first. Spiral or straight? Don't know ... just passing on the thought. Of course the ends would need joining up and earthing as you have done with the stranded copper wire in yr video.
Great video. I'll use your method on my next video about my micro dust collection. Always use braided wire for static collection. Braided wire has much more surface area to collect a static charge and is way better suited. Any bare uninsulated wire will work but braided works better. Great job David!
The Euro screws are a good idea Dave. Nothing inside to snag anything moving through the pipe. In the side is a good location also. Nice job all around. I will do the same to my system. Thanks Dave.
When I started getting nasty static shocks from the new drumsander LEV I realised that I needed to earth the pipe. I stripped a length of copper wire and stuffed it down the pipe, out through a small hole, and wired it straight into an ordinary mains socket earth pin. Its pretty scruffy but it does the job. The copper doesnt need to be in contact with the plastic pipe to make it work. PVC has no conductivity - if it did the static wouldn't build up anyway. It earths itself onto the copper across the air the same way that it affects the hair on your arm.
Dave, tell me about the hose of a construction vacuum cleaner, you can also use this system, it gives you an electric shock so that you are already afraid of the vacuum cleaner
@DavidStanton I have plastic hoses, the ones that were in the basic configuration, and therefore I receive a portion of the current discharge into my limbs, but this is not a reason for despondency, but on the contrary a great incentive to figure out how to get out of this situation with a more or less acceptable budget, and your ideas inspired me to fight static, thank you!
Biginuf m That's an idea, thanks for watching! I am curious as to why you feel a problem didn't exist? I stated in the video that there was a static buildup as the hair on my arms always stood up when I went near the pipes before I came up with this simple fix.
Очень полезная информация. Давно искал как избавиться от статического электричества в вытяжной установке в своей мастерской. Спасибо большое из России!
As always a well thought-out endeavor. Thanks I wonder if a rivet (with the wire tightly wrapped once around it as you “pop” it) would have worked as well.
I've hear that static fires aren't a problem in smaller shops like yours, it only a real problem in the extremely large industrial shops. The only thing you have to worry about is getting a little zap from you pvc pipes. On a side note, I recently bought some grounding wire to use on my small Shop Vac system. I also decided to upgrade my shop vac from a small Craftsman to a Ridgid which has almost 3 times more suction and about half the noise levels. Funny thing is that with the Ridgid vac, I get pretty much no static, where the Craftsman vac I could feel static from 2 or 3 feet away from my cyclone system.
Impossible to ground PVC. It is the insulation used on all wiring as it is one of the best insulators known. You may be discharging some of the nearby static, but the system is not grounded.
I appreciate the science behind your comment. All I can say is I never get a zap from my system since I did this work to it..before it was all the time.
Great stuff Dave. This is the first time I have seen this subject mentioned in a video and it is extremely important. Severe and permanent nerve damage has been caused to folk from the static build up in PVC extraction systems.
The ubiquitous Home Depot has 18 gauge bare wire (in USA). For some reason they note the voltage rating for bare copper, which I don't understand. Naturally, only the 500 foot spool is in my local store. Home Depot can be annoying.
I'm trying to understand the theory of operation. How many lightning rods did you use? How did you calculate the number needed per meter? If wrapping the pipe doesn't serve any purpose, why didn't you just run the wire in a straight line? Subbed up and liked. Thank you.
@@DavidStanton Apparently, the frequency of "rods" is insignificant. So I'll start with one in the middle and add as needed. The second one (if hair raising continues) will go between one end of the system and the one existing lightning rod, and so forth halving the distance each time. I'll see if I can determine how many per meter of ducting is required. Inquiring minds want to know.
Obviously having trouble with static in my shop or I wouldn't be watching your video. I've got a flex tube that arches from my drum sander to over to the main collection junction. I have to walk through the arch of the tube in order to turn on and off my dust collector. At first, I thought that I must have been walking through spider webs every time I got near the tube then I realized I had a serious build-up of static. It's not the discomfort so much but in my case, with very fine particles of dust the system isn't just a fire hazard under the right conditions but there is the larger danger of explosion. Thanks for the video, I've got thr information I need.
Great video. Clear and to the point. I have always wondered why wrapping it around the pipe when the static builds up inside caused by the rubing of saw dust on the tube. Shouldn't the screws inside the pipe pick up the static electracy? Just curious.

Thank You David, Excellent Video. You wrapped the fire around the pipe with one screw on one side and another on the other side. Are there other steps to grounding the pipes. Best Regards Dirk
Hi Dave, great video, hopefully you have an idea to help me. I am a floorsander by trade, i have my floorsander with a 50mm vacuum hose connected. 16.5 meters later it arrives at my Bona DCS 70 vacuum. Now, when sanding finer grit paper i get a huge static shock, do you have any ideas of how i get away from this with it being a normal vacuum hose, i.e., i'm not able to screw into it. Thank you
Festool make an antistatic hose for their dust extractors. The hose is carbon impregnated and where the hose connects to the dust extractor is a metal contact that runs through to the earth pin on the machines power lead. You can buy it by the metre up to 10 metres I think. Be aware it is very pricey. www.festool.com.au/products/accessories-and-consumables/dust-extraction/dust-extractor/hoses-cleaning-sets-connections/hoses-anti-static/50mm-antistatic-suction-hose-per-meter_452386
Yes. No cases of this to cite. Dust explosions require very fine dust, high concentrations of dust, and still air. Such as a nice, quiet grain silo that just finished filling. Woodshop dust is not that fine, moves very fast, and is in very low concentration due to the high volume of air. OTOH, you are hurting nothing by adding anti-static provisions except use of your time and money. The benefit would be to not be as likely to be zapped by the static.
Thank you for your time for your video it was very informative. I've seen a few videos like this and I have a question. If metal pipe doesn't build up static electricity why not just use metal?
I always hear of grounding pvc dust collectors, but have yet to ever hear of one igniting, exploding, or anything else anywhere, any time, or any place. You could also build a moat around your shop to keep the enemy from attacking.
Thanks luna! Did you watch the video and hear me say that I am not getting any zaps off the system anymore. Good idea on the moat, might start this afternoon!
Hey, that"s a great idea. Just out of curiosity, why do you still wrap the copper wire around the pvc? Couldn't you just go from screw to screw and save yourself from using so much copper wire? Are you putting screws on both sides of the pvc? Cheers.
Mark Radmall . The wire wrapping around the pipe ceates more surface on the exterior of the pipe to earth. Pvc is an insulator hence the outside needs grounding as well.
Great idea, thanks for sharing. Question, do you have to wrap the wire the total length of your vacuum pipe and any offshoots that you may have? thanks again, Tim
Hi Dave great job. The connector you showed in the video when you were connecting the wire it has plastic around it. do you have a source of them? And I don’t know why but when I clicked on your links to amazon some came up as Kreg clamps not the stuff related to the video of wire.
Interesting point 042forever. The kreg clamp is just a generic link I have to access Amazon. After you have entered amazon it is easy to do a search for a ground wire kit. The clips come with it.
I wonder if you considered using copper tape. You would have all the benefits of copper wire in a package that can be no more than 0.1 mm thick, self adhesive so easy to apply and you can connect to it either by soldering or by screw connection. Copper tape also relatively inexpensive.
Clifford Browning, I agree. The reason I have created this video is due to using smooth walled pipe to reduce the airflow interruption from the type of hose you mentioned.
Hi Dave! I’m sorry I’m week late asking, but I was wondering about the flex hose. Do you, or most folks, even worry with exposing a little of the metal coil and grounding that point? Or, is that just overkill? I’m very familiar with the opinion that static started fires in small shops are low risk, but I know from my electronics background that impact to tools with circuits is a real issue. Thank you for sharing your valuable wisdom!
Hi Dave, I have subscribed but I don't click the bell because I check your channel every 3 days and find your new videos then. I also don't want my email account filling up with notifications as I do watch a lot of channels mainly because I like woodwork and don't watch any TV. So if it is raining and cold out (most of the time in the UK) I resort to the videos. an interesting solve to the problem and neatly done.
Not a real expert here, but I'm guessing that the collector motor would be under-loaded and perhaps burn up. Oddly enough, running a blower with the intake closed will cause the motor to overspeed and die. IMHO, your idea would induce similar conditions. Again, I'm speculating here.
Hi Dave. Sorry, meant ground. In Aviation hangars we always talk about grounding and bonding the aircraft. Do you somehow ground the hoses themselves? Or do they benefit from the fact the PVC is grounded and they are touching the PVC at the coupling? Hope you’re well down under
Correct. In the average home workshop very rare indeed. If it is earthed correctly there is no chance. In the end it is up to you to be responsible for your own safety.
@@FPChris No offense but as an electrician I am familiar with two deaths from one in a million, rarely if ever or whatever. Both were ground related electrocutions of children.
Dave I do not understand why you had to spiral the copper wire around the pvc pipe. As you were earthing it at the euro screws why could you not lead the copper wire from screw to screw in a straight and direct line?
Hi Norman. The thing with static, just like lightening, is that it is random. The spiral application is a twofold thing. 1, to hold the wire against the outside more efficiently and 2, to give the earthing a better chance of catching a discharge because of the circumference thing as well as their is actually more wire used.
Another easy method to not have any significant surface to collect dust on the interior is to get a roll of aluminum tape used in HVAC duct work. It is cheap, provides a good surface area to collect charge, will cover any holes, and it will not provide anything for dust to collect on.
I recently set up a CV1800 with 6" pipe and am experiencing the same thing, hairs standing up when I'm within a foot or two of the pipes. What gauge wire did you use? And is it safe to assume you can just wire nut connections together to continue them when coming from a wye instead of using the connectors you did?
Hi Dave, Does this apply to all dust extraction hoses and PVC plumbing pipe alike? As I have just purchased the Carbatec DC-1200P from Tim in Sydney and about to work on my setup next week.
It depends Brad. If it is PVC then trying to ground the system is a good idea. If you have anti static hoses such as Festool have then you are good to go as long as the hose contacts the earthing wire. Think of it as an electrical circuit which is exactly what it is. Some carbatec 4 inch flex hose such as I have on the end of my pvc line as in the video has a wire as the stiffener. The grey hose does not, it is plastic.
Hey Brad. Thanks for giving Tim a 5 star on google. The company is pushing those kind of things within the ranks of the staff at present. It will make his day knowing that someone has taken the time to say what a helpful person he is!
Happy to do it, as someone in retail industry myself, we always hear the negative from customers and never get acknowledged for the good we do. I was back in store today with Tim and as usual great service... Now I just need to set up my new Carbatec 14" Bandsaw when it cools down. :-)
Dave, how long are the 5mm screws you used? I need to do this with my 6" PVC for the same reason, hairs always stand up as I walk by. Gets really annoying after a while.
what is with the ear protection when all you're doing is drilling a few holes into pvc. Stop that. You said that the wire you installed has an insulator, but it prevents static just thru the screws or did you purchase bare wire or strip the wire of the insulator, or did you just strip the wire where it makes contact with the screws?
Hi Gino. You must be new to my channel. The earmuffs are the mount for my action camera. Never said the wire I installed has an insulator. Have another look.
Hi Dave .... just a bit of background :- the plastic ducting you are using is in fact where the static electricity is being built up in .. not the dust or wood shavings (their flow in the plastic pipe just generates the static). Therefore you are actually earth bonding the plastic so any static electricity is discharged to earth. The screws don’t HAVE to penetrate the plastic as such. No harm done if they do tho as in the way you have done it. The copper wire you use to connect the screws as in the way you have done it can have PVC insulation on it so long as at each point you have a screw, the screw is in contact with the copper. Again the way you have wound the bare wire is good as it is making extra contact with the plastic duct. You can buy flexible plastic pipe where a continues copper braid has been moulded into the plastic material and then is bonded to earth where the pipe ends. Very expensive tho! Well done on your system and for recognising it needs to be done. Dust is very explosive under the right conditions.
2 things if your putting in a metal screw that's on the inside and outside of the pipe I do not believe you need bare copper wire, just screw into the wire and in the pipe you shouldn't even ahve to wrap over the outside of the pipe. the wire should bleed off any statice energy if not then at every screw wrap the pipes outside this will be to short a run to cause enough static energy. to make a spark jump far enough. 2' between screws. I'd just use a 1/2" truss head self tapping screw.
@@DavidStanton Would need to charge a high voltage capacitor then use a transformer to step it down to useable, since the static is probably like 5000-10000V when you get a shock.
Hi Linrox. I know there are a lot of people who say that it is a waste of time but my own experience is that I have never once received a shock off the pvc or flexible hoses since I did this. Before it was every day and I was sick of it.
I don’t understand. You say PVC is insulated and you shouldn’t run wire on outside. But thats what you’re showing. And are your holes all the way through the pipe?
You say in your video; "Pvc is an insulator" and then you install a conductor in the Pvc. You better hope your ground never fails, you'll miss those static discharge shocks.
@@DavidStanton the screw might be removing the static from the direct area near the screw, that is all. Air is a pretty decent insulator, not as good as PVC pipe tho. Static can't travel much through the air, or along the PVC so how is this doing anything? th-cam.com/video/yA22kTtV4XI/w-d-xo.html
That's interesting! It sounds like you've got a solid setup with your PVC dust pipe. It's great to hear that you're not experiencing any static issues!

Be aware it is very pricey. www.festool.com.au/products/accessories-and-consumables/dust-extraction/dust-extractor/hoses-cleaning-sets-connections/hoses-anti-static/50mm-antistatic-suction-hose-per-meter_452386
Great for stopping static from zapping you. But it's a myth that static causes explosions in small shop PVC dust collection systems.
Interesting point sandmandave2008.
Yes. No cases of this to cite. Dust explosions require very fine dust, high concentrations of dust, and still air. Such as a nice, quiet grain silo that just finished filling. Woodshop dust is not that fine, moves very fast, and is in very low concentration due to the high volume of air.
OTOH, you are hurting nothing by adding anti-static provisions except use of your time and money. The benefit would be to not be as likely to be zapped by the static.
@@genebruce6321 that is a very interesting point.
Thank you for your time for your video it was very informative. I've seen a few videos like this and I have a question. If metal pipe doesn't build up static electricity why not just use metal?
Hi David Thompson. Metal pipe is whole lot more expensive.
Metal pipe is a conductor; it will store static electricity into a nice big ole ZAPPP
Tks, i looking for one video like this for long time....
I always hear of grounding pvc dust collectors, but have yet to ever hear of one igniting, exploding, or anything else anywhere, any time, or any place.
You could also build a moat around your shop to keep the enemy from attacking.
Thanks luna! Did you watch the video and hear me say that I am not getting any zaps off the system anymore. Good idea on the moat, might start this afternoon!
Big issue in Saw mills
Hey, that"s a great idea. Just out of curiosity, why do you still wrap the copper wire around the pvc? Couldn't you just go from screw to screw and save yourself from using so much copper wire? Are you putting screws on both sides of the pvc? Cheers.
Mark Radmall . The wire wrapping around the pipe ceates more surface on the exterior of the pipe to earth. Pvc is an insulator hence the outside needs grounding as well.
Great idea, thanks for sharing. Question, do you have to wrap the wire the total length of your vacuum pipe and any offshoots that you may have? thanks again, Tim
Probably a good idea if you want it to be effective in those areas.
Hi Dave.
What's the brand and model of the extractor/impeller that you have? Sorry if you have mentioned it before.
Hi Dave great job. The connector you showed in the video when you were connecting the wire it has plastic around it. do you have a source of them? And I don’t know why but when I clicked on your links to amazon some came up as Kreg clamps not the stuff related to the video of wire.
Interesting point 042forever. The kreg clamp is just a generic link I have to access Amazon. After you have entered amazon it is easy to do a search for a ground wire kit. The clips come with it.
042forever try the link that is with the video. amzn.to/2M9ukWQ
I wonder if you considered using copper tape. You would have all the benefits of copper wire in a package that can be no more than 0.1 mm thick, self adhesive so easy to apply and you can connect to it either by soldering or by screw connection.
Copper tape also relatively inexpensive.
I see Peter Millard of 10 min workshop using copper tape inside pvc pipes.
This works but they do make hoses with grounding wires inside the walls of the hose
Clifford Browning, I agree. The reason I have created this video is due to using smooth walled pipe to reduce the airflow interruption from the type of hose you mentioned.
Hi Dave! I’m sorry I’m week late asking, but I was wondering about the flex hose. Do you, or most folks, even worry with exposing a little of the metal coil and grounding that point? Or, is that just overkill? I’m very familiar with the opinion that static started fires in small shops are low risk, but I know from my electronics background that impact to tools with circuits is a real issue. Thank you for sharing your valuable wisdom!
Hi James. I reckon that is a pretty good idea!
Hi Dave, I have subscribed but I don't click the bell because I check your channel every 3 days and find your new videos then. I also don't want my email account filling up with notifications as I do watch a lot of channels mainly because I like woodwork and don't watch any TV. So if it is raining and cold out (most of the time in the UK) I resort to the videos. an interesting solve to the problem and neatly done.
Thanks John. I know you have been subscribed for quite a while!
What do you think of aluminum tape to line the inside of the pvc pipe as a way to avoid static - I tried this and no statick
If it works for you, why not.
Do you thing a furnace blower at the end of the pvc run would boost the suction power of a dust collection system
I think it may cause more problems than benefit Thunderarrows.
Thanks from the otherside of the planet. Detroit Michigan, usa
Not a real expert here, but I'm guessing that the collector motor would be under-loaded and perhaps burn up. Oddly enough, running a blower with the intake closed will cause the motor to overspeed and die. IMHO, your idea would induce similar conditions. Again, I'm speculating here.
Hi Dave. Did you not find it necessary to bond the 4” expandable hoses? Or does doing the PVC take care of that? Thanks
Hi Adam Coe! Bond?
Hi Dave. Sorry, meant ground. In Aviation hangars we always talk about grounding and bonding the aircraft. Do you somehow ground the hoses themselves? Or do they benefit from the fact the PVC is grounded and they are touching the PVC at the coupling?
Hope you’re well down under
How common are explosions in a pvc collection system? I just heard about this phenomenon today.. It's gotta be one in a million right?
Correct. In the average home workshop very rare indeed. If it is earthed correctly there is no chance. In the end it is up to you to be responsible for your own safety.
Not very. if ever. Rockler has an article on it.
@@FPChris No offense but as an electrician I am familiar with two deaths from one in a million, rarely if ever or whatever. Both were ground related electrocutions of children.
@@deediddy Which has what to do with low levels of dust in a home wood shop?
I would use metal duct pipe for I think it is better to ground than pvc pipe.
Hey Dave. About to revamp my shop dust collection. Is this solution still working well for you?
Brilliantly James!
Thanks Dave. Keep up the great work on the channel!
Dave I do not understand why you had to spiral the copper wire around the pvc pipe. As you were earthing it at the euro screws why could you not lead the copper wire from screw to screw in a straight and direct line?
Hi Norman. The thing with static, just like lightening, is that it is random. The spiral application is a twofold thing. 1, to hold the wire against the outside more efficiently and 2, to give the earthing a better chance of catching a discharge because of the circumference thing as well as their is actually more wire used.
Another easy method to not have any significant surface to collect dust on the interior is to get a roll of aluminum tape used in HVAC duct work. It is cheap, provides a good surface area to collect charge, will cover any holes, and it will not provide anything for dust to collect on.
Thanks Nick Michels! Still needs to be taken to an earth point and does not work on the inside of the pipe.
Hi Dave, perhaps a simplistic question however, is there any loss of pipe pressure or air leakage at the euro screw points?
I don't think so Peter. The screw cuts in deep to the wall of the drilled hole.
Thanks David - great info that comes from Aust perspective.
I recently set up a CV1800 with 6" pipe and am experiencing the same thing, hairs standing up when I'm within a foot or two of the pipes. What gauge wire did you use? And is it safe to assume you can just wire nut connections together to continue them when coming from a wye instead of using the connectors you did?
I used the wire in the grounding kit I link to. Re connectors, what ever works for you. I had these connectors so I used them.
Hi Dave,
Does this apply to all dust extraction hoses and PVC plumbing pipe alike? As I have just purchased the Carbatec DC-1200P from Tim in Sydney and about to work on my setup next week.
It depends Brad. If it is PVC then trying to ground the system is a good idea. If you have anti static hoses such as Festool have then you are good to go as long as the hose contacts the earthing wire. Think of it as an electrical circuit which is exactly what it is. Some carbatec 4 inch flex hose such as I have on the end of my pvc line as in the video has a wire as the stiffener. The grey hose does not, it is plastic.
Sweet, thanks Dave
Hey Brad. Thanks for giving Tim a 5 star on google. The company is pushing those kind of things within the ranks of the staff at present. It will make his day knowing that someone has taken the time to say what a helpful person he is!
Happy to do it, as someone in retail industry myself, we always hear the negative from customers and never get acknowledged for the good we do. I was back in store today with Tim and as usual great service...
Now I just need to set up my new Carbatec 14" Bandsaw when it cools down. :-)
Dave, how long are the 5mm screws you used? I need to do this with my 6" PVC for the same reason, hairs always stand up as I walk by. Gets really annoying after a while.
Matt Przybylski, 10.5 mm
what is with the ear protection when all you're doing is drilling a few holes into pvc. Stop that.
You said that the wire you installed has an insulator, but it prevents static just thru the screws or did you purchase bare wire or strip the wire of the insulator, or did you just strip the wire where it makes contact with the screws?
Hi Gino. You must be new to my channel. The earmuffs are the mount for my action camera. Never said the wire I installed has an insulator. Have another look.
This could be any metal wire. Copper is a good conductor but for static the current is so low that steel wire would be fine.
Correct Jerry. People tend to think of copper wire when they are discussing electrical circuits due to a very slow corrosion rate.
I'll bet that you don't need to find bare copper wire. Use regular insulated wire and strip the insulation at the points of attachment.
That would work for the inside of the pipe at the point of the screws penetrating the walls but of no assistance to the outside of the pipe.
The PVC surely has virtually no electrical conductivity, so it cant be expected to 'flow' towards the screws. I think this wouldnt work.
If this is a real problem, why doesn't my whole house central vac professional installation have it?
Hi Jim. Did you listen to the opening of the video where I state what was happening with my system?
Hi Dave .... just a bit of background :- the plastic ducting you are using is in fact where the static electricity is being built up in .. not the dust or wood shavings (their flow in the plastic pipe just generates the static). Therefore you are actually earth bonding the plastic so any static electricity is discharged to earth. The screws don’t HAVE to penetrate the plastic as such. No harm done if they do tho as in the way you have done it.
The copper wire you use to connect the screws as in the way you have done it can have PVC insulation on it so long as at each point you have a screw, the screw is in contact with the copper. Again the way you have wound the bare wire is good as it is making extra contact with the plastic duct. You can buy flexible plastic pipe where a continues copper braid has been moulded into the plastic material and then is bonded to earth where the pipe ends. Very expensive tho!
Well done on your system and for recognising it needs to be done. Dust is very explosive under the right conditions.
Thanks for the compliment Steve.
2 things
if your putting in a metal screw that's on the inside and outside of the pipe I do not believe you need bare copper wire, just screw into the wire and in the pipe you shouldn't even ahve to wrap over the outside of the pipe. the wire should bleed off any statice energy
if not then at every screw wrap the pipes outside this will be to short a run to cause enough static energy. to make a spark jump far enough. 2' between screws. I'd just use a 1/2" truss head self tapping screw.
I have been wondering if a dust collector might be a fire/explosion hazard if something (a spark?) managed to ignite it?
Lots of things can, even a blunt router cutter can burn timber and catch in the air stream.
Surely, static elecricity only builds up on the outside surface - hence the use of Faraday cages - so it's unnecessary to put anything inside the pipe
My understanding is that the dust combined with the airstream travelling on the inside of the pipe also creates a static charge.
Should run the wire to some batteries to charge them for free. :)
Interesting point Chad D.
@@DavidStanton Would need to charge a high voltage capacitor then use a transformer to step it down to useable, since the static is probably like 5000-10000V when you get a shock.
I am surprised the wire did anything.
Hi Linrox. I know there are a lot of people who say that it is a waste of time but my own experience is that I have never once received a shock off the pvc or flexible hoses since I did this. Before it was every day and I was sick of it.
If it’s only the hair on your hands you’re concerned about you could try waxing . Just kidding great video.
Interesting point Renegade Dug.
Any ideas how to make a collector to collect plastic "dust" shrapnel and particulate from cutting PVC PIPE?
I don’t understand. You say PVC is insulated and you shouldn’t run wire on outside. But thats what you’re showing. And are your holes all the way through the pipe?
I think I mention all the holes are through the pipe. Watch the video a few times and it might become clearer?
David's university. Thanks.
Hahaha, thanks!
You say in your video; "Pvc is an insulator" and then you install a conductor in the Pvc. You better hope your ground never fails, you'll miss those static discharge shocks.
The screws are removing the static build up from within the pipe.
@@DavidStanton until the ground fails, then it becomes a conductor, and stores energy.
@@DavidStanton the screw might be removing the static from the direct area near the screw, that is all. Air is a pretty decent insulator, not as good as PVC pipe tho. Static can't travel much through the air, or along the PVC so how is this doing anything? th-cam.com/video/yA22kTtV4XI/w-d-xo.html
I have PVC dust pipe and experience no static.
That's interesting! It sounds like you've got a solid setup with your PVC dust pipe. It's great to hear that you're not experiencing any static issues!
The 240 volt wiring wouldn’t meet the regulations, bloody rough workmanship. Good idea on the earth bonding of pipe .
