Using PVC for Dust Sucker....:+}

[danny]

I know this subject has been posted before, but I just recently ran across it and

I just had to give it a go.  Been using the Fan blowing on my right across the saw

towards the square fan with filter for Ages.  This method Does work, but still will not

contain all the dust and lots gets by and all over the shop.  So I did follow anothers

design and have experimented with mine and I DOES WORK GREAT.  I am using a

Vacuum name BAD ASH VAC.  Only about half as loud as the normal Shop Vac. 

Am still able to hear my Music etc.  So....In clusion I want to say I wish I had of

run across this article Years Back.  Here is my set up.  I did discover while taking

these pics that Under the Saw table and surrounding areas Needs a Good Cleaning.  Anyway comments are Always welcome.  Danny  :+}

I set my hawk up the other week the same way but tied it into the dust collection system in my shop. One thing i noticed is the top vac does not suck as good as the bottom one does. I still need to use the blower to blow the dust towards the top vac. It may be an issue with the distance of pipe I needed for the 26" hawk. Piping is about a 1/4 on the bottom then on the top. I only have to run my shop vac about once every couple of weeks now instead of every day after cutting. Wife does not like me tracking the sawdust into the house.

Thanks for showing your setup - I'm going to be setting up both saws this weekend with dust ctrl and appreciate eveyone's pics of how they have theirs setup

My motto is - I don't care how it looks as long as it's functional

I have 2 dust ctrl systems in my small shop - a shop vac hooked up to my mobile tool carts

and my HF dust ctrl which is attached to my table saw and my main work bench which has become my scroll saw bench as well now.

And I send Thanks for the comments. 

Jes my you have a vacuum set up there for all your tools.  I like it.   Will use these pic's for thoughts about my lil shop.  Danny  :+}

Nice systems.. I also plan to run something like this once it gets warmer and i feel like tinkering with my set up more.. 

Any of you all running a ground wire on the pipes for the static? That fine dust and static is a big flash fire explosion waiting to happen.. My son is a firefighter.. and has seen this a few times... Maybe only an issue with cold dry climates we have ? not sure but I'll be grounding my system for sure..

The topic of dust explosions in home workshops has been debated hundreds of times on forums.  There have been no documented explosions that I have read about. 

I think using a vacuum on a scroll saw rather than a dust collector is the best way.  A dust collector only has about 8-10" of suction while a vacuum is typically 75-100" of suction.  The vacuum will do a much better job especially with smaller sized pipes.

A vacuum has high suction and low cfm.  A dust collector low suction but high cfm.

The use of flex hose either from a vacuum or dust collector lowers the suction. It can be a pretty significant amount.  Using smooth pipe is much preferred.

We'll I'll be.  Grounding Pvc is something I have never heard of.  Alth can understand the fact that Static zapper

could be present.  Need to do some checking on this. 

So anyway thanks again to All for comments.  For now I FEEL 99% OF THE DUST I HAVE CREATED LATELY

HAS BEEN CONTAINED IN MY Bad Ash Vac.  LOVE THAT NAME.  LOL                       Danny  :+}

I have my dust collection connected to ground.

[Sycamore67]

It is interesting try to ground a non-conductor.  You almost need to wrap the entire PVC with a conductor to completely ground it. 

[kmmcrafts]

There are many ways to ground the tubing.. I watched a couple of videos a couple days ago and I can't seem to find the one I really liked.. but at any rate here is a link to one method.. I'm sure there are quite a few videos out there on this..

I only have my planer hooked to my dust collection and this time of year you can see.. not to mention feeling the static arcing to me our my clothing if I get close enough to that tubing... which is why I plan to ground mine.. your systems may not have that much static going on.. but it gives a pretty good jolt when it gets me, LOL...

As I said earlier, this issue if exploded dust collect PVC in a home shop has been discussed many times.  The best explanation by an expert is this article.

Very nice job Danny. I am in the process of doing something similar to my Hegner so having your pics to look is very helpful. Keep up the great work.

I am sorry to try to say this again and you can just choose to ignore me.  

YOU CAN NOT GROUND AN INSULATOR LIKE PVC.  You can ground a metal pipe, a metal duct, a wire, a piece if machinery or any other metallic item.  PVC is an insulator and electricity does not conduct thru it.

If it makes you happy, ground anything you like.  Below is the link to the technical article about this.

I've see no documentation on dust explosions, but I have proven the static electricity. I had a couple of PVC pipes running in my dust system and was continually getting shocked. One day we put a pile of sawdust on the floor and started to vacuum it. I put my digital volt meter between the PVC and a socket ground. The meter maxed out at 9999.99 volts AC.

We opened the pipes and ran a piece of bare #12 copper wire down the inside and fastened the wire to the metal piping that ran out to the DC. That seems to have solved the problem.

I only use flex tube that has the metal spiral in it. I keep the flex tube as short as possible and trim enough to connect the metal spiral to the metal pipe or the screw, that connects the ground wire through the PVC.

When you are grounding your system, only ground one end. Either the DC end or the equipment end. Ground both can set up ground loops, especially between machine using different voltages. Ground loops are not nice and can hurt the electronics and motors in machines.

I see you have some long runs from your vac system and they seem to be out of plastic. Do you have them properly grounded? If not, wrap some copper wire around them and fasten to a good ground so you eliminate any chance of a kinetic spark starting a fire. Just to be on the safe side.

I have very few PVC pieces in my lines - it's all plastic - I know the spiral stuff is not the most efficient but it's what I have and so is what I use. i had like 50' feet of the stuff at one time

No need for me to ground anything though but thanks for the heads up

I have bare wire grounded in my pvc dc system.  Is it doing anything, I don't know for sure other than the fact it does not even collect dust on the outside of the tubing.  Russ

Hi Danny. I was amazed at the amount of sawdust on the underside of your Hegner. Wonder if it is static that keeps it there. I 'll have to look under the table of my Hawk and see what's there.
