Magazine Subscribe Magazine Customer Service. Begin by assembling the unit — it is easy to build. With more suction, there are more wood chips and dust from your miter saw being sucked up. Either buy one used from someone who has recently upgraded there are lots of them out there in my area or buy one aoodshop has enough power to collect from a ducting system if diy small woodshop dust collection tube decide to add that later.

Instead, look at the intake port sizes for the collectors you're considering. Most cyclones have intake ports of 6" to 8", and some two-bag collectors have 5"- or 6"-diameter intakes, so consider at least a 5" main duct. Tapered reducers, like the one below, change duct diameters with minimal static-pressure loss.

DO smooth out sharp curves. Think of air molecules as fast-moving cars on a freeway. The PVC tee shown at near right adds more airflow resistance than the metal dust-collection pipe's gradual bend. DON'T overuse flex hose. Corrugated tubing creates three times more static-pressure resistance than the same length of smooth pipe. Use just enough to link a tool to its drop pipe. DO eliminate bottlenecks near the collector.

See "Give dust a straight shot to the collector" below. Better still, raise the collector until the main duct leads straight into the inlet.

If you already have PVC, at least run a bare copper wire along the outside of the duct to ground. It would be better if it was on the inside, but this is not always practical. In many areas it is strictly against code to use PVC for this purpose. Good luck, and work Diy Small Woodshop Dust Collection Joint safe. Here is an example if instruction from Shop Fox, a popular portable dust collector manufacturer.

System Grounding. Ensure that each machine is continuously grounded to the dust collector frame with a ground screw, as shown in Figure While I agree with most of your article, I strongly caution any use of PVC pipe in a wood dust collection system. Just because you may not have had any issues in the past does not mean that you are capturing the dust safely.

My suggestion is to use only metal duct, make sure the dust collector will provide 4, Fpm feet per minute velocity in the duct and only capture wood dust with your dust collector. These simple steps will drastically reduce your dust explosion risks. Love the system but for one thing: Insurance companies Pretty sure every single one of them will not cover a house fire if there is a non metallic DC system and they can claim that the fire started there. They allow no substitutions like ground wires straps etc.

They only cover metal ducts that are grounded. What are the odds that a DC will cause a fire? Maybe remote. PVC duct systems are common in hobbyist woodworking shops but users are encouraged to perform their own due diligence to verify their insurance coverage. Love your DC. Love your approach. I learned that no insurance company will cover a fire that they can claim arose from a dust collection system not made from grounded metal piping.

Put aside the whole fire risk or not question and ask the other question of insurance coverage. The problem is that insurance companies have an unshakable conviction that non metal ducting is an unreasonable fire hazard. You answered several questions I had about setting up a dust collection system in my shop. Tahnks for writing the article, it was very good for me. I dont know if you can answer my question. I want to make piping for my cfm dust collector. At the output of the collector, there will be 2 lanes.

The left lane will be on 4 inch pvc duct for about 14 feet with about four 45 degrees elbows. The right lane will be on 6 inch pvc for about 30 feet with a 5 feet of vertical duct on the 30 feet with about four 45 degrees elbows. At the end of the 30 feet, it will have about 16 feet of 4 inch pvc to reach the tools. Only one tool at the time will work on this collector.

Can you tell me what dust collector this is? Would such a small system work, in your opinion? Hi Jim. It would collect some of the heavier debris but would not do much to collect the fine dust that causes health problems. I would recommend at a minimum a 1.

I incorated 12 v switch system to start the system automatically. Use metal pipe with whatever fittings you choose to afford and make sure to ground it in at least one place. Blast gates are setup at each tool, and you only have it open when you are using that tool; all other gates remained closed.

That provides the full concentration of suction right at the tool you are using, to get you maximum dust collection from that tool. If you left all of the gates open you would have very poor air flow at each tool. Hi Rick. Hi Timothy. Wish I had read a a long time ago.

I have learned all this and more by going it alone with my first system. On my third now and it works great. Not quite done yet but what a difference hen you get big pipes and a powerful blower. John the Handyman in Las Vegas. I have an 8 foot stroke sander as well as a small belt sander and blow up sander, would I need to run separate runs to each of these.

They are side by side in my shop. The stroke sander is the worst tool for dust and not sure what is the best way to set up the collection piping on it. I am in the country with a bush beside my shop so I plan on piping directly to the out side with the out let. Hi Ron. Thanks for reaching out with your questions. I would recommend a separate drop for each tool. In other words, you are better off if you have a single blast gate designated for each tool, and therefore each tool gets the full air flow from the dust collector.

For the stroke sander you will probably want to build a shroud of some sort, and position it directly behind where the dust flies off on the left end as you face the machine. I would build a shroud, or buy one, and experiment with positioning it. Great article. After much research about metal vs. Although my shop is in the painting stage, I can assure you I will be implementing the ideas in this article.

I have a Clearview cyclone can I run the dust container off the bottom at a 45 degree to a barrel Diy Small Woodshop Dust Collection Matrix outside the wall. I would think so, but I would suggest contacting the folks at Clear Vue with this question to be sure. Thank you for all the great information.

I got a great deal of information. Thank you. I combined a cyclone with a bag style dust collector and placed both in the room next to my shop to keep the noise level down. I placed a blast gate at each machine along with a pushbutton start stop station.

Velocity is high enough to move dust as well as planer chips and lathe shavings. To prevent static charge and shocks I lined the PVC and fittings with a strip of aluminum foil duct tape with the ends wrapped around the pipe ends and fitting ends so that continuity is maintained from the machine all the way to the dust collector which is electrically grounded. And if you were using a four inch line a low cost take off is the plastic end caps found in rolls of carpet at your builders supply.

Paul, thank you for some very helpful advice. I searched the internet and read books to do the best I could and I see I managed to get some things right. After years of searching the plumbing depts for fittings to connect different tools I now look at how a tool will connect BEFORE I buy it and sometimes buy the brand that put more forethought into connecting to my dust collection system.

I disagree with your suggestion of using screws whenever possible to secure joints. The sharp point and threads of the screw inside the ductwork will tend to catch and hold onto small pieces of wood chips that can build up over time. If using PVC, why not cement them together? If using metal, as I did, try using pop rivets instead of screws.

Then make sure to seal the joint with aluminum tape. When comparing types of material for my dust collection pipes, my local plumbing store recommended dryer vent pipe. This seem to make excellent sense when they explained PVC is meant to move water a heavier substance and dryer vent pipe is specifically designed to move air a lighter substance.

What are your feeling? I would think that the speed that the air flows through the pipe and dragging the dust with it would be a better standard. True, a large pipe has less resistance, but a smaller pipe allows for faster air travel through the pipe. If it drags the air from the tool at the far end of the system it should be adequate to move the dust through the rest of the pipe. You must have a very large air movement system.

Also do not discount air restrictions after the power. A simple system like a shop vac has a bag to collect the dust and provides a large restrictive force. I live in the country and can exhaust my dust directly outside without the catch bag restriction. I have a big harbor frieght dust collector for the big machines. For the smaller machines I use a big shop vac! I dont need to do all that piping and nothing is in the way!

I just bought a dust collector with 4 in. I enjoyed the topic of dust collection system, I like to know more to see if I can design my own systems. I know how much dust woodworking produces, even with hand tools, and I love to read and hear other ideas on dust collection systems. A remote control really helps.

An old shop vacuum barrel collects the dust and chips under the dust deputy. I have emptied the barrel a couple of times and only have a trace amount of dust in the DC bag.

They sell plastic hangers for the ABS pipe that is convenient to hang my pipe, instead of attaching the plumber straps. Your advice on tees and y pieces is wrong, the ones you say to pick are more turbulent and add more static to the system over the ones say to not pick.

Using the ones you say NOT to use will allow the air system to operate more efficientl. I think you should either get a bigger dust collector, or figure out a way to have shorter duct runs. Reducing the ducts at the drop will give you faster velocity at the tool, but it will slow down the overall velocity in the main trunk where you are already struggling.

Helping my son set up a wood shop in a makerspace. He has a Delta cfm, 2hp, 8 in-H2O static pressure drop. Problem is, the wiring is all done for the DC in a certain place in the shop. Any thoughts? Hi Ted. I would relocate to shorten the lengths if possible. I know this from experience. Thanks Paul-Woodworkers Guild of America. There are four tools. The table saw is farther away, and the chop saw is a bit farther.

Does that sound better? Does that make sense? In answer to your first question. Yes, that sounds better. For your second question. By Woodness Goodness Follow. More by the author:.
