Over the last eight years we've documented hundreds of home improvement and DIY craft projects along with many tool and material reviews.

Remember the FPM for wood dust in branch lines is Identify your primary or high-use machines. These are the machines that operate simultaneously on a frequent basis. The objective here is to define your heaviest use scenario so you can size your system to meet it. Including infrequently used machines and floor pickups in your calculations will only result in an over-designed system that will cost more to purchase and to operate.

At this point, all of your branch lines are sized, and you have a list of all components required for your branch lines. Now you are ready to size the main trunk line. Begin with the primary machine that is furthest from where you will place the dust Table Saw Primary Radial Arm Saw Dust collecting unit. Note: If a non-primary machine or pick-up is added to the system between primary machines, the size of the run is not increased. This not only assures adequate air flow but also anticipates a future upgrade in machine size.

In this step, you calculate the Static Pressure SP or the resistance of your system that your dust collection unit must overcome. To do this you total the Static Pressures of the following system component groups:. Calculate the SP of all branches to determine which has the greatest SP. Only the branch with the greatest SP or resistance is added to the total. You can use the charts on pages to assist in your calculations. You now have the information you need to specify your dust collector. The above example is for a small system with few variables.

It is recommended that for larger systems a professional engineer be consulted to assure that the system is properly designed and sized. A 2-hp unit can sometimes handle two machines at once Hooked up to two 6-ft. When I connected the 2-hp units to the PVC duct system, they too were robbed of considerable power, but one machine could be operated at a time with satisfactory results.

When connected to a metal duct system, the Jet collector really moved a lot of air, cfm at the tablesaw-jointer connection after about 25 ft. With two blast gates open, the air volume was reduced to less than cfm, still acceptable for some operations. The Dust Boy produced slightly lower readings but still had more than enough power to run one tool at a time in any configuration.

If you regularly operate more than one machine simultaneously, it would be wise to look at 3-hp or bigger dust collectors. They cost more, however. Most 2-hp collectors come wired for volts. The Dust Boy can be run at either volts or volts. On the matter of choosing a dust collector, a two-stage cyclone gets my top vote. A small cyclone collector takes up less room, is easy to empty and runs very clean.

For example, on all of the single-stage units, even after running them for only an hour, fine dust appeared on the machine and in the area around it. The Oneida cyclone, outfitted with an internal filter, rubber gaskets and wide metal ring clamps, seals better.

Two-stage units such as the Dust Boy Delta also makes a two-stage collector are also nice and compact. The Dust Boy takes up 6 sq. The Dust Boy as does the Oneida comes with a Leeson motor and cast-aluminum housing and impeller fan , and the sturdy plastic barrel holds a lot of debris, 55 gal. Before it can Shop Dust Collection System Diy Jacket be emptied, however, the heavy motor and housing must be lifted off.

Removing the lower bag of a single-stage collector is an easy matter of loosening a band clamp. The real fun begins when you try to reattach it. The lower bag must be wrapped around the metal waist of the machine and held in place before the clamp can be cinched. Some manufacturers, such as Jet, add an elastic band inside the lower bag to facilitate reattachment somewhat. The skirt and a standard gal. I just wish the skirt were made of felt rather than the more porous woven fabric. This setup will reduce the air volume.

When an ad says a collector is rated at 1, cfm, what does it mean? Not much, really. Cfm stands for cubic feet per minute, a measure of the volume of air moving past a point of reference. The cfm figure needs to be put in the context of the amount of resistance, or friction, present called static pressure, or SP. Air moving through duct or hose encounters resistance, just as a person would slipping down a water slide.

The more bends and bumps, the slower the ride or the lower the air velocity and volume. Many manufacturers rate their machines without bags or duct attached. While trying out a number of dust collectors, I measured their performances under real working conditions, using flexible hose, PVC pipe or metal duct in my sq. I also measured collectors hooked up to a straight piece of 6-in.

Collectors ranging in size from 1 hp to 2 hp have impellers fans sized from 10 in. All things being equal motor speed and impeller design , a bigger impeller coupled with a bigger motor will move more air than a smaller pairing.

There are some differences among collectors; to learn more, ask a manufacturer for an impeller performance chart. As soon as any collector is hooked up in the shop, performance declines in relation to the length and type of hookup. Materials that affect airflow. The metal elbow top , which is designed for central dust-collection systems, has a gentle sweep, which lowers resistance to airflow.

Plastic PVC pipe has a tighter-radius bend and restricts airflow more. Ribbed flexible pipe also disturbs airflow, up to three times as much as metal. Hooked up to two 6-ft. With a larger upper bag, I found that the cfm readings were not compromised. But if you happen to vacuum up any offcuts, they will make quite a racket rattling around in a metal trash can.

Although many woodworkers, myself included, have used PVC drainpipe for duct without mishap, experts warn against using the material. The connectors elbows and wyes restrict airflow, and the material builds up a static charge, which may cause a spark and set off an explosion.

Running grounded copper wire inside the pipe reduces the hazard. Do you have a price estimate for how much you spent on this? Thanks and great post. Keep us updated on how it works in the long run! How did you seal around the pipe penetrations in the ceiling?

I was only able to source locally from Rockler. I have dust collection on my TS too but I still get some above the table even though I always cut with the guard on. Maybe a ZCI would help. There is some slight movement so whatever I do will need to be flexible. Any suggestions? I got all my odds-n-ends including the reducer off Amazon.

I get a very small amount of dust above the saw too. Perhaps a ZCI is a good move. Great DC system Ethan! I recently sold a unit I had for a while before we moved. Good use of PVC and the grounding wire to protect you from shock.

Clever solutions! Wow, this is a serious system. Dust collection is quite important, in my opinion, regardless of how much you use your shop. Protecting your lungs is priority one. Really nice setup. It feels like have a dust collection system takes you to the next level and commits you to a shop floor plan layout. I have never seen the floor sweep but that sounds like a really handy idea. Should we be expecting any plans or knowledge sharing of shop pneumatics?

Thanks again. Running pneumatic is best to run a 1 inch line or larger for the main trunk then reduce coming off of that if necessary. If you can run 1 inch to all your connection great psi is good but without volume of air you lose power just as fast.

Cool reminds me of shop class except that dust collector was huge. Will keep that workspace looking nice for you. That system is pretty awesome. I would love to have one in my shop but my shop is also my garage. This Commercial Woodworking Dust Collection Systems Zip means that the same place I park my Jeep and motorcycle is where I work on them.

It gets old always having to move a vehicle to work on stuff, but until I can afford a bigger place it will do. I will just have to stick with a shop vac and dust masks. I used to have that very dust collector and loved it.

Worth every penny. What happened to it? You never expect to lose a DC to a garage fire. Do you know how it started? Another great job on the walkthrough! Keep up the great work OPC! Great site Ethan. When you screwed through the pvc pipe into the blast gate flange, did you predrill holes in the aluminum or is the force from the screw simply holding the gate in place Small Shop Dust Collection System Editor without actually Shop Dust Collection System Diy 02 going into the gate?
