During this whole dust collection series, I haven’t had to buy any wood. Admittedly, my sheet storage bin was overflowing with leftover plywood from various projects. ½-sheets and ¾-sheets a-plenty.  You mentioned that you want to set up collection for scroll saw work. This dust is usually quite fine and is in very small quantities. I think that your idea to use a vacuum and a small cyclone separator is spot on. See more ideas about dust collection, woodworking, shop dust collection.  I have a Delta contractors saw, which was obviously never designed with much dust collection in mind. I built a dust pan out of sheet metal with an angled.

This sucked. Literally. Imagine cutting boards and then leaving the room, closing the door, and waiting for the dust to settle. It wasn't a good way to encourage more shop time. So let's assume you want some sort of dust collection system even if just eventually.

A good system, however, will keep the broom and your lungs from wearing out prematurely. There are two main woodworking shop dust collection design to consider when woodworking shop dust collection design a dust collector. First, figure out the air-volume requirements of the machines in your shop see the chart on p. Next, decide on what kind of hookups you are going to use: flexible hose, PVC pipe or metal duct. I woodworjing the collectors with my tools, which include a in.

The horsepower rating is a fairly reliable guide to the performance of a dust collector see the chart on p. Hookups, however, are everything. Too much flexible hose will rob even a big collector of power. Metal duct, not unexpectedly, performs best.

Even an 8-year-old, 1-hp col-lector can collect chips from machines 25 ft. Every shop is different, of course, and your results may vary, so use my findings as guidelines, not absolutes. A 1-hp single-stage collector can handle any machine in my shop The biggest sawdust producer in my shop is a in. And even a 1-hp singlestage dust collector can handle that machine, hooked up with about 6 ft. I borrowed a new UFO, same as my old collector, to see if anything had been changed.

Some woodworkers buy two units and wooodworking them strategically in their shop. At 82 decibels measured at 8 ft. The most economical and biggest-selling dust collectors are the two-bag, single-stage models. Single stage means the dust is sucked through the impeller fan and dumped into the lower bag. The upper bag collects fine sawdust and lets the exhaust air back into the shop. Two-stage collectors are the next step up.

The motor and impeller sit atop a barrel. Chips enter the barrel and are directed downward, although the swirling air inside may occasionally move smaller chips upward. A filter bag hangs off to one side and collects the finest dust. Xollection cyclones are at the top of the evolutionary chain. The motor and impeller sit atop a cone-shaped canister, the cyclone, which is connected to a trash can below. Chips or other large debris enter the cyclone and swirl downward, avoiding the impeller.

The woodworking shop dust collection design the cyclonic chamber, the greater its effectiveness at slowing down and separating large particles. Air is filtered either by a pleated internal cartridge or by one or more felt bags hanging off to the side of the machine. Internal-cartridge cyclones use the least amount of floor co,lection. The upper bags or cartridge filters of all collectors must be shaken out occasionally to remove fine dust.

Debris entering a single-stage collector passes through the impeller, many of which are made of steel. Even shlp small bit of metal, such as a screw, can cause a spark when it hits a steel impeller. Dust-collector explosions are rare, but the potential is there. Debris, metal or otherwise, not only makes a racket when it hits an impeller but also imparts stress on the bearing and collecfion shorten its life.

One way to reduce the risk of fire is to choose a single-stage collector with woodworking shop dust collection design plastic or aluminum impeller. Steel impellers are fine, however, if you avoid using the dust collector to sweep up miscellaneous debris off the floor or workbench. I also used the 1-hp collector with a PVC duct system 4-in. At that distance, because of increased resistance, the air volume drops to under cfm, less than recommended for woodworking tools.

In reality, however, one can live with that. When I hooked up the 1-hp sbop to a newly installed metal duct system, Woodworking Shop Dust Collection Design 10 with my tools in the same configuration as before, I was really surprised.

The air volume was back up to cfm, very acceptable. Then I hooked up my old 1-hp collector, which is outfitted with oversized felt bags available from Oneida Air Systems that improve airflow and capture fine dustand I Woodworking Shop Dust Collection Design 3d Model measured almost cfm. Hooked up to a 6-ft. Cyclones and two-stage collectors have slightly more internal air woodworking shop dust collection design hence the lower cfm reading. Performance ranged from good to so-so, depending on how much sawdust was being spit out by my tools.

The best way to direct maximum airflow to the tool being used is to attach a blast gate to each hose. Hooked up to a PVC duct system a run of about 25 woidworking.

A two-stage unit such as the Oneida costs almost twice as much. Penn State Industries also sells a cyclone collector. With two blast gates open, the air volume dropped and was insufficient to operate two big machines at once. More horsepower does mean more noise; both registered 85 decibels at 8 ft. The Delta comes Woodworking Shop Dust Collection Design Uk wired for volts but can be switched over to volts. The Oneida comes without cable or switch. It can be wired to run on either current. 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 Woodworking shop dust collection design duct system, they too were robbed woodworking shop dust collection design 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 woodwroking 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 woodworking shop dust collection design 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 collsction. Two-stage units such as the Dust Desogn Delta also makes a two-stage collector are also nice and compact. The Dust Boy takes up 6 sq. The Collectioon Boy as does the Woocworking comes with woodworking shop Woodworking Shop Dust Collection Design Github dust collection design Leeson motor and cast-aluminum housing and impeller fanand the sturdy plastic barrel holds a lot of debris, 55 gal.

Before it can be emptied, however, the heavy motor and housing must be lifted off. Removing the lower woodworking shop dust collection design 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 woodworking shop dust collection design of the machine and held in place before the clamp collectiob 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 woodworking shop dust collection design 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. Woodworking shop dust collection design ranging in size from 1 hp to 2 hp have impellers fans sized from 10 in.

All things being equal motor speed and impeller designa 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 woodworking shop dust collection design 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.

Dexign that affect airflow. The metal elbow topwhich 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 woodworking shop dust collection design 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.
