Central Dust Collection – ALL-IN-ONE Woodworking Workstation – PART 7. Posted By Jean on May 18, Making the most of a small shop – PART 7. When I was designing my bench I envisioned it with a central dust collection system. A shop vac installed onboard was the most logical solution so I added my Bosch AdvanceVac 20 along with a simple homemade cyclone dust collector.  Installing a central dust collector to the bench involved fitting my shop vac along with my homemade cyclone dust collector in the small enclosure I allowed for it. From there I would relay the vacuum to where it was needed using an arrangement of hoses. One hose would be accessible at the top of the bench so it could be manually changed between all the equipment that needed it. The dust collection bucket needs to be checked frequently and emptied when full, so think carefully about logistics before locating a dust collector outside the shop proper. Be sure to plan for a way to turn the unit on and off remotely. And of course distance increases the length of ductwork, therefore airflow (CFM) may be lessened – so take that into account when sizing the unit.  The additional cost of a few PVC fittings will be a small part of the overall project cost and the return on investment via efficiency and ease of installation of an all-PVC network is significant. Should PVC pipe and fittings be glued together?  Popular Woodworking offers two publications on setting up shop and dust collection.

Having a mobile dust collection cart is a great way to step up your shop's dust collection. This dust collection cart has a minimal footprint. Where To Buy Workshop Dust Collection Systems. Workshop dust collection systems have become very popular with DIY and home workshops.  Dust Collection Parts & Network from Lee Valley Tools (Hoses, 4 Fittings, Hose Clamps & Mounting Brackets, /2 Fittings, Dust Collection Network, Loc-Line® Collection System, Self-Cleaning Blast Gates, Grounding Kit, Wet/Dry Vacuum Accessories). DIY Shop Vac Dust Collector. DIY Shop Vac Dust Collector: Like a lot of people, after retirement I built a woodworking shop.

A good system, however, will keep the broom and your lungs from wearing out prematurely. There are two main points woodworking dust collection parts visual consider when choosing 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 gisual hookups you are going to use: flexible hose, PVC pipe or metal duct. I used 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 woodworking dust collection parts visual 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 parta, 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 station them strategically in their shop. Woodworking dust collection parts visual 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 woodworking dust collection parts visual inside may occasionally move smaller chips upward. A filter bag hangs off to one side and collects the finest dust. Two-stage 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 longer 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 bisual bags hanging off to the side of the machine. Internal-cartridge cyclones use the least amount of floor space.

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 a small bit of metal, such as a screw, can cause a spark when it hits a steel impeller. Dust-collector explosions are rare, woodworking dust collection parts visual 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 will shorten its life. Woodworking dust collection parts visual dist to reduce the woofworking of fire is to choose a single-stage collector with a 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 woodworking dust collection parts visual, because of increased resistance, the air volume drops to under cfm, less than recommended for woodworking tools.

In reality, however, one coolection live with that. When I hooked up the 1-hp collector to a newly installed metal duct system, 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 woodworkiing oversized felt bags available from Oneida Air Systems that improve airflow and capture fine dustand I measured almost cfm. Hooked up to a 6-ft. Cyclones and two-stage woodworking dust collection parts visual have slightly more internal air resistance; 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 ft. A two-stage unit such as the Oneida costs almost twice as much. Penn State Industries also sells a woodworking dust collection parts visual 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 coplection 8 Woodworking Dust Collection Parts Ppt ft.

The Delta comes 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 woodworking dust collection parts visual at once Hooked up to two 6-ft.

When I connected the 2-hp units to the Woodworknig 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 woodworking dust collection parts visual, still acceptable woodworkimg 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 udst 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 woodworking dust collection parts visual 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 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 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 woodaorking facilitate reattachment somewhat.

The skirt and a woodworking dust collection parts visual 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 woodworking dust collection parts visual of dust collectors, I measured their performances under real working conditions, using woodworking dust collection parts visual hose, PVC pipe or metal duct in dst 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 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 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 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 parta 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 woodworkin material.
