Hello all, I am still in the building phase of my workshop. The electrical wiring is about 1/3 done. It looks like I might have to route my dust collection lines up to my ceiling from the DC (I have a 9’ ceiling and the shop is 22 X 26) and then to distribute the lines to the big tools. At this stage of the game I am still researching the big tools. As far as the DC is concerned is there help out there whereby you can get information regarding which DC will work based on shop dimensions, length of pipe, diameter, etc.? I don’t want to purchase one, only then to realize that it does not have enough power to do the job. Can anyone shed some light on this.

Regards,
Dan

Most online stores offer help: Penn State Industries, Woodcraft, Rockler. I have a Grizzly 2 hp cannister, love it and the price was right. It’s probably not big enough to support a big ducting plant though.

Hello Don, Actually, I thought I read it somewhere a long time ago that Oneida could provide that information if you give them your shop dimensions. Then they would recommend the type you need. Mind you, I have not checked their web site yet. I wanted to throw this out first, thinking someone knows a good solution to this. I realize too that there is a difference between running the hoses from the DC on the floor vs the ceiling. Thanks for the comment, I’ll keep that in mind.
Regards,
Dan

Buying the DC that’s right for you based on what others think is one of the hardest tool choice decisions IMHO. Everyone has their own opinion of what good DC is, and it’s almost always different than another persons opinion. Some guys are happy if the DC keeps the mess off the floor, others may have serious health issue requiring them to catch every possible spec of dust. These 2 extremes take very different equipment. If you find yourself on the “every spec” end of this, read some of the stuff at Bill Pentz's site, start with the FAQ section since there’s enough techno-babble there to give you a headache. If your closer to the other end there are some reasonable books available that would be useful, like the one by Sandor Naginsky (sp?). Pentz’s site is really a good source of info, I’d start there.

My shop is not done yet, but I work in it anyway.

I have a 4” duct to my table saw and a 2-1/2” duct to my 10” band saw, both open at the same time.

I can switch the 2-1/2” duct to my belt or disk sanders or to the drill press and I can switch the 4” duct over to the 6” jointer. I have a small 1hp dedicated collector for the router table I’m building that I might use on the lathe.

Space is essentially 23ft x 25ft with a 11ft x 12ft extension from one corner. Like a big L.
I am the only person working in this shop so I never use more than two tools together.

The HF 2hp on ducts and the small 1hp dedicated unit on the router works fine for me.

If I ever need more capacity I would add another 2hp HF machine just like my existing collector so I could still have the option of running one or both if that’s what I need.

What is more important than size of shop is the number of people working in this shop,
which tools are located where, and which tools you plan to run at the same time?

It is critical and fairly involved to calculate a system for balance and best effeciency.
HF will not provide that service because they do not have tech heads working in their stores. Some of their folks are challenged by the complexity of a cash register.

There are books and web sites with good info, or as suggested earlier, system manufacturers offer help.
I would find it un-ethical to get Oneida, for instance, to design my system and then buy from someone else.

Penn advertises sthat they will provide a dust collection layout if you ask for it. I would suggest a two stage system with a 6” dia main trunk. you can make drops to your various machinesd with 4’ dia pipe. I would also suggest pvc as collection lines even for the main trunk. pvc is available thru a plumbing supply house – the fittings also. From what I have heard, The Penn dust collection system is pretty good also.

I have 2 hp Grizzly with 8 foot ceiling, about 25 foot main run with 5 inch drops, it has preformed great for 3 years, my lungs have never had it so good. I also added a cieling hung unit for extra cleaning.

I have read a lot on Bill Pentz’s site myself. Currently we run a 2 hp Grizzly and we are very unhappy with the unit for what we need. We are a medium sized shop and need more results. I personally intend on following the advice from Mr. Pentz’s site as closely as I can. I plan to purchase the cyclone separator 18” diameter/6” inlet from a guy on ebay: http://www.ebay.com/itm/Cyclone-Separator-Dust-Collector-/270423194251?pt=LH_DefaultDomain_0&hash=item3ef67a7a8b and then I intend on purchasing a 5 hp leeson motor and the blower impeller and housing recommended on Mr. Pentz’s site. I basically intend on assembling my own cyclone as I am a DIY sort of guy. I do not want to build my own cyclone separator though, thus the reason for buying it on ebay. I am sure a home made 5 hp Leeson cyclone DC will be a huge upgrade.

and of course with us, everything is contigent on having the available funds. At this time the upgraded DC is ranked 1st on my list of upcoming purchases and as soon as we have the available funds I will begin the project. I anticipate completeing the upgrade around Feb 1st.

Hey Fred, After I posted this I found Bill’s site and I have to say that it was an eye opener. So I am going to continue reading on.

Hey Jerry, I have to admit that after reading Bill Penz’s article (so far only one) I got a different perspective on DC’s. What I was willing to spend on a dust collection system, I am going to re-think. Now my outlook is to spend more money on something a whole lot better. With me though I am the only one in my shop, so there is only one tool and DC on at a time. Thanks.

Hello Bugz, When you said your lungs never had it so good. How do you know that your lungs are ok? Is this a case that the long term of woodworking might prove something different? What do you think?

DC is an art unto itself. I use the HF unit with good bags as my primary collector with a 4” hose that can be moved to tools as needed. For permanent setup with blast gates I would use a much stronger DC and bigger ducts. Ya gotta go with what ya can afford. It can get pricey, but the expense is worth the effort.

Like the previous post I also have the Harbor Freight 1.5HP DC. I added the Wynn Environmental aftermarket filter and use that instead of the cloth bag and have a cyclone can lid on a galvanized can to catch the big pieces before they reach the DC. Price was a consideration plus the HF got good reviews. Was able to pick it up on sale and use the 20% coupon which fit right in my price point. My workshop is 1/2 of a two car garage so most of the machines are on mobile bases and get moved into place when needed. I have one 4 inch hose that reduces to a 2.5 inch which connects to the table saw, planer and band saw. The router table is smaller so I use the shop vac for that. It gets a little tedious some days if I don’t plan out the steps right but hey it works and I don’t have dust flying all over the place any more.

Nice looking shop, Bugz I have to admit that I don’t really understand the system… I have a single stage 2 hp Grizzly that does not do all that great a job. I would like to go to a cyclone type unit. Suctionwise, there seems to be no difference betrween a 2 hp single stage and a 2 hp cyclone I need to understand this system more before I jump!

Dont forget that the only thing a separator does is get more stuff in easily emptyable containers. It doesn’t get any more stuff out of the airstream. A cyclone, a Thein baffle or a simple trash can separator all just separate wood particles from the air

The separator has one other advantage, it can prevent big chunks from hitting the impeller.

What you worry about in a separator is:
a) How efficient it is – how much the air stream is affected by the presence of the separator. A properly designed cyclone is much better, a lousy cyclone could be somewhat better or about as good as a Thein separator, and a plain trash can separator isn’t so great
b) How much junk it gets out of the air stream – leaving the rest for the filter. Same order as above, but the Thein is a pretty good – you don’t see much more dust in the filter than in a highly efficient cyclone.

A good filter is a MUST. Get a .5 micron filter no matter what system you get. It matters to your health, a lot.

CFM is tied to horsepower and impeller size. Penz wants you to have 5HP and a 15” impeller. That mates to a 6” main line and 4” drops. A 2HP can’t pull enough air to drive a 6” main. It might work okay on a 5” main but that is hard/expensive to find, so most use a 4” main with 4” drops.

In all ductwork, you minimize flex (like none if you can), and use Ys instead of Ts, and 45s with a short section of straight pipe, or wide radius elbows. It does seem to work to use a single 10’ section of flex with the HF 2HP if that is all you have. Of course with fixed ducts you use blast gates to close off all but the parts of the system you need.

I have the 2 hp cyclone, with 25’ of 7”main line and 5” drops. I have to leave 2 blast gates open to get enough flow, it just seems work better. The cyclone is noisy, My shop is all concrete, as it is under ground garage, with one side daylighted for door. So the concrete interior dosn’t soften the noise any. With the cyclone running as i work, and vacumn on sander, and using good practices of dust control on tools, there is no fine dust accumilation on my table saw table. That is what sold me on the cyclone. I have never plugged my system, as others have that problem. My planer and jointer are the first drops, that seems to help also. I try real hard to stay away from MDF/Melamine products, if I can’t I wear a mask. Not tring in the least to say I have the best system, but it works for me in my one man hobby shop. Get the best you can, within your budet. It has taken many trades up to get fairly decent shop, that was the best part of the trip.
