Charlese:
I guess my mind is kinda tired this late in the evening but I can't draw any recollection of your reference to pg 310 of PTWFE out of my old memory bank.
I got the 330 cfp airflow figure out of Shopsmith's 2006 Mk V Accessory Catalog pg 15.
charlese
It says 107 CFM through 1 8' SS hose - With two hoses 100 CFM through each - with three hoses 97 CFM per hose.
So with the help of my math- 3 hoses means the machine is drawing almost 300 CFM.

charlese, in an earlier post on this thread, suggested that we use a product called Great Stuff on the protruding bolts in the dust collector to protect the plastic dust bags. I had another solution: When putting my DC3300 together, (recently purchased and after reading this thread), I inserted the bolts from the inside so the plastic bag rests against the round heads rather then the nut and spring washer. If the bags still tear out from the bolts, I will let you all know.:D

John, he that started this thread originally, was thinking that the DC3300 was a little pricey. Here is what I came to think about that:
I was looking to buy a dust collector too, and had come to the conclusion that the SS was too much money:eek: . Looking at other dust collectors out there, I found several that were cheaper and rated higher CFM. Then I thought about what you get with the DC3300: All those extra parts that allow the dust collector to be hooked up to your tools and used right now. Those other less expensive units came with nothing. I would have had to purchase quite a system, one that does not come cheap, to hook up my tools. I decided that the DC3300 was a bargain after all. And that was not even the best part. The DC3300 was offered in an e-mail special for $399, so I bought it. That special is over now, but they are now having a sanding sale and the DC3300 is being offered again at $399. I suggest that you jump on it:D .

This has been a long thread so I apologize if I'm repeating anything:
The 1 and 1 1/2 HP dust collectors that are priced lower than the DC3300 are equipped with canvas dust bags that can only capture dust to around 30 microns. You need to go below 10 microns in order to offer any protection for your respitory system. Thus the cheaper models are basically chip collectors. The DC3300 has a polyester felt bag that is rated down to 7 microns. The optional 24 or 42 inch upper bag takes this rating even lower - at reasonable cost. This is not a place to skimp on dollars. After all, the main reason we are purchasing a dust collector is to protect our lungs.
Also from what I have read so far is that the 1 and 1 1/2 HP units have noise levels in the 82 to 85 decibel range, probably about 10 decibels higher than the DC3300. Since decibel levels are logarthmic, this is a very noticeable difference. Dust collectors this size and larger have their place in larger shops where they are the key component in a permanently piped system. In fact, If I were to set up this type of dust collection system I would construct an enclosure outside of the shop's main wall to house the unit, mainly to keep it's bulk and noise out of the shop.
CFM ratings are somewhat iffy. If you have an adaptor that takes their 4 inch opening down to 2 1/2 inch the cfm will be much less. The length of piping and hose, and the number of bends in the piping system also has a great affect. The DC3300 is designed to be close to the machine and in this capacity it is just about the best small dust collector on the market.
By the way. on page 84 of "Small Woodworking Shops" Taunton Press 2004, author Jim Whetstone describes how to construct a compact ceiling mounted air filtration unit that captures dust down to a few microns. This would be a great addition to your shop even if you do have a good dust collector.

Sometimes - there comes a solution so simple - it is positively genius!!
Nice going Tim!! That solution never occurred to me at all.

Ahhh, shucks Chuck, it was nothing:o .

Tim:
After starting this post and looking at some of the other DC's, I agree that for my needs the SS one is a good bet. At $399 I would also jump at it.
Unfortunately the Canadian distributor does not seem to be offering the same packages that are offered in the States and the price here is $625. I will try him to see if he is willing to match the U.S. deal. Even with a sale, prices are 25% higher to allow for exchange, etc. .
Now maybe if I were in Vancouver I could make a deal with you to have it shipped to Seattle and pick it up, but it's a long drive from Montreal.
Thanks to all who offered opinions and suggestions on this subject!
Have fun woodworking!

If the Canadian dealer won't offer the sale price, another alternative would be to take a trip to Dayton when the weather gets a little nicer. It would be about 700 miles - a long day's drive. Take a vacation. You deserve it.
Shopsmith's retail store often has demo units on sale at a good discount with full warranty. You can call them first. You could also take a side trip to the Frank Miller Lumber Company which is about 50 miles NW of Dayton in Union City Indiana. This is a real "candy store" for woodworkers.

I have already started laying the groundwork for a trip to Dayton with "The Boss". My idea was to try and take in one of the Academy sessions while on a vacation. However that would not be until later in the summer but a visit to the store would certainly be part of the plan. I may have to find a way to seal my wallet though to avoid being tempted by all the toys as both funds and space are limited.

John,
If you figure a way to do that please let the rest of us know how you did it. I know that when I recently attended a Traveling Academy, Rick Davis successfully sold me on a lot of new tools:eek: . And with the freebies that are available, I just kept putting more items on the list:mad: .
john
Hi folks:
The Canadian distributor has come back with a price of $500 Cdn for the
DC3300 which is about in line for the current promotion after adding exchange for the U.S.$. That is about double what it would cost for one of the 1hp 600-700cfm units that are available up here. I would also have to buy sight unseen as I will be in his area in a couple of weeks but he dosen't seem to have one in stock.
Now I have to make a tough decision. My heart says go with the DC3300 but my pocket book says differently. Besides the price differential is about 1/2 the cost of a SS strip sander that I also would like. Ah, decisions, decisions... does it never end? Apparently when it comes to wanting toys it doesn't.
Have fun.
John

I have a large 2 HP dust collector that cost much more then the list price of the Shopsmith unit and it does a great job for the Shopsmith lathe (with 6" pipe) and my planner with 4" pipe. For collection off my Shopsmith Tablesaw and bandsaw with 2.5" ports I don't get the airflow I want and I usually us my Sears vacuum which is not designed as a dust collection and clogs quickly. The Shopsmith collector seems to me to be more of a vacuum on steriods and seems better designed to work with 2.5" hose.
Maybe someone here could explain the difference between a vacuum and a dust collector.
This is my third large dust collector and none of them worked well with 2 1/2" hose so I don't think it is a problem with the collectors.
charlese
As I understand it, a vacuum cleaner (shop vac) has a large static pull, but not necessarily a large quantity of air movement (CFM - cubic feet / minute). A vacuum usually has the filter located between the fan and the suction hose while a dust collector has the filter after the fan. Don't know how the "Dyson" works. Looks to me, as a series of cyclones to settle the dust prior to the filtering.
There is a discussion of dust collectors somewhere in the SS web site. I think it is listed withe the promo for the 3300.
