Hi Paul,

Your description of leaving the DC3300 running when not hooked up to a tool is exactly how I was told to keep the air clean.

Is this what you are looking for?

Dusty, this link does not work for me. Is there some text on the page I can use to search with to find if it has moved?

I just picked up a used DC3300 and then ran across Bill Pentz's website. Bill's website got me thinking more about dealing with the hazards of very fine dust particles. I was trying to figure out what to do regarding getting adequate filtering for the DC3300 when I ran across this thread.

Reading Nick's response here, it sounds like if I add the 42" filter bag, I should be ok. In the dust collection Sawdust session, Nick says the 42" bags are made by American Fabric which are also mentioned on Bill's site.

As always, thanks to Nick for his excellent explanations and to all for the great technical conversation. This forum makes getting started (and apparently continuing) with the Shopsmith so much nicer than struggling through it on my own.

rick, I must apologize. I can not find the referenced post myself and I am embarrassed to say I don't recall what was there.

With a little luck, when charlese reads this he'll recall.

Shopsmith has had some problems with a couple of the archived Sawdust Sessions and I believe that was the reference. Sawdust Session 9 which was on Dust Collection Systems.

Hi Rick! Dusty has come up with the posts that work! I think the earlier link used to work, but does not any longer.

If you are looking for the wooden manifold - use the second link on Dusty's above post and scroll to the bottom of the page.

The 42" bag as mentioned by Jim is the best. Air flow - Air flow - et al.!
Good Luck!

I think Nick mentioned Bill's dust collection site. Here it is:

When I started reading the Medical Risks section, I almost decided to take up needlepoint as just looking at a board it appeared as if you would breath in something.

Good site with more information than you'd ever need.

I ended up buying a Grizzly dust collector as it had better cfm and a better micron filter which is easy to clean plus the machine runs pretty quiet. Also I could drive up to Bellingham, WA and pick it up and not pay shipping. I also could have picked up one of their 10 foot table saws, but decided to stick with my 510/520.

SS does offer, as an option, a very good hood. I would have bought the DC3300 with the "best" hood if they offered it that way. I find it hard to justify "throwing away" a brand-new hood, so I am using the small hood that it came with:( . If something goes wrong with it, I will definitely replace it with the largest hood.

a1gutterman,

I have had my dust collector for 17 years. About three months ago I put on a new, larger hood.

I washed the old one, inspected it, folded it and put it in an airated plastic bag and stored it away. Someday, my grandson will drag it out and may even use it (or sell it).

Incidently, I work in an open air shop (garage with large double door) and I can not say I recognize any improvement as a result of the larger hood.

So, what you are telling me is 1) The small one won't wear out, and if I wait, it will never get replaced, and 2) I may not notice the difference anyhow. Just how is a guy supposed to justify these purchases to SWMBO with testimonial like that?:D

I find it confusing concerning the particle size with the different size hoods. The description of the replacement hoods on the web catalog says "The Filter Hood of a Dust Collector cleans the air that's returned to the environment once the dust is removed. As it does this, a "cake" of dust forms on the inside of the Hood. The thicker the cake, the smaller the dust particles it will hold captive inside."

Therefore, it seems a small hood filters just as well as a large hood except that you would have to shake out a small hood much more often than a larger hood - just to maintain air flow. After you shake it out, smaller particles would not be filtered until the cake of dust builds up again.

However, Nick says that the 42" hood is made of a different material than the other hoods. A 1 micron capable material. Then why doesn't the catalog say this? I can't see any reason to upgrade to a larger hood unless you need to constantly clean the hood to maintain air flow. See link
http://www.shopsmith.com/ownersite/cata ... rhoods.htm

This catalog page also has a link to the 42" hood pdf file. This file says "Because the dust-cake on this filter hood also filters fine dust particles, this filter hood may never need to be cleaned as described in your Dust Collector Owners Manual. If you choose to launder this filter, be advised it will not filter the finest of particles until a dust-cake builds up on the inside."

It seems to me that the catalog says that the dust cake on the inside of the bag determines particle size filtered - not the bag material. But Nick says the 42" bag is by a different manufacture and that is where the 1 micron capability comes from.

Am I missing something?
