Dust Collector ??

[quote="2bits"]I did watch this Sawdust sessions http://www.shopsmithacademy.com/SS_A...Collection.htm a couple of times and I am not sure how he connects the "octopus" to the DC.
I think I will first try using a couple of elbows from the 2 1/2 ports to a 2 1/2 tee, then use a reversed 4"to 2 1/2" reducer (increaser) and as short of a section of 4" as possible to the cyclone exhaust side. Then run a 4" "Y" off of the cyclone intake and reduce it down to 2 1/2" for most uses and try a short run of 4" for the times I use the planer.
It may not perform to optimal standards, but if it keeps the dust out of the air and in the can I will be happy.
This reminds me of a Fire Hydralics class I took some 20 odd years ago. Using the friction loss formulas it was concluded that the hose lays we used in wildland firefighting would not work. We spent days debating with the city guys that, while it may not provide the reccomended g.p.m. at the nozzle, we did get water up the mountain and the fires were put out.]

The DC3300 was designed for 2.5" hose.

On this page they indicate that a 4" kit is still an option:
"Exceptional Hook-Up Versatility - with three inlet ports, your DC3300 can serve up to three machines at once. Or, replace the 3-way inlet with our optional 4" inlet assembly and connect it to a permanent, hard-piped system to serve the whole shop."
http://www.shopsmith.com/ownersite/catalog/dustcollection.htm

On that same page I had to chuckle at their tiny little shop reference:
"The DC3300 will remove any lingering airborne particles (as small as 7 microns - only 1 micron with optional 42" Hood) from a 12" x 12" shops in about 10 minutes - while you're straightening up."

When you go to the dust collectors accessories page item "F" which appears to be the 4" adapter and elbow is "no longer available"

Ah! But the water was not 'suspended in the air flow!:D

Since I get the impression this will be a permanent setup, I would suggest removing the 3 port adapter and make a 4" one. All those turns cause static pressure drop.

Bigger than mine!:D

But then I seldom 'straighten up'.

When my shops was 13 X 18 feet I always left the DC3300 running for about 20 minutes with one and 1/2 dust chutes open and no hoses on either. The airborne dust was always gone by the time I turned it off. The new shop is 500 square feet and it takes both the DC3300 and a ceiling mounted Jet air filtration system to cleanse the air. Generally it takes nearly an hour. Today I spent most of the afternoon turning a maple bowl and then sanding it. An hour later the air was clean. Jim

144 square inches is a pretty small shop even for small shops.

I all most hate to post this but...

If the dust has to travel at 3500 ft/min so that is doesn't drop out of the air stream then it would seem that the general dust in your shop will be at a speed far less then that and the dust should be dropping out and landing on everything in site. So how then does all this get picked up with a open port on your vac or dc?

Sometime when you have a chance bring home one of those helium balloons and take it to your shop. Let it float around then try to suck it up with a hose from 12' away, 9', 6' even 3'... now try it with your open port... how close does it need to be???

Now put the hose in the outlet of the vac if it has one. Put the balloon 12 feet away and blow on it... Notice anything different? You bet you do.

Just saying if life is giving you dust get a balloon and play with that.

Yeah and a bitch to fit a Mark V into. I actually copied that from a prior quote, I suppose they meant 12' X 12'
