Splitting a CT 22 for Nearly Dustless Extraction on a SawStop

I don't have a saw stop yet but I've been thinking about the best way to set it up when I get one to get the best dust collection.
If I had to guess, I'd think the best results would be from using a large dust collector on the 4 inch port below the table with 4 inch piping and then use a festool or shopvac on the blade guard where the piping is choked down.
A shop vac doesn't work it's best when aligned with a large 4 inch port and a large dust collector with a 4 inch or larger intake doesn't work well when choked down.
And if I did have the festool vac on the above table port with the below table hooked to the cyclone dust collector, then I'd have to figure out the best way to trigger the festool vac automatically since it is 110 and the saw stop and dust collector are 220.
Oneida makes a new 3hp dust collector that is supposed to adjust the impeller speed to optimize it's suction for either scenario, but even so, if it were hooked to both a large volume low velocity port and a high velocity low volume port at the same time, even it would probably be a compromise.

My PCS 1.75 HP is 110.
David,
I thought your saw was 110. My table saw now is 220 and 3hp and when I move up to the saw stop I'll probably stay with 220. Besides, I'm not sure if that's a lot to ask of the CT if you are doing a lot of heavy cutting under heavy load. It may be fine, just sayin.
I'm sure you set up is working for dust collection, to make it work better I think you'd have to match the dust extractor to the tool inlet. Using one system is a comprise and suction would be reduced a little more with the Y.
How small is the ID of dust collection inlet on the saw stop blade guard? I never measured one, but it looks to me to be about 1 1/4 to 1 1/2.

Nice! I was admiring the DC on the sawstop last trip into woodcraft. The integration to the splitter and the ease of putting it on and taking it off is nice. I also noticed your GRR-Ripper. I have a couple of those and they have been some of the best investments I've made. Walking long pieces through the fence is a piece of cake with two of em. Again nice set up. I hope to have a sawstop someday.

Thursday at Eagle Tools in Los Angeles I noticed their demo SawStop Industrial cabinet saw had the overarm dust collection system. That connects to a Tee off the main 4" dust collection port. I have one of those on order with a 48v 3 phase 7.5 hp motor. As fond as I am of my CT22s, I will be connecting the Saw Stop to my main dust collection system.
Wow, I would think such a table saw would fill Ct22 or CT33 bags very fast.
For my Kapex I use a 50mm hose to connect it to a CT22 when I take that Kapex to sites. The Kapex I normally use in my shop is connected to the main dust collection system. It also has a DC hood behind it connected to the main DC system.

Yes, they might. I don't do a ton of TS work, though. More importantly, I don't have a real 4" dust collection system. It just won't work in the space I have.
I figured if nothing else, people might like to know about that optional dust collection guard. They can always use the CT?? on just that, and not have to purchase the expensive extra tubing/piping.
thanks for the info david.
i appreciate the great photos and descriptions.
the other poster wanted to know if the ct-22 bags fill up fast.
well i can tell you from my experience onsite using the festool cms ts-75 tablesaw for approx 4-5 hours non stop with the ct-22 and the long life filter bag.
i emptied the bag 5 times. so i reckon that translates to emptying the bag every hour for non stop table saw use.
as i am working onsite it is impossible to have the ultimate dust control 4inch setup with cyclone etc, etc.
and because dust is a major problem when doing finishing work, (painters despise us carpenters).
the ct-22 is without question the best setup you could possibly ask for.
it collects 90 - 95 percent of the dust, emptying the long life filter bag 5 times is much easier than cleaning up 5 hours worth of sawdust!

G'Day Justmcf and Hi David!
Last December I spent a delightful couple of days on the Gold Coast on my way back to Los Angeles after filming a documentary about numbats in WA south of Perth. Had I but known I would have rung you up!
Seriously David, it was seeing the CT collectors in action in 2006 that brought me back into woodworking. I had no space for a conventional shop once I moved to a condo. I did have a spare bedroom with excellent north light. There being no space for a table saw, I got the Festool guide rail religion! Big Time. Even without a ts my TS55 EQ filled its share of CT22 bags. I selected the CT22 because it would fit on the back seat of my Grand Am and the CT33 would not!
I fully understand using a CT instead of installing a traditional DC system, especially when using your tools once in a while and on site.
I do have 2 CT22 currently, one with an official boom arm and one that often works with a boom arm I built. That is the CT22 which we also use on-sites. In the shop when I am using most Festools I find they run best with the CT22 instead of the installed DC system. The exception being the Kapex which works fine with the big DC.
Besides the Industrial SawStop I have on order, I am buying a SawStop portable contractor's model. For use in the field, David, I will use your suggestion and hook it to a CT22. However, since we now have a truck, as soon as they are available I will buy a CT36. That self-cleaning bag feature is marvelous. In many ways I feel the engineering of SawStop is similar to Festool principles in that dust collection is there from the beginning.
