Increase a tablesaw dust collection connection size on a saw with internal hood/hose

[Mike Heidrick]

Anyone increase a tablesaw dust collection connection size on a saw with an internal hose and shroud? I have an ICS sawstop and it has the internal shroud and outside 4" port. I am thinking of bolting on a 6" or 8" nordfab angle flange adapter with the existing port inside it and then cutting additional half moon or some holes around where the flange hole will be but not enough to ruin the flange.

Anyone have other great ideas?

That's exactly what I did. I went 6" for the flange and riser, then 8" trunk. If I had to do it over, I'd probably go 8" all the way to the saw. It doesn't remove all the dust, but keeps it at bay. I haven't cleaned the saw base out in a couple years. I cut a crescent moon shape below the existing hole right down to the bottom of the cabinet.

I'll need to do the same when I hook it all up. Additionally the cabinet will need extra air coming into it. I plan on cracking open either or both the motor cover or the smaller door on the opposite side of the saw until there is enough airflow. The safety switches will need to be held closed or bypassed. Once satisfied I'll either leave them propped open or cut a hole/holes equal in area to the "cracked" openings in the doors or cabinet.

I find this interesting and wonder about it. I have a Sawstop PCS and pull 670 cfm at 10.02" when connected to the 4" port. It does a very good job.

What kind of flow do people think is needed to do a good job of dust collection?

[Mike Heidrick]

Pcs have the flex inside too to the shroud?

Yes, they do.

In my experience good overhead extraction is at least as important, probably more, as airflow through the cabinet. So if you don't have a good overhead guard focus your energy there first IMO.
