I’ve started a project to redesign the shop layout, and try to be mindful about it. While laying everything out, I came to thinking that the Grizzly 1023S (left tilt saw) has the dust port in the wrong place. The fence sits to the right of the saw blade, so I wanted to place that side of the saw up closer to the wall. But the 4” dust port exit is on the left of the saw, beneath the motor housing. To run dust collection, I either have to make two 90 degree bends around the saw or come straight out – a trip hazard.

Am I missing something? It seems like the new 10” saws, 1023RL have got dust port on the rear, so maybe that’s just a design goof they’ve fixed.

Has anyone repositioned a dust port on a cabinet saw, or added one? I’m probably going to do it, but if there’s any tips or warnings I should look out for :)

I have no first hand knowledge of that saw, but the internals will determine if you can relocate the port. For one thing, it may be connected to a hose that runs up to the blade inside the cabinet…mine is, and I’m kinda stuck with what the factory provided. If it doesn’t have that blade shroud, it may have a ramp that slopes to the left, and the port located at the bottom of it. You may have to try and move it to slope to the rear (or not) to put the port there. If the cabinet is open (none of this stuff) with just a flat floor then I’d say all you have to do is put a flange (and a hole) on the rear of the saw and seal up the existing one. You might want to consider adding a sloped piece if there isn’t any.

There is a slope, no shroud. Rather than bust out the existing slope I’ve considered just stacking one on top or adding a half slope (so it makes a V) and locating a port in the valley.

Better yet you can add a new dust port without removing the existing one. Add blast gates to them and you have a really convenient dust extraction feature.

Please keep us updated on this. I have the same issue with my Jet – forever tripping over the dust hose. Also, it seems that the orientation of the blade would favor most efficient extraction in the same plane. I’m pretty sure a 90ยบ would clog promptly and often.

I have a left tilt general international cabinet saw similar to the Grizzly. I’m thinking about adding a 5” port on the inside (cutters right side of the blade) for similar reason to avoid having two 90 degree elbows and a trip hazard to bring the DC hose back towards the wall. My saw has a large ramp built into it to push the dust toward the port on the cutters left side of the blade. Trying to decide if I should cut out the ramp or leave it and run the hose inside the cabinet down to the bottom of the ramp?
Anyone ever done something like this? Is it a waste of time and should I just run the hose around the corner? How much friction loss would I actually have from wrapping it around the corner?

So I got an email that someone had replied to a topic I was subscribed to. “Add a dust collection port”? That’s just the thing, I’ve been thinking about doing that… Imagine my surprise to find it’s a topic I started myself a year ago. A new job and a new baby and somehow I have not managed to complete this project, or really visit the shop, at all.

@CabinFever my rough plan was to fit a new plywood ramp on top of the old one to direct dust to the new port. I’d be hesitant to remove it in case its providing any support to the cabinet. Also that way if I ever wanted to revert I could just knock the new ramp out, plug the port and it would be just like it was before.

I couldn’t say how much loss you’re actually facing, I was always rubbish at doing those cfm calculations…

Have your say...
