Has anyone used flexform hose for overarm dust collection on the tablesaw?

After looking into overarm dust collection systems for the TS, I decided I would like dust collection without a blade guard. I saw a post on LJ where a guy accomplished this by hanging a hose from the ceiling, and supported it with a hinged metal apparatus.
That got me thinking – why not pipe in 4” pvc from the ceiling, and convert to flexform pipe 2 feet above the tablesaw? It would be easy to reposition the hose for thick or thin stock, and could be moved out of the way if needed.
I am using a Jet contractors saw and Jet 650 cfm d.c. Has anyone tried two 4” hoses simultaneously with a 1.5 hp dust collector like mine? Is it worthwhile, or should I make the overarm dust collection ppe 2-1/2”?
Thanks for any insight!

Genius. Why didn’t I think about that? I don’t like the blade guard for most of my cuts either. Since mine hangs off the splitter, it’s really annoying to me. Annoying things are dangerous. Until I figure a way to attach a blade guard on a boom that can lift away, this is a perfect solution to my dust collection at the blade.

Why could you not put a blade guard on the flexform hose? The stuff I have used is very stiff and a light plexi guard should not weigh it down.Might be a PITA to adjust though….....hmmmmm

I’ve been wondering the same thing for a while now. Except I was thinking about a different kind of hose – thanks for the post, albeit I’m 2years behind, haha.

I’m thinking that won’t catch as much dust as a larger basket, but that’s only a guess. Still worth trying, and it could be easily changed if the performance isn’t what you want. I’d be interested in your opinion of how it works.

Recently I built a new router table top and added an Incra router plate with their dust collecting inserts.

They have greatly improved the dust collection on my router table. I’m wondering if the same concept on a table saw insert would work. I’ve been thinking of making a sacrificial insert our if wood and giving it a try. Anyone done this?

Are you planning to move the saw or keep it in the same place?

I move my saw so I have the dc hose attached to the the blade
guard. I’m a blade guard user so I would use the guard anyway,
but the hose allows the saw to be moved to a position with more
outfeed room for large cuts.

A guy in Fine Woodworking came up with a ceiling mounted
guard with DC that was a sort of telescoping pair of long
plywood boxes.

My concern for having any hose hanging there without some
more rigid structure is that it would find a way to touch the
running blade sooner or later. I understand that the hose
you’re considering is pose-able, but if I were you I’d run something
rigid most of the way and use the flex hose just at the end.

Have your say...
