Having removed most of the dust with my previous under the table jig
I decided it was time for the more important feature of dust removal. Over the top dust removal.

I wanted to make the whole arm thing out of aluminum since I dislike hard on the eyes jigs and projects no matter how useful. But after checking on aluminum prices, I decided my eyes could bear the brunt of hideousness and also the arm is 105 inches long and aluminum comes in 84 inches mostly.
So’ onward with leftover wood scraps.
The fun part was making the plexi glass dust housing. It’s airtight and EZ on the eyes and that’s what matters. It’s has the 2.5 inch hose connection interface. And It’s 3/8 thick as you can see from the pics. The weld or glue was hard to work with but considering the difficulty level, very little mess.
So, I guess I have to live with the wood version. ;-(

Very nice. I have been wanting to build one for a while now. How stable is the wooden support stretching that far?

If it works, it appears to me to be a winner! Anywhere you are doing multiple size cuts, it appears this would work well and easily. If we’re doing a multitude of different thicknesses, how easily does it adjust? I like the looks of it and the ingenuity you invested. Great project! Thanks for sharing. I may have to give this a try.

It’s extremely stable. If I were to grab the arm and pull on it of course it would break but it will not break from the weight. I could have made it somewhat stronger by using oak but didn’t want to spend any money and had all this junk pine lumber around.
My only reason for wanting to build it out of aluminum is aesthetic.
The design I came up with has the advantage of being portable. I’m not tied down to moving the arm stand as other designs separately or being stuck under the ceiling type dust hanger. This way I can move the table saw and the arm goes with it. And it is EZ to adjust the height just loosen the knobs and move the dust housing up or down and then tighten down.

Nice guard and dust-collector in one!
-I am not questioning your work, but why 3/8” for the dust housing? Would a thinner material have worked? I am thinking on the strain on the horizontal beam, an looking for less mass. Maybe like the “pine lumber”, it cost nothing.
Nice over-all dust set up, I need the same on my saw that has nothing but a chute to the side

I always use 3/8 for jigs that I make for router and saws so that’s just what I had on hand but I decided that it would work best since it gives more surface area for weld.
For dust housing i wouldn’t use anything less than 1/4.

Don’t use glue on plexi glass use special solvent. weld-on ips 16 in this case.

very nice. I sort of like the wood look of it – much more homey and earthy (in a good way) than those iron posts.

That’s for me. Great! I’ve been trying to sort something for the top collection.
