Project w/ Pics Ridgid oscillating spindle sander dust collection

[Martin Roper]

It almost invariably takes me two times to get what I want to accomplish in my shop done right. I'm on my second workbench. I needed two cracks at making a dust collection boom, two tries at a dust shroud for my miter saw, and I had to realign and repaint my slat wall. This time it was the Ridgid OSS.

Try #1:

I saw a YT video about a 3D-printed shroud that I figured I could duplicate in wood and PVC pipe. This is what I came up with:

It's not pretty, but didn't perform that bad, actually. Using a dust extractor, it collected the vast majority of the dust. Unfortunately the super-fine dust that survived the first bend and the suction eventually got thrown off the narrow end and accumulated on everything to the right of the sander. It was clear both ends needed to be covered.

Try #2:

I bought a 4" dust collection port and threw together some scraps. There's some OSB, MDF, 1/2-inch ply, 3/8ths ply, and oak in there held together with glue and brads. I used the scrappiest scrap I had because this was supposed to be the prototype.

I'm very happy with the result. I get a little dust right in front, but it works far better than I expected. A dust collector is better than a dust extractor in this application.

My next step is to make some kind of flip stop to attach to the left side.

Very nice design. Thanks for sharing.

Nice work. I have that same OSS. How is the dust collector attached to the sander?

I use Rockler's Dust-Right quick connect system. It attaches to the fitting attached to the plastic duct.

I have those fittings on my TS, jointer/planer, router table, and OSS. My shop is super small so my DC is only 5-6' from all of those.

Very cool
I have the same sander.
Did it stay in place while you sanded?

Yes. I have one star knob in the stock location, but it could probably use another one on the other side. I'll need to drill and tap a hole for that.

Nicely done! I also have that innate ability to replicate attempts. I also use the scrappiest scraps available since well because. Funny how sometimes the scrappiest prototype turns out perfectly fine except it is made from well scrap and looks like it lol So then you have the issue do I redo with presentable materials or accept the functionality over aesthetics dilemma. I will be making something akin for mine. My eyes and especially my lungs also thank you!

I was wondering more about how the adapter was attached to the tool.

I was wondering more about how the adapter was attached to the tool.

The sander came with a stop that attaches to the top like this:

I built a mount into the left side of the shroud and used the stock star knob to hold it down. There are also two tabs that align it to the back.

Surprisingly, that holds it in place pretty well. I'll probably drill and tap an identical hole on the other side to make it even more secure.

Awesome, thanks. I'm not sure if I still have that accessory, but can use the threaded hole.

Here is the YT video:

I don't get nearly as much dust as that with the big shroud. He's getting a lot of dust in front because the belt mechanism is between the suction and the dust. The overhead location of my inlet creates suction all around the belt.

My small shroud was better at capturing dust to the left of the belt, but expelled more dust to the right, probably due to the inlet hole location. The front of my shroud also extends past the plane of the belt so dust has no place else to go but straight into the area of greatest vacuum.

Nice. I'll start looking for 3D print files or draw something up myself.

I found this photo that illustrates the exact problem I was having with Shroud 1.0.

Note that the dust which gets carried along the back of the belt hits the end and centrifugal force deposits it on the right side. I suspect this is going to be a common problem in "single-ended" designs.

The stock dust port is designed to draw air from under the belt. I think the gap between the table and the belt is too narrow to get sufficient airflow to draw dust downward into it. This fellow tried combining the single-end method and the stock port. I wonder what kind of results he got.

I tried the stock port and it was only a marginal improvement over no dust collection.

Here's one that looks like mine but it's not clear where the hose is connected. This was the only photo and there was no accompanying text:
