I thought I would post another Thien separator but this one is using a 12 gallon shop-vac on a DW735 planer and working great. I have a basement shop without a DC so this is wonderful, I can now plane boards and don’t have to leave the shop until the dust settles. I have also tried it without the shop-vac and it still separates the chips so I could just run the exhaust outside. After planing a board down to 1/2” just a few chips in the shop-vac.

Timbo, great job but I have questions:
1. Where did you buy the fittings / hose ?
2. How does the Shop Vac work with the 4”hose?
3. How did you seal the lid to can?
4. How does the baffle attach to the lid?
5. Have you hooked it up to other machines like your tablesaw?

Thanks,
CB

Thanks Bob and Jim.

Bob;
1. Where did you buy the fittings / hose ? Local hardware store that also sells woodworking tools, they are DC fittings.

2. How does the Shop Vac work with the 4”hose? The 4” hose does not seem to make any difference.

3. How did you seal the lid to can? I haven’t sealed it, I do not have the clamp for it but it has a tight seal as it is, and I just put a heavy weight on top of the lid. I need to figure something out for that.

4. How does the baffle attach to the lid? The three 1 1/4” dowels, drywall screws through the baffle in to the dowels and same for the lid.

5. Have you hooked it up to other machines like your tablesaw? No, not yet, I just put it together today. I did use it with the shop-vac to clean up the shop and it worked great. I used a 4”-2” reducer on the suction side of the separator and attached the shop-vac hose.

Hey Timbo, it looks good and seems to work really well. I’m not familiar with the principal of how these work. Is the purpose of the separator baffle to block the larger particles from from continuing into the shop vac? If that’s correct, then I assume that the baffle has enough room around it’s edge to allow the vacuum to void the air in the separator but not enough room to allow the larger particles through.

I have basically a trash can with motors in it as my shop vac. First a large dust bag and then the motors which go on top have individual paper disposable filters and small cotton bags around each one. It’s not shop made. I am just wondering what advantages I might have by adding a separator. I sure would appreciate your comments on this.

Hey Mike,
To answer you question, yes. I think the elbow inlet directs the particles around the inside edge of the drum, the baffle is tight against the inside of the drum 1/3 of the way the other 2/3 is has a 1.5” gap and the particles fall to the bottom. the advantage of this separator is to keep most of the particles from making there way to the DC filter or in my case the shop-vac filter. Check out http://www.cgallery.com/jpthien/cy.htm there is a forum there with tons of info, also several LJ’s have built them. dbhost here on LJ has made a couple and also posted info at the thien forum.

Timbo, I like to use stretch wrap to get a seal. It’s cheap and easy to remove and air tight. Just wrap it around a few times. This might work for your setup. The stuff used in shipping and packaging.

I noticed that your separator disk isn’t notched like it shows on the Thein site, or am I looking at it wrong?

OOPS! I see it now, sorry.

One of these is on my list. I have my Delta DC tubed around the shop, but when I start making big time sawdust, I don’t want to fill up the plastic bag. I think I might be able to fit it right along side the DC plastic bag on its rolling stand, using a smaller separator than yours. These are pretty simple projects with a lot of value it seems.

Nice. I kind of wish my Thien was based on a fiber barrel. The plastic barrel is kind of heavy…

You should be able to use a cardboard barrel.

They are plenty strong. My old Sears Sop Vacuum was cardboard.

Tim’s Tip for Thien baffle barrels:

Go to HD/Lowes in the back where the trucks are unloaded, they usually have a big cardboard drum of floor sweep, they throw those away so ask them if they will save it for you. The local Lowes just wrote my name on it and called me when it was empty…..FREE!
