What do you use for dust and fume extraction at your sanding and finishing workbench? I purchased an inexpensice fume hood fan and that would not work well unless it was inside an enclsore. I returned that and bought a Penn State dust collector head and that may be overkill. Perhaps a squirell cage fan would work? Just looking for ideas on the "fan" and any ideas on how you implemented the bench used for sanding and finishing.
Dust and Fume Extraction

For me, dust and fume extraction are two different problems.
I use a Ridgid shop vac connected to a Dust Deputy dust collector. A longer hose goes from the Dust Deputy to my spindle where I mounted a custom connector. The Dust Deputy does a great job of capturing dust and wood chips, dropping them into a 5-gallon bucket. The remaing air is pulled into the Shop Vac where I installed a HEPA filter to get the fines.
Fume extraction is handled by a separate exhaust fan that goes directly outside through a wall.

I agree with Gary. Fumes and dust need different solutions. For dust, a dust extractor or downdraft type system connected to a shop vac works well.
For fumes from epoxy, and especially clear coat, you need a different system all together. A fume hood, spray cabinet or a separate room is needed. You need a way to suck the fumes out and vent it out from the area you're working in, so you need and explosion safe fan with enough power. A 3 stage filter that delivers breathable air, so you can use a fresh air mask while spraying or working with chemicals is key. You can get by with a 3M full face mask with the right filters if this is something you do very seldom.

I use this in a downdraft box under my spray station and toss the hose out of the shop door. Works pretty good

I agree with Kim and Gary, it's two different processes. You don't necessarily want sanding dust where you're doing your finishing. I got tired of wearing a mask while sanding so I took a couple hours and some scrap and built this downdraft box. It has dovetail rails on the bottom so it just slides over the ways. I hook it up to my dust collector while sanding and problem solved. It also gives some protection to the lathe bed. I'm still working on perfecting my finish area. I'll probably go with something similar to what cuemaker supply mentioned above, but I'd feel more comfortable with an explosion proof fan.
Thank all of you for the information. @kgoods, do you have multiple ports below the v-opening or just one on the side? I am not sure what I am seeing in the groove in the middle and at one end. If only a single port, I would think it would have good flow near the port but very poor flow as you move away form the port.
I like this. Does it catch all the dust?
That was one of my concerns. But I figured I could just narrow the gap in the slot near the exhaust port and leave it wider at the ends to "tune" it. But turns out it's not necessary in my case with my dust collector (which isn't state of the art by any means). If you're running a shop-vac or similar you may want to adjust the slot width to tune the velocity.
What I think you're seeing is two supports to keep the walls from sagging. They are only about 1" long so the majority of the internal area is completely open. Probably overkill but that's just the way I am.
Hopefully you can see in this picture that there is some dust buildup at the ends and the center is perfectly clear of any dust. But keep in mind the dust is in the box which means it's not in the air.
Here's another shot of the chuck end showing the dust stuck in the box. This was after a long sanding session on a refinish. I disturbed the dust to be better able to see it.
It's easy to clean it out by running a brush over it while the collector is running.
Here's a shot of the dovetails. So handy, I don't have to clamp it to the bed at all. You might notice the overhang at the chuck end, that's there so I can butt it up to the headstock and it easily clears the chuck. It positions the cue perfectly over the dust box opening.
My only mistake was to add the holddown clamps to the hose input. Turns out I cut the hole so tight that the hose taper fits well enough that I don't need the clamps. I'll be removing them to allow more clearance behind.
I think the trick is to keep the clearance between the cue and the fixture minimal. I can just get my fingers/hand around the cue between the cue and the box.
Hope this gives you some ideas.

Thanks Chris! Yes, I can't detect any fines in the air nor on the napkin when I blow my nose!
Been meaning to post this for a while....tinkering around a little this evening...
For a hobbyist/work on your own cues/things for buddies....this works pretty well.
Just have a rockler/woodcraft hood and use a portable dust collector -or- HF fan i put a couple 8" to 4" boots on for fumes....

I'm not a cuemaker but thought I might make a suggestion. I built something when I was doing some remodeling to collect the drywall sanding dust from the OSB flooring before installing the Carpet. Don't know how well it would work for rough turning but fine sanding it would probably work good. It's just a 5 gallon bucket with water between the vac and whatever you are using to collect the dust. When you are done sanding you could just water the flower beds.
