Has anyone done a custom fume extractor arm?

[Melissa]

I want something fairly large and light that I can mount centrally in my work area and maneuver easily over whatever I am working on. I have a number of different openings I have made out of fiberglass to use on the end of the arm depending on project / need.

Here is a prop and mold

Now I just need to find a big arm that I can attach ductwork to. Ideally, I want to find something cheap that I can just buy and repurpose instead of having to do a bunch of welding and designing. Anyone seen anybody do this or have any thoughts?

like this but not $1,500 bucks.

My thought is...huh?

You would rather pay for one straight up? Is there a cheap option out there besides grainger that is good quality? I want it to be usable over a large area.

I bought an arm made by Nederman in the link.

I got it through an auction house for very cheap.
EDIT; this is the one I got, under $100;

I made one from one of those swing arm light frames the ones with springs and mounted it on a tripod. the suction fan was a dust collector motor vented out the wall.

The arm was similar to this

I was thinking about something with a ballast at the end, I have a desk lamp that uses a ballast and it can be re-positioned fairly well and stay put. But just to put things in perspective, I'd want it to be usable in a roughly 20' x 20' area. The more coverage I can get the better.

Thanks for the links! What an awesome find. If I could pay 100 for that today it'd be done. Where do you find out about these auctions?

I would use PVC or dryer hose, or furnace ducting for the tubing. Not sure what diameter you want to use but rubber plumbing couplers with worm drive clamps could do the trick for the elbows. Two elbows connected would give you a lot of flexibility.

Or are you asking about the support arms? For those electrical pipe conduit with two sizes might work. Smaller diameter in the larger. Drill holes through both to run bolts through like how engine lift\cherry pickers are.

Alternatively google image search homemade fume extractor and you might find some good photos to see what others have done.

Is this only for fumes or for actual particulates? If you're trying to move solids, you really need to make sure your transport velocity is high enough for your particular solid. And obviously have a fan/motor that's correct for that application.

I got lucky with a local auction house that I frequent that deals with industrial/commercial. Check out some online government auction sites, you might get lucky too.

Look at woodworking dust collection fittings for ideas...same concept as your fume extractor. Here's one option:

This is getting very close to what I want. Thank you for sharing! I will probably end up doing a ceiling mount version of this setup, and I will share pictures with all of you so I can hear what I did wrong

I want this to be a catch-all particulate / fume extractor so I will definitely be powering it with an adequate blower.
Cheers.
