dust extracting work bench

[underfoot]

I'm thinking of making a work bench/station with a built in dust extractor..
I have a high flow exhaust fan in a wall in my studio and intend to build the bench over it with some sort of wire screen insert in the bench top ......make sense
(it's mainly for dusty dremel work).....has anyone made something similar or seen anything like one?

Like a downdraft table? Seen plenty but haven't made one.

Sounds like a brilliant idea. I'd love to see some photos of it when you get it done. I'm getting tired of vacuuming myself off after a session with the Archer...

If you're building a down draft table, the key is being able to block off most of that portion of the table not covered by the what you're working on

What sort of flow rate and at what sort of back pressure is the fan?

Just because one can see dust and chips on a bench does not mean that is where the invisible dangerous dust is. In the case of a dremel a downdraft table will capture very little fine dust because the downward air flow from a fan will not be fast enough. High speed tool tools spray fine dangerous dust all over the shed and in that case it might be more effective to leave the exhaust fan in the wall with out any restriction and just let it vent bulk shed air to the outside from there.

yesterday I didn't even know they had a name

I've got no idea Bob, it's an old axial air con ducting fan about 350mm dia..and it really moves some air
I know that when it's on you can feel the breeze through much of the shed. and the spiders in all the corners hang on a little tighter
thanks for the info folks ...I'll post some pics as it happens

The workstation is for D1 so I had her make it from scratch.
..cleared a space in front of the fan (haven't seen that wall for a while)
..a simple pine frame to support an old oregon benchtop..
... a chute from gap in bench to fan..
..and a screen so dremel bits don't get sucked out

[underfoot]

I was allowed to make a removable work support..
while she sealed all the air gaps,
and took it for a test run..
WOW ...It's like a (dust) black hole....

That sucks! Looks great

[Claw Hama]

Looks great. I can see I'll need a bigger fan though, one that will cover a dining table You two are becomming a force to be reconed with, D1 seems to have settled in, what a team

D1's lungs and well being are obviously more highly valued than the those of the missus while hanging working in the garden and out the washing.

Good job UF. That looks like it would be very effective.

Thanks for that Undie. The step by step is extremely useful. It's exactly what I need. Now all I have to do is find a wall that's uncluttered both inside and outside.

A great idea. Tools like grinders that evaporate wood need great extraction. Good job.
