Default How much power do you think I need to make one of these?

I've been lurking over the internet to gather some info about the construction of (what I think would be best) a table saw hood for fine particle dust collection, more precisely, MDF particles.

So, I came across a lot of homemade "hoods" that would be great for this, for example:



Now, my question is regarding how much powerful would the turbine need to be for that to suck the most of the fine dust particles, instead of them becoming airborne dust really quick.

I've been reading it, but there is so much information and some knowledge is required to understand what would I need.. honestly I'd rather skip to have to think it for myself and use someone else experience in the matter.

It would take me months to gather enough information and to reach to a valid conclusion of what's best in my particular scenario..

The main and almost only thing I need DC for is my TS. I use the router very little and the mitter saw (I bought one a week ago, love it) is only used to make a few cuts.


Available here?, nothing really, but I can get one of these:



To use in the system I build.

Will you be adding dust collection below the saw blade also...? Or only above the table...?

What is the size of the duct and how long is it in the example you show...?

Is the example what you are going to build...? or is it example only...?

Will you be running a 4" line from the DC to the machine...?

Are you using a zero clearance insert...?

Have you looked at the specs of the "Shark Guard"...? or Excalibur...?

Do a quick search "building the overarm blade guard and dust collector pdf"

Try this PDF http://www.woodcentral.com/bparticles/blade_guard.pdf

Good literature, Stick...

Just browsed through the PDF's you suggested...lots of good info...

Very useful to me as I need to add DC to the Darra James in the cabinet under the blade...I'll be reading them more carefully tomorrow at work instead of sleeping :-)

I especially liked the Ducting PDF that talks about CFM's required and sizes of hoses for chips...

Thanks...Nick

I don't have an overarm but just setting the 4" hose of my Delta 650 cfm dc about 6- 8" from the blade captures most everything but a few of the larger pieces. With a shroud I'm confident it would be more than adequate for your purposes. Hope that helps.
