Is this the Ultimate Router Table? dust collection

As far as I am concerned dust collection should not only get rid of the dust, but can and should help keep the router cool, and if designed right can help control the little of the noise.

I have 4 paths for air as it travel through the router table on it’s way to the dust collector. Starting at the bottom, air travels across the bottom or under the router to an opening as shown in photo 2.

In the middle, air travels through baffels as shown in photos 4 and 5, these are in a 4 inch thick cover that covers the front of the of the area where the router is. The idea is that this will cut down a little on the sound getting out the front of the router table and then to the operator. Air travel across the router motor hopefully keeping in cool and drawing dust away from it. In photo 1 you will notice a vertical slot about 4 inches high and 1 1/2 inches wide, this is where this air is drawn to.

Between the router and the top is a channel where air travels to clear chip away from the top of the router, this can be shown in part in photo 3 This is talked about in “Is this the Ultimate Router Table? router lift”.

And then there is dust collection at the fence, which sorry to say I have not built yet.

How many cfm are you planning to use?

I politely have to disagree. Looks like it was fun to make but there are so many spots that constrict air flow, places where dust will stick ……….I dont get it ? I am a personal believer in the theory “KISS”.

@Moron, air flow so far seems to be very good. I guess time will tell. After I get the fence built and do some routing I will post a report on how things work. Could you please point out the spots that constrict air flow so I can pay addional attention to them?

@ Doc…, right now I am using a jet 1100 cfm collector, however if and when I get things straight with the city I will be able to have 220 to the shop and have a 5 hp blower/cyclone system from clear view, not sure what the cfm is but there is plenty of sucking power. At that time I will be selling the jet.

any 90’ angle constricts flow, even clean sweeps reduce flow, as does any partition. Even the surface of that hairy fir plywood will reduce air flow.

Sometimes I build things because I can : )) so as they say “Nothing ventured, nothing gained” the experience will be worth the journey.

Most often I have to build a router table in the heat of the battle, no time to think about, just make a safe environment for the router to act as a shaper and then throw it out so my thinking at this point in my life is probably much different then yours : ) so I invest my time into buying the best bang for my buck in terms of dust collection. I personally could not improve upon it so this is just my observation of what “I” see others do.

Keep it simple. Don’t enclose the router, ensure its easy to access, has plenty of air around it, make it accessible so that a physically disabled person could use it, an older person. Again, just my observation and belief that I would rather spend my time “woodworking” and not busting my knuckles and fighting with over complicated foresight : ))

As for the actual collection of the dust. Lee Valley sells a magnetic dust port that can be safely put nearest to the collet, under the table connected via a hose to the dust system. You can add more, move it to a better position pending the tool bit in the router, and it would be simple to make your own. They mimic what Festool does with their system in that they try and minimize the area surrounding the tool bit, encapsulate it so to speak. One above the router bit, and one below. This can also be done on the cheap, with a few scraps.

As for noise reduction. Some routers are the worst screamers ever. Like a horror movie and if turned on in suburbia, makes for frosty relations with neighbours. ……so I see the logic in trying to shut it up : )). I realize that budget constrictions are a big concern to a lot of people but as a rule, the more you spend on the router, the less it tends to scream, and if you buy a really nice one, it almost sounds like a kitten with a beautiful ….”Purrrrrrr”

Like I said, ………we climb mountains because we can

I should add 1 more thought.

I am delighted to see people busy with their hands, their mind, to spend time doing what they love. I often walk and look at gardens, some don’t make sense to me so I remind myself that any garden made with good intentions is better then no garden. So spending time actually doing something creative no matter who defines it, instead of being glued to the TV, …………….is “time” well spent.

Cheers

WOW! If it works good, great! If it works awsome, I’m still not going to have that on my router table lol

Alot of time spent there.

1200 cfm is adequate. Moron’s comments about corner collection was also going through my mind. Seems to me if there is an edge or a corner their will be buildup. Your new vaccum should work better at keeping dust out of corners. if you have a hard reflective surface it will actually increase the noise level. high density foam board could help. it is often used in insulating walls for sound in buildings?

I’ve got the delta 1200 cfm. Bought it before I researched air flow. Just have to keep runs short, and blast gates shut. LOL!

New update: The dust collection on this works great, no build up of dust of chips under or around the router and the router stay very clean and dust free. Air flow across the top of the router is good and keeps any air from the router motor from blowing up through the table opening or around the bit in use. The noise attinuation is fairly good, but I still use ear protection.
