Ghidrah It also depends on the type of cut being made and wood species, the more material that is removed during a pass the more material falls into the cabinet. I have a 6hp Craftsman shop vac attached to my RT.

Practical experience;
Empty vac tank and clean filter. I duct taped the cabinet line using the fence line only (producing higher vacuum at the fence). Light slow cuts and -0- debris, the heavier and faster the cuts the more the debris in the cabinet even though the router exhausts up. I've also seen chips stuck to the router intake.

Both lines operating and I don't have the vented door in place I get debris of varying sizes on the cabinet floor, no debris stuck to the intake.

Door closed, still get debris but a fraction of the amount and no material on the router intake.

I believe if I invested money in many -0- insert plates and the time needed installing and removing them for each bit used the fence line would be sufficient.

Material blocking the intake is a bad thing, but unless it's wedged into the fins, it drops off when the router stops. what's more damaging is the fines that get sucked up into the router and cake. I lost my 1st PC 694 free hand routing composite decking, the router wasn't inverted but fines still sucked up into it built up and melted in the router.

Mike Dave, you need the same opening area as the exhaust. 4 2" holes plus the open area around the bit should be good for a 4" collection hose.

a-cut-above Thank you for the feedback. I just finished making my router table into the extension of my table saw and only have a DC port in the fence directly behind and above the bit. I was hoping to get lucky and have that get all the chips. It doesn't work with the table saw (DC above and below needed) so I should have figured that out. Once I make the under-table box for the router (it won't be dignified enough to call it a "cabinet") with a DC port, how do I know how much air to let in to i) create the right flow for chip collection and ii) to ventilate the motor? Is a pegboard covered "window" on one side too much, three slits in front too little, etc.?

Mike In the real world saw dust will drop to the bottom of the cabinet. This is why all the pro built systems have dust collection at the bottom. The fan in your router will keep most of the dust out of the motor but it will not push it above the table top. Be sure you have enough make up air to let the dust collector pull the dust away. Think like an engine in a car; the more fuel that goes in, the more exhaust goes out. Deny either side of this and the balance is thrown off and your performance drops like a rock. As long as your air supply matches the vacuum you will get great dust collection and your router will stay cool.

I suppose I would put the DC port near the top of the box (bottom of the router) to avoid the overheating problem. What has your experience been?

Hi Dave,

Depending on the job at hand, I get quite a lot in the cabinet. I have the OP vac-u plates so, I can hook up a vac or DC unit at either underneath or, at my fence. Either way, you can't get 100% of the dust and chips.

jmg1017 My experience has been that most of the dust/shavings make it to the floor. That's why i'm looking into a new setup. Either a cabinet style table or a metal table from Woodpeckers that includes a dust collection box.

levon hey Ken,

you should have been a philosopher,lol! but i agree with you! a shop is different things to different people. to me its where i use mostly woodworking tools. my woodworking tools make a mess. im ok with that. if my shop were in a basement or other part of my home, where my wife would raise hell about any speck of dust i would probably think differently.
in that case, i too would probably think it would need to look like an OR. i know that using a dedicated dc and air filtration would help, but there are times i do jobs that cant use some type of vacuum system and spit dust all on the floor and other stuff. but thats ok in my shop!

Hamlin A dust proof shop = using your tools outside.
