Planning my next router table and thinking about dust collection. My shop vac works great in my current router table, which is an open stand.
The next router table will have an enclosure for the router, and I want to add a DC hookup to the bottom of the enclosure to also pick up dust/chips that come through the bit opening. This made me think of one possible configuration to use both a shop vac and the DC: Connect the shop vac 2
1/2" hose to the fence dust collection port. Have a 4" Y fitting built in so that one branch picks up at the bottom of the router enclosure (build something of a slope into the sides to help funnel chips down to the opening) and the other branch cobbled into the bottom of the shop vac's bin to empty it.My big question is - what would this configuration do to the shop vac? The normal air flow is coming in the inlet hose, into the bin, through the filter, and out the outlet vent. With a shop vac connection in the bottom of the tank, the flow would branch - some going through the filter and out the outlet, and some going out the DC connection.
Wondering if someone on the wreck has tried something like this. How would it actually work in practice? Would the DC flow starve the shop vac blower for air? And if that was the case, would it basically end up being no different than having the DC connected to the fence pickup through a reducer? I've read that a shop vac has higher suction, but a DC moves more air, so it seems that a shop vac would be better suited to pulling chips out by the fence opening.
