I am running all my lines for a dust collection system, planning on getting a HF DC unit with 4 inch lines, but my router takes a 2 1/2 inch. I plan on putting a "Y" to the router anyways with one 2 1/2 going to the fence dust port and the other 2 1/2 going under the table into the enclosed space with a funnel under the router to catch anything coming into there, so my question is will the two 2 1/2 inch hoses coming off the 4 inch be ok, or do I need to do this a different way...
