Topic tags/keywords: tablesaw dust collector dust shop safety

Hi Folks,

I have all the materials to get started on building a real dust collection system based on Phil Thein’s design.

I purchased a HF 2HP DC about 2 weeks ago. I am very pleased, I connected one port to the Table Saw (now Ridgid will be happy that it will not blow up) the other port to handheld floor vac attachment. I have blast gates on each hose. Using the floor vac is amazing, the suction is close to that of a shop vac, it will suck in a rag or screw from 5 inches away, as you might expect the input vent gets clogged a lot, and the screws make a lot of noise.

I need to start the permanent setup. I would like to take baby steps if possible. So I am thinking that the first step would be to put a simple separator on to the base system, possibility with the Thein “under the lid” cyclone.

My question is I would like to keep the 2 connections I have, and in the future go to 3 connections. Would it be better to a 3-Way Dust Collection Junction, or open 3 input connections in the lid ?

Not sure if its exactly what you’re asking for, but maybe a setup like this could give you some options. Whenever I can afford a DC system I think I’ll do the same.

Hi Brian,

That answers one question, how to switch between between runs/machines. I wish the guy would
have added more detail, it looked like a really neat device.

My other question, would it be better to have multiple holes in the the trash can lid, especially
if you wanted to keep 2 or more lines open.
