Installing a Dust Collection System

Control the flow

Control the flow

For maximum efficiency in a branched system, shut off the flow from all ports except the one in use. To do that, install blast gates.

You can buy metal or plastic blast gages for various pipe sizes from a number of woodworking-equipment dealers. Or, refer to the drawing below to build a wooden blast gate.

The connectors shown are made from a PVC pipe coupling cut in half and epoxy-glued into place. You can alter the dimensions and couplings shown to fit different sizes or types of pipe.

To mate the 3" or 4" system to most of your tools, you'll need hoses and adapters. The best way to do this is with tapered (not stepped) transitions.

I have plumbed a 2 1/2" pvc system. I am able to connect to the 2 1/2" blast gate using a 2"x 2" rubber connector but having trouble getting from the blast gate to 2 1/2" hose and to 1 1/2" hose. it would be nice if some one made standard PVC connectors to Standard shop vac sizes.

To bojinks1 Try heating the duct work slightly and inserting the dust collection fittings into the duct work. This should work if you purchased 4" drain or pvc pipe.

Use a rasp bit that attaches to your cordless drill. just run it around the inside or outside until it fits. Usually its only about 1/32" that I had to remove to get them to fit. Use a tapping block to fit the two pieces together so you dont mar them up.

I purchased the drain and sewer pipe along with fittings to connect the pipe but have a problem getting the fittings to match any of the standard dust collection fittings available through known outlets. for example I can't mount the blast gate to the pipe.
