Ok, dbhost and Purplelev, The verdict is in. It works like a champ. Although the 4” hose seems to have dropped some suction power, when down sized to the 2 1/2” hose even through the bast gates it does a great job. I have a little more tweaking, but I am going to build the stand for the DC, so I can put the Gcan under it. I only have to pipe one side of the shop. 20 ft of 4” hose, 1-Y, 2-blast gates, 2- 4 to 21/2 adapters, 20ft of 2 1/2” hose, and maybe a coupler.
Materials for the dust separator. 32 gal. Brute Garbage Can, 1- 16” circular piece of some type of wood or hardboard, 1 – 3 ft X 3” schedule 40 pipe, 2 – 3” 45’s, 1 – 3” long elbow, 1 – 3” coupler, 1/2” foam backer rod, d contact cement and a 6 X 6 piece of 1/4” hardware cloth.
Take the coupler and cut a 3/4 wide ring of of each end. These are to be slid up each pipe and PVC glued into place to secure the pipes and 45’s to the garbage can lid. Apply the contact cement to both the lid and the backer rod to secure them in place. ( I started with carpet tape, but that was temporary).
All holes through the wood baffle, are 3 !/4 inch. Staple the 1/4” hardware cloth over the center hole in the baffle.
When testing, the 4” hose sucked up the 3” plugs with ease. The drill press cleaned up nicely with the 2/1/2” hose. I imagine that the implode problem came from not using a Rubbermaid Brute can or hooking up a 3000 cfm unit. The DC strains when both blast gates are closed, but I think enough air gets past. Sure is going to make things easier for sawdust removal.
I’ll run some pictures of before and after trials tomorrow.
