Dust collectors in a woodworking shop A very good idea. I put one in my shop a few years ago, and it does a terrific job. Its a Delta 1 1/2 HP unit,which I bought on sale for around $200.You dont need to spend a thousand or so on one. Go to your nearest woodworking store and look around. Good ones made by Delta,Jet,Penn Industries,Grizzly,and others. I used 4 inch PCV piping to pipe up my shop.And shutoffs at each power tool,so I am getting the full suction when I am using it.Install runs to your major tools,tables saw,radial arm saw,joiner,planer,sanders,etc.You will be surprised at how much dust they collect and how much cleaner your shop stays.And oh yeah all that dust you would be breathing in.Also my neigbor likes it,cause when I empty it out he tills the sawdust into his garden.
