I have finally decided to do some proper dust collection in the shop and it was a painstaking process. I have ordered the Oneida V-3000 system (which hasn't arrived yet) and will do a review on that when it shows up. Onto the pipe; I ordered it through www.blastgateco.com, which I found on the internet. The pipe and the customer service is awesome to say the least. I called the company and they (Dan) had me fax a sketch of my shop to him and in roughly an hour he had an invoice ready with all the fittings etc. that I needed. These folks are a 5 person shop that make the fittings in house, which I thought was great, the straight pipe is 28 gauge spiral, all the fittings are 18-20 gauge, great product! Price.. What you see here cost me $380 which included shipping to Va. from MI,( which is much less expensive than anywhere else I could find on the net, not to mention made in USA, Union labor and a small business). This will hook up 5 machines, 5 aluminum blast gates etc. and a section of 6 inch hose to go from the cyclone to the start of the pipe.
