hi mark
My system consists of two size pipes which i can separate though a blast chamber with the blast gates either shut or open the 100mm or 50mm , the 50 mm can be seen in pics .
I use the the 100mm side for the planer, saw and sanding machine at the moment , having said that at the moment the work centre saw is connected to the 50 mm ( temp ) my next major purchase will be a new table saw , when i have it then its my intention to connect it and the band saw to the 100mm supply through different blast gates but on the same run .
My system is powered by a record DX5000 twin motors it works fine on the 100mm side as well as the 50mm side when both motors are switch on , i also have connected into it a shop hoovering system as is shown in the pics , i connect a length of hose 7.5m to it where it can reach all of the shop .
when my flexible extraction pipe arrive on Monday the bansd saw will be (temp) connected to the 50mm extraction side till i get the new saw and then it go over to the 100mm side this will then complete the extraction system , which when completed i will post a thread here from start to finish .
I intend to connect either system to both outlets on the band saw and see how good it is and make any alteration that hopefully wont be necessary . hc
PS hope you can understand all that any queries please ask and I'll do my best
