hello all- i just got a HF 2hp dust collector with the bags and all- ive read through the threads and infact i started athread on this awhile ago. my question--should all the hose/pvs/metal ducts used be 4" the samse as the dust collector motor outlet/inlet? what would happen if i ran say a 3" pve horizontally and had a 2" flexible hose going to each machine at one big table. the 2" flex hose would have a larger adaption at the part next to the machine. each 2" piece coming off the main #' piece would have a gate. the 3" would continue and end up under the grinder with a spark arrester inbetween. Would using smaller hose sizes be dangeruos cause of the suction?-and as for as the copper grouding goes- i need to run the wire through the entire system and groung it to each machine and motor? i am long winded -sorry thanks mark i plan on hooking up the outtake to go outside -eliminating the bags altogether.
