Did a thorough search in archives but did not find answer to this specific question. Have the Delta 50-760 but don’t want to roll it about especially since I’ll use a pre-seperator. In FWW review Standish says DO NOT us these 1 1/2 HP DC’s as central collector. Do you agree and/or have alternative experience?
Longest run would be 20′ to my 5 HP Unisaw, shortest about 6′ to my 12″ planer with jointer, router table etc. in between. One machine at a time with blast gates. Metal pipe is outside my budget so will have to use either 5″ plastic hose or (reluctantly) 4″ (can get 5″ but more $ than metal) PVC pipe. Have thought about cutting opening in motor base to accept 6″ flange. TIA

I have the Delta 50-760 and have it set up as a central collector in my shop. I've pointed the inlet to the collector upward and run 4" PVC overhead to blast gates near the tools. From there I use clear flex hose to connect to the tool, each drop services more than tool - I move the flex hose to the tool.
Suggest you try and locate the collector close as possible to the table saw, as it is generally the most difficult tool to collect from. The run to my table saw (and router table and planer) is about 15 feet including the ups and downs. My longest run is to the jointer (and bandsaw) maybe 30 feet.
Overall, I'm very happy with the performance of this set-up. At times I may leave more than blast gate open and it still does the job. The performance could be optimized by going to 5" or even 6" pipe on the mains, but given the cost tradeoff I see no reason to.
Thank you. I'll be running the pipe along the foot of a wall and a short distance out to the machines. As I'm currently laid out it won't be in my way and avoids extra length of overhead runs. So, your response is encouraging. Did you have to glue the joints? I ask because one thought is to try the 4" plastic pipe and upgrade later if necessary.
I did not glue any of the joints, I put a couple of short (as to not to penetrate inside the pipe) hex head sheet metal screws in some of the joints where there was some stress, but mainly just friction fit worked well. I needed to wrap some duct tape to build up the diameter on the blast gates - I think it was on the side where they meet the PVC.
If you can, stay away from the corrugated hose for the main run(s). Especially that 20' run to your table saw. The corrugation really robs the system of CFM.
