I use several small tools in the same general area of my shop and have been connecting and disconnecting them from my shop vac when used. I want to setup a PVC header with shutoff valves, to connect each one of them into, so that I don't have to do the connecting and disconnecting.
Sort of a mini dust collection duct system. I have done some experimenting with hoses and it appears that I have plenty of suction even when using small, long hoses, so the problem won't be length from the vac.
My question is with grounding for static charge.
Will I need grounding with this type of setup? My maximum header length will be about 20'?
Do I run the ground wire inside the pipe and then exit the pipe at some point and go to ground or can the wire be attached to the outside of the pipe?
I haven't had any problems with static using the hoses but after seeing some of the threads about grounding PVC on the larger systems, I wanted to ask.
Also, I haven't seen any thread about using a small duct system like this. I would appreciate any other general information from someone that has done something similar to this. Advantages/Disadvantages, Tips, Pictures would be great.
The header will have the following tools attached to it:
Compound miter saw, circular saw, RO sanders, routers, or anything else small that has a dust port connnected to it.
I don't really like the boom idea, because I see where it could get in the way at times. I would rather have my hoses drop down to the center of the table and still be able to get around all four sides of the table without having to work around the boom.
