I've been using thinwall DWV plastic (Sch 30 or even 20) and excepting
for the static electricity annoyance(*) works fine as well.

(*) But it's no worse than the flex plastic, either...


I wrapped some wire around my planer discharge chute because of the
static. One end is grounded to the body of the planer. It helps quite a
bit.

Bill Pentz's site had a recommendation of putting a piece of metal tape
down the pipe on both inside and outside then connecting them with a
through bolt. Sounds like it worked well.

When I set up my collection system 14 years ago, I used ThinWall 6
inch PVC drain pipe with 6 inch flex to my TS and BS, 3 inch flex to
the other stuff. I ran a copper wire inside connected to the Dust
collector and each machine. In a couple of years I started getting
clogs where stringy stuff wrapped around the wire and hung on,
gradually growing. Fortunately I used only slip fitting at some of
the joints so it could be taken apart.

I removed all the wire and have had no problems--never got a shock or
spark, even with the 3" flex which I use for vacuuming the floor and
around the lathe. I have gotten a shock in my brother's shop while
using his shopvac.
