I’m building a new workshop and I want to install a super vac system. The price of a good cyclone is bad enough, but what’s with the conspiracy of the tubing?

I understand the dangers of dust, but has anyone got a solution that’s cheaper than buying customized tubing for the dust collection system?

My last shop in NC, I used 4” sewer pipe (PVC) and tried to ground it by running a braided copper wire throughout the system. This may have solved the static electricity issue (maybe not – at least I never had an explosion). However, I was plauged by constant plugups due to the wire.

To me, there’s absolutely no reason why a 4” x 5 foot should sell for 25.00 +. A 10 foot peice of PVC costs about 2 bucks. The blast gates have to be built up a little (used duct tape and screws).

Anybody got a better idea that won’t pose an explosion hazzard?

I’d stick with the 4” PVC and forget the grounding wire. It’s not really necessary for DC’s under 3HP.
(so says an article in FWW)

PVC I think is becomeing more widely accepted in small shops. If it still concerns you, regular HVAC ducting should work, it’s just tougher to get a good seal at all the connections, but can be done.
