I'm setting up a new shop. I have to run dust collection pipe, electric, and air to two different groups of tools in the middle of the shop. In my old shop I had secured the duct and conduit to a 2x2 aluminum post that was attached to the floor and ceiling. I also had one area where I used unistrut in the same manner. Both options were kind of flimsy. I was considering making a couple hollow wood posts so that I could run the wire down the inside of the post and secure the duct to the side. However, my supply of time and money is running low and now I'm just looking for the best, cheapest, fastest option. I'm considering simply attaching the duct at the ceiling and floor and securing the conduit to the duct. I doubt it would be any more flimsy than the aluminum post or unistrut I've used in the past. Thoughts? Any other suggestions?
