Onieda is where I sourced the 24ga pipe. They sell it in 48" lengths for anyone who is shopping for that. I read conflicting accounts of the best recommended gauge to use. In hind sight, I kind of wish I had gone with 26ga as it sounds easier to work with and should still be heavy enough for my 3hp cyclone.
I actually tried the zip tie method but didn't have success with it. I bet it would work well on 26ga material though.
After dealing with all of this, i'm happy with the result but if I had to to it over, I might try and spring for Nordfab. I don't have a very elaborate DC system yet and I'm extending it as needed so the cost spread out over time wouldn't have been that painful. Oh well, I'm breathing a lot easier in my shop now.
