I’ve decided to build the International version because I want to use smoother stainless steel tubing vs the US EMT. Has anyone been able to find a US sourced for 25mm tubing? I would even consider having it shipped from another country if the price is right. Thickness is not really a concern because I plan to reinforce the tubing.
In lieu of the 25mm, would 3/4 180 grit brushed work for you?

I’m considering these myself…
