That stuff looks similar to US rigid conduit in that it’s threaded. I bet it’s rather thick walled.
How hard is it to cut?
I realized in the various threads that a distributed build, and pre-arrival pre-builds are a possibility.
I’m really excited about that prospect as it is get-aheads and also brings out the best of what the community can achieve when we work together. The collaboration is one of the most fun and rewarding parts of it for me.
I need to decide on a printed parts size fairly quickly, so let’s try and decide between 30mm and 32mm tube. Whatever we pick, we’ll start working on pre-builds.
I propose that I’ll bring partially pre-assembled core and YZ plates, and that we get an LR4 beam assembly started on the UK side.
I really love the idea of putting addressible LED on the bottom of the beam, and if we start pre-building we can have all that ready. Arrival becomes an integration and assembly session.
I’ll get the final dimensions of the table that we’re going to get and will translate that into a proposed size for our build.

Though if you need to bring tools we’ve failed as a makerspace!
) So maybe throw one of those in with the mounts? And while you’re at it, another one you can resell to me from Ryan’s shop plus a shipping and handling fee for carrying it across the Atlantic would be sweet! 
Being one of the people that built full sheet capable to avoid the “how big do you really need” question, I’m not sure what less than full sheet size we should be trying to cram into it - beam wise anyway. I had been wondering about a 4ft (so it could still eat a full sheet, just in several bites) by 2ft “portable”, but cramming a full width beam into that space isn’t going to happen, so you’re probably on the money with 3ft by 3ft … if we think it won’t cause trouble.
