Okay, I have three Ergotron LX wall mounts that I won't be able to use for the forseeable future (Rented buildings, yay). However, in the 'your room and computer' thread, I saw someone (Sorry, I can't remember the username..) had constructed their own desk mount for holding some monitors and it got me wondering. What I'd started considering was a piece of scaffold pole that would go through a hold cut in my desk, so I can keep the desk as close to the wall as possible. Obviously I'd need a stand at the bottom, the question is, how big (or heavy) does it need to be to offset the weight of three monitors? They would be three G2400W's, so ~9kg each, the arms are probably 4-5kg, and I'd be mounting them on a piece of sheet steel (4.5mm thick), which would be welded to the pole, and there would be some support limbs of course. I was thinking, for the support limbs, one to each corner, going back to the main pole? Any thoughts? I was thinking box steel for the base, as that should be pretty weighty and provide a decent enough standing area. Now, the base needs to remain detachable from the main shaft, so I can get it and the desk apart when I need to. I was thinking a short piece of the same tube for the main pole, with a piece of tube inside it to hold the two together, and a clamp to stop the main pole turning. Good idea or bad idea? I've not got anything drawn up, being at work and lacking any decent software for doing so, but. Any advice?
I think that was me, is this talking about? what youre What you're suggesting sounds good, I think I made the "legs" of my stand 400mm long and at 120deg to each other, it's very stable but my monitors don't move. I would suggest making the stand as big as you can because you cant have too much stability but having too little would be a disaster. If you need any more info just let me know.

That is indeed the one that I was thinking of! Hm, okay. I've been looking around the work store room, since there's all sorts of crap in there, and stumbled across a rather large base for a TV trolly - akin to http://www.rocheav.co.uk/images/products_thumb/bt8051.jpg that, but with a lot thicker/wider construction. I'll grab a picture if I get a chance. It's easily three feet across, by two feet deep. I wouldn't be using that specific one, though, it'd be more work to modify it to my needs than to just build my own, but it might serve as a decent starting point. As for the movement, I doubt they'd be doing that much, but yes, they would be capable of being mobile.
The thing about them being mobile is that you would then need to plan for stability in the worst case scenario eg, all on one side and as far forward as possible which means you need a much larger/heavier base. Moriquendi
