Metal T-Frame Basics Answered

Hi there, I'm new here and pretty much to DIY in general (except for general repairs) - I'm planning to build a glass dry-wipe board with a simple aluminium T-Frame and need a bit of basic advice. Not knowing the lingo of the trade, its been very hard to find suppliers/information and my research seems to have gone as far as it will ever get, so I figured it was time to ask for some help. I've managed to find a supplier who stocks 25mm square al tubing and was wondering about the best way to construct the frame. My design for the frame is extremely simple - it's just a t-frame with a single crossbar which will run below the pane of glass. I have access to a reasonably well equiped workshop, but unfortunately no welding gear (I hear that al is difficult to weld anyway) which isn't too much of a problem as I would like to be able to deconstruct the frame. I would appreciate any tips which may be useful to a newbie, but mainly I need to know how to fix the al bars at right angles in a non-permanent manner. The desk which I'm sitting at right now has some sort of threaded inserts at the end of each crossbar, allowing it to be bolted a right angles to the frame. I tried googling these inserts, but couldn't find anything which seemed relevant. If anyone could point me in the direction of these inserts or provide an alternative solution, it would be very much appreciated. Thank you

Try searching for structural tube framing. What you are talking about is a perfect situation for t-slot framing (8020 faztek et al). The t-slots allow you to connect the pieces with 1/4 20 bolts. Check out the links and don't ever forget McMaster-Carr.
