Without seeing the kit, I think a piece of aluminum flat stock would work. Drill and tap it for a stand at a convenient location, and mount it to a panavice stand, or something similar.
That might be a better and simpler idea. Mating the 3 structures together the way I've done it and having them all align properly has not been the easiest thing to do. Unfortunately the other problem I have is I don't have anything really good to cut aluminum with other than a grinding wheel.

You can get aluminum flat stock in various sizes at Lowe’s. They may have something suitable. I think they even cut it.
Found and photographed the instructions (don´t have a scanner at hand). They consist of 4 pages. With all the copyright topics being in the media, I don´t want to publicly post any graphics which are not my own. So anyone who needs the instructions send me a PM including your email adress.
