We got a small 2'x1.5' cast iron plate with a used Bringheli BB post, both fairly inexpensively. We have not used it yet, but it is probably the smallest practical size, with 76cm on the diagonal. We will need to rotate the frame around during alignment.

In theory a long channel (like the Bringheli I suppose) is all you need I think, as long as you can rotate the frame around some post and have some space to move a surface gauge around (or use finely threaded screws from the bottom?). And I would tend to think the steel channels you can buy are sufficiently flat (i.e. grounding them flat might not be necessary... considering how we true and dish wheels). I also envision making a cheap BB post out of old BB cups with the threads ground off...
