I made mine such that I could rotate it to make all the fabrication and welding work a lot easier. This was one of the smartest decisions I made - really helped the complexities of the fabrication process, the boxing plate installs/welding, etc..
The end stands are made like engine stands (and I made them such that when I don't have the jig together, they are engine stands). I used the construction of the stands and the jig as my first TIG welding project (had done a lot of oxy-acet and stick before). The cross bars have adjustable frame holders - so they can be moved to handle any width/style of frame - the first being a custom 34 frame I built.
Also, it comes all apart as I knew that I would not want it taking up room in my shop and it is too heavy to move if it is all together . . . anyway, here is my take on it.
