I took a couple of angles sections of steel out of the hair blending machine and used them for uprights. My brother and I had debated on this, he won out on the dual motor design which will give the machine less of a chance of kicking out of square. I won out because I can still take all of the bases out of the machine and really tall parts that are on the ground or install a vacuum base, the scanning bed etc. etc. as I wanted.
Here are a few pics of the base with the Y axis and uprights for the X and Z axis.
