Besides is there any other vendor that will sell me all the electrical and mechanical components to attach to my own 8020 t slot frame and make my own machine?

I can weld and it would be cheaper and stronger IMHO to just weld it out of steel 1.5x3" tube which is a fraction of the price and much stiffer than 40x80mm t slot extrusion. I would keep some 8020 tube for ease of assembling, but most of the table can be buildt out of steel IMHO.

Thanks for any insight!
