Todays update is short, but a little progress. I have worked a little more refining the control panel. It will sit on a shelf about 8" higher than the bottom bracing on the cart in the pics. I may put the little monitor down there as well. It would be tilted to be seen from a standing position. Keyboard will be covered with a big ziplock bag or maybe some press and seal. That stuffs pretty neat.

Anyway, here's the pics of the cart after I got the bottom welded up. The legs are some sort of overhead door track that I picked up. The bottom frame is just part of an old bed frame. I got these nice casters from Surplus center for $4.95 each. These are very good casters with a 200 + weight limit each. Nice rubber tires. These are made in Australia.
