Everyone's a critic. I went to the hardware store and bought some washers that slip over copper pipe. I am going to notch and weld the washers to the inside of the frame. I will run all the wires and tubes through the pipe. While doing that, I found a great idea for the floor boards. Pictures in the next couple of days.
Just heated up the bar, and wrapped it around some 5/8ths round bar. Then used a cut off wheel to slice them, right down the bar. Knock them off with a hammer, and bend them flat. Easy.
