Here's some more detailed shots of the camera arm. @oldturkey03
My camera arm measures 19.5in in length, and is cut from the leg portion of one side of the walker. Each walker leg is about 30in long from bottom to top of the handle. I wanted to get as much use out of the walker as possible, so I decided to use whatever scrap pieces for a camera gimbal stand, which uses a similar diameter tubing. I measured 19.5in from the top handle toward the bottom of the walker and made a cut with a standard circular pipe cutter. This left me with a 10.5in segment for one of the legs on my 3 axis gimbal stand. I determined the desired camera arm length after some mockups with wooden dowels.

I found that between 18in and 19.5in is the sweet spot for fitting the entire width of my ESD mat within the field of view of my camera. The field of view on my Panasonic GH3 is slightly different from my GH4 and slightly different from my LX100. That 1.5in of wiggle space allows me to compensate for the difference in video framing between cameras, and in case I have an object that overhangs the ESD mat, which is flush with the edge of the table.
I decided to preserve the curve in the tube because it would provide some additional strength when the arm is folded out, and prevent the arm from rotating and ruining the camera image. I decided to cut the tube about 4in from the side of the tube.

I also decided to cut the side of the walker that already had a hole centered and cross drilled. The hole was 3/16in in diameter, and I wanted to keep everything 1/4-20 because 1/4-20 is common for camera mounting equipment. A stepped drill bit really helps in this case. I also had a bunch of 1/4-20 bolts and threaded rod lying around, so that helps in the decision making process :D.

In case you were wondering, here is the bottom of my 3-axis gimbal stand, made from left over scraps and a 3 way stainless steel boat rail fitting.
