CONSTRUCTION UPDATE
I started work on the desk last night. I screwed/glued the 1x1.5's together to make the front supports and cut the holes out of the deck boards I'm using for the back supports. It looks like I will only need one set of the back supports. Just one set seems to be plenty stable wedged onto the arms of the treadmill and that's without affixing them to the desktop. In a rather serendipitous turn, I think my ineptitude with the roto-zip which resulted in a very rough cut actually helped the rear supports grip better on the arms. Rather like a set of teeth.
Next up I will cut the desktop to fit. Right now you can't see the control panel at all. So there will be one rectangular cut at the top to open that up a bit and an oval cut at the bottom to give me some extra room to stand.
After that we prime/paint the various parts, move the treadmill to my office and with any luck I'll be posting from a fully operational
death star treadmill desk by the end of the week.
I think I've violated at lest a half a dozen safety warnings so far during construction. It feels good. My inner Tim Taylor is showing....
