I had my boom arm attached to my clamp rack just to see if the design would work. Now I have attached it to the mft. Still thinking I want the mft on wheels, will work on that next.
gxgn, The arm is 3/4 emt conduit, the top clamp is 3/4 plywood with a 5/16 bolt in the t track with a knob from woodcraft. It has a 1" hole in it for the pipe. The bottom is kind of a box on its side with half straps holding it to the leg. I thought about putting it on the floor but decided to try this. I like this better than having it fastened to the vacuum.
