I was telling my Son today about this mount you made and how I like it. Ours is on a rolling cart and we feel it is too low to use easily, so we are going to do something along the lines of what you have built here. Ours is an electric ProTools 24 incher, and we like it and would probably use it more if it were mounted higher. Good idea you had there.
I saw something on the other forum that also I want to build. A guy made a clamp on guide out of angle iron that he can move along the lower tubing part of the bead roller. It sure looks like it helps to make straight beads.
