RE: Paper tuning stand
You might want to reconsider having the roll of paper attached. The reason I say that is when I built mine out of pvc and tried to add the paper I had to make the stand too heavy to be real portable. Since I' ve taken the roll off and cut it down to the size of a standard newspaper sheet. I use binder clips to attach the paper. Now I can change the paper fairly easily and don' t have such a heavy frame.
