I made my paper tune holder out of PVC pipe glued together to form a frame and my spin tester out of some kinda rollers I found at Wal Mart in the hardware section- they work great only about a buck apiece per roller. They are about an inch or so long and have two round wheels attached _ i think there made for doors or something- bought two sets mounted them to a board and top quality spin tester for 2 dollars & 12cent tax
