I'm making a lightweight gimbal head similar to that of the lensmaster RH-1. All I have to do now is make an adapter to go from tripod thread (can either be 1/4 or 3/8 as mine has both) to a longish 3/8 thread to accommodate the width of the flat bar and a handwheel nut. Tried looking on net for one, but could only find short adapters.
