Bruce I used my rod box as a spinner for a while.. I had them set up inline like yours .. They never spun at a constent speed because of the weighting of the plugs .. They would slowly turn then woosh as the belly weight momentum took over .. This would give me sags in my finish .. drove me nuts .. Tried it again staggering the belly weight positioning,, somehow they would find eachother again .. Maybe it was the crap sb 112 I was using.. you obviously have avoided this ..maybe not enough supports .. i duno .. into mirror coat now .. bet you knew that ..
