A really easy method is to use some kind of snap-in clip ('C' shape on
its back) to fix the tube - plastic nail-in cable clips, mounted
upside down (i.e. reverse the nail) are ideal. You just snap in the
tube as you wind it. Suspending the coil of tubing above the work
prevents twisting & kinking it just 'falls into' the coil with very
little effort.
