I am having good luck with the US Cutter 12" that I got, but it has no feeder rollers so I let the roll of vinyl free roll on the desktop behind the cutter as it feeds in. Is there a set of feeder rollers available for this that I can just put on the desk and then lay my roll of vinyl on...kind of like what my rock tumbler has? I know the larger cutters have them on their stands, but what about for this smaller cutter? Any suggestions on how to make one if not?
