Buy one of those narrow paint rollers the one that is like 3 inches wide but it needs to be the full size type not the little foam ones. Remove everything from the handle add the amount of blades you need prolly about 10 you will need to space them, up to you but washers work well make sure they fit without being too sloppy on the shaft, mark were your last blade/washer is on the shaft drill a small hole for a cotter pin and cut off the excess now you have a relatively safe way to cut your tails, but again as I mentioned the up front cost is a little pricey but worth it if I find mine I'll take a pic for you. Oh a the blades are round fabric blades look on the net to find a good deal on them.
