Excellent little Groove Pulleys!
I used a number of these groove pulleys to build my own hand-held guide for controlling how I wind magnet wire onto a bobbin with a coil winder. They not only guide the magnet wire perfectly, but relieve the majority of friction that you would normally used with your hands. I bought 10 of these pulleys, but only needed 5 because I wasn't sure that some of them would function properly. As it turned out, there was only 1 that had some internal problems, the others worked just fine. As you can tell in the pic, I used some nylon standoffs with small bolts, washers and nuts to mount them onto my fixture. They seem to be well made, I'm very happy with them!
