I have been looking at these type of videos for a long time and have one complaint. Notice that the guy feeds it with only three strands of the same type and gauge of solid wire.

If I ever get the chance to test out a granulator I intend to bring the biggest nest of crap wire and see how it handles that. I have had a couple of conversations with a guy who had several granulators and water tables for separating. He said there are several obstacles to overcome. You need steady supply of wire. It needs to be consistent in quality, he said sometimes you get a lot of trash hidden under the good wire.

One thought I've had is if you could come up with a good source for just the plug ends that would work 73, Mike
