> Here's part 2 of my idea - with a much simpler design. Opinions? Discuss. Your machine can only do one end of each wire and uses two cutters/strippers, so it is more complicated. Their machine (from the youtube video) is clever because it can do both ends and both strip and cut with one cheap tool. It can also be programmed to pull off the stripped insulation if necessary. That's why it has pinch roller drives on both sides of the cutter tool. What you could do is to use two solenoids for cut and strip respectively, acting on the same tool, as that would be faster than the screw drive. It would be much louder, however.
