I recently purchased a wire crimper for wiring frames. It looks like most of the major supply houses sell this one or one similar. This one has helical (angled) gears and the teeth on the gears do not mesh. I tried crimping one frame with it and this thing seems absolutely useless. I've seen pictures of crimping tools with straight teeth that mesh together and I expected these helical teeth to mesh too. The teeth meet in an 'x' instead of // though. I though at first that the manufacturer might have mistakingly put one wrong gear on but, when I looked back at pictures on the web site, they match what I received. Am I missing something or is this design completely unusable? I find it hard to believe that the manufacturer or any supply houses selling these have ever tried to crimp with it or they'd see the issue. Along the same line, does anyone know where I can buy a crimper with straight gears?
