On the topic of crimping big terminals (4 gauge or bigger)
Is it even possible to use anything other than a vice? I've always had to use a vice for them, no way my box end's were closing those connectors....
You guys got any tips?

Oh, and after many botched crimps, i figured you you have to do one half first, then get the next one to fold over it, then tighten like heck... it's worked perfectly since....
