In the "how to splice" webinar, the wiring fundamentals course and practical harness construction course Zac refers to the Delphi #12085271 ratchet crimper as the best crimper to use for reliably crimping open-barrel splices.
Can anyone recommend an alternative crimper that's easily available in Australia? The delphi/sargent tool looks great, but it will cost about $150+ AUD to get it landed here and take a few weeks (from all the sources I have found).
I have worn mine out. And need to get a new set soon. I will probably get the same again, as these have done me good for the best part of a decade now of daily trade use.
