Mike,
Thanks for that, I have mainly ratchet crimpers, but then I use them lots for work so its worth spending the cash.
Paul,
I have a set of those its for the next cables sizes up I'm struggling to find one for.
One option is to fold the tabs over and use a 10/16mm ring terminal crimper to form the indent but that would be localised and not the whole length of the crimp, being in my day job having seen the result of poor crimps and the damage it can cause, im a bit @nal over things like that, so its the right tool for the job !!
Could try one and even add some solder into the equasion to see what the result is
Regards
Les
