Crimptastic!

After a few days, my new crimping toys tools arrived in the post. Here's a joint from a couple of years BC (Before Crimptool) :

However, that was before the RVFM HT-225D, which I got from Rapid.

It has the correct 'B' shaped jaws to make proper crimp joints:

To use this effectively, you need a set of crimp pins, and you need to carefully strip and trim the wire, like this :

Then you need to insert a crimp pin into the appropriate jaws - note you don't always need to remove them from the strip, I found them easier to handle by bending a single pin away from the strip.

Then, insert the wire : I marked a small dot with a sharpie to mark the appropriate depth:

Pull the handles together until they're all crimped - rinse and repeat:

So much easier and more efficient than the manual pliers/solder method. They're not 'perfect' yet - according to the spec I've got a little too much insulation in there - but it's a damn sight neater than my first attempts a couple of years ago :-).
