Hello,

I read the wiki section about crimping - very useful, thanks - and it
said to use a ratchet tool to ensure the quality of the crimp. I have
seen ratchet crimping tools that are colour coded for insulated crimps
but I wonder, what are you supposed to use for non-insulated crimps?
Is there a ratchet tool available for those, or do you have to use
those multipurpose wire stripping, bolt cropping, pliers?

Thanks,
Stephen.

Ratchet tool. Same tool, just different jaws.

Vehicle Wiring Products are a good source for all this stuff.

You just need a different version of the tool:

Much the same idea, same ratchet, different jaw profiles.

It really depends on what you mean by non insulated ones. There are
thousands of different crimps for various purposes.
If you mean the fairly standard car 1/4" etc spade connectors, I use the
PR3 one on the page below which does a super job. But economies of
production scale means it's much more expensive than a pre-insulated type.

are the ones I have - Davico are a decent make and the tool makes a very
convincing job of it.

Thanks everyone. Sorry I didn't look hard enough, I could have sworn
that I only saw tools for insulated crimps. I've never heard of VWP
ltd before, so thanks for the recommendation. I will be using the
standard 1/4" spades. Thanks again.

If you are using the standard 1/4" 'lucar' connectors as used on car
wiring then the above crimp tool produces a 'factory' perfect crimp, using
the standard lucar 1/4" terminals, as sold by the likes of VWP. For other
terminals which are similar but designed for single core mains wiring,
others might be more suitable for less cost.

Basically crimping is a bit of a black art and there is no such thing as
a 'one size fits all' crimping tool. And a badly made crimp is worse than
useless. Better to use a screw or solder connection. But those aren't as
good as a well made crimp connection.
