Do not tin wires that you are going to crimp.

Do not "double strike" when you crimp.

On this last, why not? Is there some weakening that occurs?

Depends on the crimper, but a good one only needs one squeeze and yes
the second squeeze can make the joint less secure.

A good solid strong single Crimp 'sets' it's
Contact {Compression} Points and nothing
more is required. {Optimum}

The second Crimp often disturbs these Contact
{Compression} Points and may in-fact reduce
the hold {efficiency} of some or all of them.
* Often nothing is gain and sometimes there is
a loss of a solid crimp. {bad crimp job}
+ The Double Crimp is twice the work with no
real improvement in the product. {wasted labor}
