I've converted all of my DC wiring to Power Poles, so I've put 
together more than a hundred of these connectors. There are three 
sizes of pins that fit the red and black shells used by Elecraft. 
The small size is best for wires smaller than #18; the middle size 
(most common) works up to #12, the larger size goes up to #8 (and 
can be a very snug fit in the shell). I've always bought them from 
hamfest vendors, but there are several vendors who advertise in QST 
who sell them. They usually come in packs of ten, or ten pairs. I've 
never crimped them, always soldered.

Remember that voltage drop is proportional to length, so shorter is 
better.
