Having written a few articles on crimping, before this one, I knew I needed to find an "affordable" tool for making these terminations to avoid getting "blasted"...
For these crimps I personally use a heavy duty ratchet crimp tool with modular dies but they are more expensive and many boaters, based on history of my articles, would resist this expense. This tool I find to be a tremendous value, and one that makes a very good crimp on small terminals. I sought out this inexpensive, but also good quality tool, specifically for this article.

The tool is made by GC Electronics and is called the D-Sub/Double-D Service Tool. The model number is 12-464. I paid $22.00 for mine at HR Distributors in Portland, ME. They ship anywhere.
