Nothing new or earth shattering here but liked it because it is so simple. All you need is a couple of alligator clips and a length on coat hanger wire. Bend the wire like shown. Example I saw has the circular bend at the bottom. Not exactly sure why but went and did it that way. Used a deep socket in a vise.
Crimp or solder two alligator clips on the ends and you're done. Told you it was simple.
