Bugman,
I have a rotisserie motor for that purpose. But I am not going to use it. I have a rod turning motor that I will make mine out of. I will send you a smaller clip just for show and tell. It is exackery what you have in mind for smaller alligator clips. It will show you what to get for what you want for the 14's.

By the way Kelly, you can have the rotisserie motor if you want it. I have absolutely no use for it. Let me know and I will mail it to you.
