John,
These is the sort of thing I am suggesting. The 5-600 amp ones are better.

You will see on the ebay one that it has a section of earth strap connecting both sides of the jaw. this stops the clamp from getting so hot.
Bet you can get them cheaper locally to you.

These pics are much clearer than my bad attempts at digital photography !!

The one on the left in the attached pic is better than the one on the right as it has a brass connection bolt.
You need to tie the cable to the handle so that it doesnt flex on the connection & fail in time.
I suspect you could make a set for under $100, Every time you help some one, offer to sell them for $250.
Just a thought.

Hope that helps!!

Good Luck !!
