Guys,
Home Depot has lead test kits for 25 bucks, it's a chemical test that's quick and cheap. It's original intent was to check for lead paint.

If your Jig is painted, it would only detect the lead in the paint. The front of the box even says "detects lead on any surface". Looks like its really made for painters.
