Chuck a finish nail (brad) in a drill. The end of the nail will be sheared off, not conical, so it will act as a reamer. You will most likely have to go through both sided. A jig eye buster will be harmless to the powder coat, don't bother.I bet you wont make the same mistake again!
Need to use a fluid bed for better technique with those smaller jigs. It'll keep the eyes from plugging to start. Only way to clean them once cured is with a heated probe. Straightened hook, needle, etc.. I use a larger jig cut off and sharpened. The head becomes a handle. Really no need to cure those little jigs. Phone a friend.
Here's another time-saver: Just use a candle or a Bic lighter to heat up the jig, dip in the powder, tap off the excess powder, then heat again and you're all done, no oven to mess with!
Plumbers torch (propane), works like a charm...
Yeah, a Westinghouse J-34 would do the trick too, but that's a bit of overkill when all you need is about 200 deg. of heat on a little jig head.
