just pour a few without a thru wire and that will warm up mold and then just remelt them down again. Very simple. Just do out doors or with lots of ventilation. Use PAM on your thru wires so they pull out easy.

Didn't think of Pam.....good idea.
My thru wires are not actual through wires you'd use for plug making. I made a piece with 1/8" stainless rods press fit into a piece of aluminum. It slides up into the bottom of the U-Do-It mold. I'll try and take a picture tonight. Going to try it tonight.
One quick question......after I pour, how long do I wait before removing them? 2 mins, 5 mins, 15 mins? I imagine it solidifies quickly and the more I pour the hotter the mold gets....so I Imagine I would need to wait longer, the more I pour?
