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?
