I have been putting the setting on 3 and a half to 4. It goes much higher. And with a non heated garage pouring at around 45 degrees could be a culprit as well. I always let the lead melt for a good 30 minutes with the mold on the pot while it is melting. The other thing could be is that even though the mold is hot the hooks may not be hot enough when I pour. So I will turn the heat on the pot way up to see if that helps. I will tinker a bit to see what works and pass on my findings. I appreciate everyones feedback. I think I've found something to help pass my time! I work graveyard, so basically on my days off I keep the schedule. So when I'm not working overtime the night gets long just setting on the dang sofa! lol
