In order to help, I've taken a whack at heating the barn. We have a standard kerosene heater that should be plenty. But unless you're standing right next to it, it doesn't do much good. It's about as useful as a candle right now. It's not radiating or convecting, or making it any more comfortable to be out in the shop. And a cold press means that the plates won't stick to the aluminum base, which means we (kate) have (has) to bring the base inside to warm it up, then go back out and use it, and then bring it inside when it gets chilly again.
I've heard the word "motherfucker" around the house a lot lately.
I'm going to try nailing up some insulating panels between the studs.
