Been chilly of late in W. Indiana!
In one part of my mettle pole barn I sectioned off a room in Sept for my little shop. I insulated heavy, then put up some old 1x12 oak boards I had scavenged from another barn. Then I put in a BIG woodstove,
Our local sawmill has a huge pile of cutoffs almost all of which will fit in the stove, all various hardwoods! I can get all I want... FREE pick up at least a truckload every week. (scroll it, turn it, or burn it) It all gets used.
The night before I plan on being in the shop, I fill the stove with wood at night, My son builds me a fire with a little diesel when he feeds the chickens & Rabbits in the morning before school.
By 9:00 my shop is 60-70 while its 10-15 outside...
Life is good!
