Man, I just can't say it enough, I love to cut things with an angle grinder. Even if it is through solid as a rock, ultra strong, corrosion resistant cast-able with a really old crappy blade. Well I guess I wasn't exactly thrilled, but it wasn't too bad.
We are still working on the furnace, a new door and cap got cast last night. So after just a couple more things get changed we will be ready to stuff the top with fiber and MICROTHERM!!!
We are going to save that for a weekend evening.
