I have one of those old buzz saws, last time I used it was 1991.
It sits out in the yard and tourists ask me about it all the time. I have often thought about fireing it up just for a demenstration but then remember how afraid of that thing I really am. They more dangerous than a whole tree log chipper.

I burn between 6 and 10 cord of birch a year with an indoor wood boiler. House and shop are attached 30 X 80 ft with in floor heat. Got a propane boiler too so the amount of wood I burn is directly proportional to how I feel about chopping wood today.
