Remember that movie "Airplane"? A woman on there got hysterical and a line formed in front of her waiting to beat the crap out of her? People had sticks, wrenches, bats...
I've got an idea. I remember, Dennis I believe, saying he fixed up a saw that looked like it had cut thru his head for halloween one time. Now, that's what I'm talking about... not dorky at all. :alien:
chainsaw mills are more portable than the mill you described. Probably safer too. But if you were going to set up a semi stationary mill a car motor or old tractor would make sense.
Don't know if Baileys still has these saws or not. They display a Polulan Pro behind their counter along with their b-series saws.
