[TheForge] Brainstorming -- Trouble with trees (OT)

Sat Feb 6 00:46:44 EST 2016

Might possibly work, Bruce, but my thought about it not being tried
previously is because rock and PVC pipe are pretty hard- trees are a lot
softer. I remember my g'mother's boyfriend, who  was into geology, showing
me that a rock saw would cut just fine through the geodes he was cutting
up, but I could put my hand on the blade, and it just tickled a little bit.
I suspect the hardness of the material might have a lot to do with how
various types of implements cut it. However:

Now, whether it would be safer of economically feasible for volume wood
cutting is another question.

Saint Phlip

Only President Obama could double the stock market, cut the deficit by
2/3, bring
gas down under $3, get bin Laden, end 2 wars, bring unemployment down under
6%,  while fighting a government that is trying to destroy him, and still
be told he's failing as President.

Heat it up
Hit it hard
Repent as necessary.

Priorities:

It's the smith who makes the tools, not the tools which make the smith.

have read with pleasure. -Clarence Darrow
