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

[jerry Frost]

Sometime in the early '80s I was visiting the Folks in Portola Ca. A friend
and I hit the Ponderosa Ranch. On display was a 17hp steam traction engine
that pulled a land train from St. Louis IIRC pre-civil war. Anyway, being
steam powered it burned wood, lots of wood. 

As part of the display was the chain saw. The chain was your basic tie down
type with triangular points welded in the center of each link. There was a
sprocket that could be mounted on several PTO points. The chain was hauled
around the target tree and reconnected in a loop. The traction engine backed
up till the chain was tight and the pto engaged. The chain simply fed like
the chain on a bicycle and it sawed through the tree.

Once felled it was skidded back to the engine, bucked with the onboard
circle saw and loaded in the tender.

It's been a few years since this thread, but I just got another idea.  I
just watched a YouTube video of a guy sawing through PVC pipe using nothing
but string.  Of course, that's plastic, not wood, but ROCK can be sawn with
a mudsaw which is nothing more than a flexible wire carrying grit.

So, why not a mudsaw for trees?  Imagine a wire wrapped halfway (or maybe
once and a half?) around a tree (or tree limb), each end of which is
connected to a reciprocating pulley.  I'm envisioning the wire moving at
least several tree diameters in each direction before reversing direction.
Alternatively, the wire could run continuously in one direction -- whichever
is easier to implement.  I suggest the former because the latter requires a
full loop of wire, and that might be more difficult to get around a tree.

Now to work, the wire needs to be carry grit. We also don't want to be
nearby if the wire breaks (under tension).  Solve both problems by using
semi-rigid tubing around the wire.  The tubing acts as a safety if the wire
snaps. It also can be used to transport grit to the wire, which the wire
carries to the tree, just like a mudsaw for rock.

I'm envisioning the mud to be like toothpaste with coarser grit.  Maybe 100
grit -- I don't know.  Suspend the grit in something non-polluting, like
soap softened to toothpaste consistency.

A variation on this might be to use a common chain (not a chainsaw chain)
instead of a wire.  Possibly it would be easier to power a chain, but a
mudsaw doesn't work by power but by patience, so that might not matter.

Why bother with all this?  Because you could operate this thing remotely
from the tree.  It's low tech and possibly safer than other common methods.


Any thoughts?
