I can't wait to see what's next....

I remember reading an old Hot Rod Magazine that had an
article on a two-man small block Chevy powered chainsaw
and a one-man chainsaw powered by a Harley-Davidson
engine.


Should have seen "Mega machines" (or one of those such
titles) on the History channel the other night (last week?).
They had a chainsaw-like design that was designed for
trenching solid rock. The "chain" looked like a tank track
and they powered it with 1500 horsepower (3000?) - they
had a second 300 hp engine just to run the tracks for
moving it and running the hydraulics. Seems to me it could
cut a trench 20+ feet deep in solid rock - they used it for
laying pipes etc in areas where it was rock. Maybe it was
on the Discovery channel. The thing was HUGE and had
this giant "chain" with carbide tips that just munched through
solid rock. They said you can feel the ground vibrate
quite a distance away from this when it is running.
