[AT] PTO-driven table saw - Dang it !!!

Shifter fork! Shifter fork?  I thought the typical device for that
operation was a ball bat or an old shovel handle while the belt is
running.  All you have to do is to ease the belt on to the idler pulley
or the power pulley, and if the pulleys are crowned correctly the belt
will stay in the new location.

Of course you do have to be careful not to tear up the belt splice when
you're in the middle of the shift.  

I may not have been paying as close attention to the line shaft
operations as I could have, but I don't remember seeing shifter forks.
Shifter forks sounds like a Cadillac of operations.  

In thinking about this, I'm going to make a mental note to look for
shifter forks this summer at Portersville.  The Portersville,
Pennsylvania, show is a small event at a club-owned show grounds that is
devoted to steam.  They have a boiler fired up behind the grandstand
with better than a dozen steam machines hooked to it, and they have a
complete and functioning steam-powered machine shop with everything
connected by line shafts.  They also have a stationary engine shed with
a number of big hit-miss engines permanently on display and in operating
condition.  And, they have old tractors, a requisite flea market, Civil
War demos (not a reenactment), and a number of other displays similar to
Conner Prairie.

	Yeah, I consider it a jointer. Some folks call them a jointer /
planer. I was looking at 
the belt pullies trying to decide if it was built as a driving pully or
if it was planned 
to power another tool from the same drive. It used to be common to do
that. I noticed 
that it was a drive and idler set but didn't notice a shifter fork. It
might just be two 
drive pullies set together to handle a wider belt.
	The fence that is sitting now like for the saw (I would call it
an edger) is also the 
jointer fence and looks like it could also serve as a mount for a tool
rest for the 
grinder.
	It should make a very busy looking demonstration along next to
my buzzsaw and a big pile 
of slabwood. Like the buzz saw it also looks like a very good place for
a great deal of 
caution.   :-)   and maybe a few homemade guards.

	Mattias, I doubt it would float well...   ;-)

	Maybe that pully could be used to drive an air conditioner and a
refrigerator.   ;-)
