What is an Up-Cut saw, how does it operate (I have a 1980 Rockwell
Uni-saw, is it similar?), is an up-cut saw used similarly as a regular
table saw, is a left hand up-cut saw preferred and why (as opposed to
right hand, if such exists)?
Item: Whirlpool 1000 Left Hand Pneu. Up-cut saw (serial # 151839), 14"
blade, 7.5 hp motor (3 ph), with 96" roller table. I suppose the motor
can be changed for 220 usage. I don't know the age of this saw, but I
suspect not more than 20 yrs old.
Is $200 to $300 for this saw, in working order, a reasonable deal?
There are 3 of these saws available. Or should I pass on this? I
have until Dec 27th to decide.
I believe that that is a "Whirlwind" not "Whirlpool" and if you google
that name (i.e. "Whirlwind saw") you'll find a bit of information about
them. Other than that and that it's a $4000 saw I don't know anything
about them other than what I find in that search.
According to that web-page this is an industrial cutoff saw. To me it
would be worthless unless you are doing massive amounts of relatively
small width cut-offs (i.e. building manufactured housing or
something). Apparently the blade is below the table. You position the
material and activate a pneumatic clamp to hold it then step on a
floor mounted switch and the blade is brought up through the material
producing the cut-off and then the blade goes back below the table,
the clamp is released and you position the next piece of material -
rinse & repeat.
I've seen one of these in operation in NC. A fellow has a shop that does
nothing but cut shelf-width sections out of larger sheets of MDF.
The "Wow factor" is significant but the owner/operator would agree that its
not a general purpose tool nor the most accurate device available.
It appears that the benefit includes the fact that the "disappearing blade"
allows a free flat table surface between cuts making removal of cutoffs and
re-aligning stock a bit safer for the operator and helper(s) intent upon
sawing as many pieces as possible in the shortest period.
A company local to me makes them (Lauderdale-Hamilton, Shannon, MS).
His version of an up-cut saw is a large blade chop saw, where the
blade rises through the table. He also makes gang rip saws and other
types of machines for the industrial woodworking industry.
$2-300 for one of his saws would be a steal.
If it actually works, that's $0.10 on the $$, so it would be a good
value. But, unless you're going to try to resell it or have a need, if
you don't know what it is, you undoubtedly don't have a use for it. :)
These are _production_ machines, designed for one specific purpose and
are of no use (and can't be used) for anything else -- they're a cutoff
saw for rapid, repetitive cutting of material to length. That's, it.
To use it, you'll need 3-phase power and probably 408/440 at that. I'd
have no illusion the motor is convertible to lower voltage (altho
there's an outside chance it might be, I'd figure it minimal at best).
On top of that, you'll have to have an industrial-sized supply of
compressed air as they use pneumatic hold downs which are required, not
optional, in order for the machine to operate. They are somewhat like
a radial saw, except the blade is underneath the table and comes up
(hence the name) and does not slide on an arm but simply rotates up to
cut the material placed over it.
So, unless you're planning on going into the furniture or
cabinet-making business in a big way, or simply want to see if you can
maybe make a buck, I'd say you don't want one of these...
OBTW, it's Whirlwind that is the manufacturer, not Whirlpool...I didn't
look, I suspect they have a web site although they're not set up for
individuals/home shop-type users, so I don't know what they might have
