The Simple Operation of a Peterson Portable Sawmill
-
A single circular
blade swings 90' to achieve first a horizontal, then a vertical
cut, in order to free a perfectly dimensioned piece of timber from
the log. A rise and fall mechanism is mounted within a carriage
which is manually pushed and pulled upon parallel tracks over a
stationary log.
-
To start a log,
the blade unit is positioned at the top left of the log, with the
blade in horizontal position. The operator gently pushes the mill
frame gently through the log to effect the first cut - see below.
Carriage movement through the log only requires about 10lb of pressure,
as you are letting the blade do the work. The mill is pushed into
the log with blade in horizontal position.
-
At the other
end of the log, the operator then pivots the blade to vertical position.
On the Production Frame, the handle is unlocked with a gentle outward
tap of the palm, and the blade pivot itself is aided by a powerful
spring.
-
Due to the originality
of the design, no special locking mechanisms are required, making
the entire process quick and simple - many of our customers comment
on how easy it is to use in comparison to other brands! The operator
now pulls the unit back through the log in vertical position to
complete a cut - see below. Your dimensional board is now free for
removal, and fully edged!
-
After swinging
the blade to vertical, the unit is pulled backthrough the log to
completely free a dimensional board
-
The blade unit
is now moved right, to the desired width of your next board, and
the horizontal and vertical cuts are repeated in the above order.
-
Once a whole
row of cuts across the log face has been completed, the blade unit
is returned to the left of the log, and the entire bed unit is then
LOWERED to the desired depth of your next row of cuts. On the Production
Frame, an easy 5:1 ratio winch is mounted near the sizing dial for
quick setting and lowering. Lowering the blade unit using the simple
hand-winch, for your next layer of cuts.
-
Basically, these
steps are repeated until you have only a thin firewood slab remaining
at the bottom of your log - you have no need to move the log at
any time during the whole sawing process. The concept is extremely
inventive, but surprisingly simple. Running a single blade instead
of two at once, also means you do not need a huge motor, which of
course decreases both overall cost AND weight!
