In part 1 of
this series, I described the basic hand tools used for clearing and
treating timber so that items could be produced to enhance life. Part
2 continues in this vein, but this time I am describing the more advanced
tools (medieval power tools!) used for the preparation of the timber
which, in a workshop as far back as the pre-Roman Celts would be fairly
commonplace. These items would still have been seen in everyday use
as recently as the start of the industrial revolution where more "mechanical"
devices were conceived. Even today the basic principles used by these
tools are relatively unchanged apart from the materials used to build
them and the power source used to drive them.
The Tining
Stool
A
Tining Stool is basically a length of timber on legs that can seat a
man at one end. the other (working) end has a hole in the timber often
either lined or surrounded by an iron ring, or former.
Short lengths
of wood roughly squared are placed onto the former and then hammered
through to produce a regular size of peg or "nail" (the original nails
were all made of wood). Different formers could produce different widths
and shapes of peg. Once these were produced in quantities they were
then used in the construction of buildings. Rake tines (where the name
for the stool originated) which are the "teeth" of the rake and any
number of other items that required pegs, nails, dowels etc. This made
the building trade of the time more efficient by the use of quick mass
production.
The Shaving
Horse
The
Shaving Horse was a very similar contraption to the tining stool in
that it was based on the exact same "table" base. In fact the one stool
could do either job just by replacing the actual tooling section.
The timber support
is mounted on a long bar that holds a cross beam above the table with
a foot pedal structure below. This whole unit pivoted on a peg mounted
through the horizontal plane of the table.
To shave timber
all that the operator was required to do was to place his timber on
the table at one end and raise the section for shaving either by resting
it on his chest or knee. The wood was firmly held in place by putting
pressure on the foot pedal which forced the cross beam to lock the timber
in position while a draw knife (see part 1 in FLAME 4) was pulled along
it. This allowed for very straight batten shaving and could also be
used to produce circular dowels (after a little practice) which are
straighter than present day machined versions.
The Pole Lathe
The
pole lathe is the direct ancestor of the modern wood and metal turning
lathe, and over the centuries very little has changed indeed!
The pole lathe
is used for turning wood at high speed for shaping into chair and table
legs, for producing bowls and plates, mugs and cups, and any other job
that required large circular or scalloped shaping. Historical records
show that the pole lathe was the preferred tool for creating well known
furniture such as the original Windsor chairs in the 13th century. Also
famous 17th and 18th century cabinet makers also specified its use over
the more recent designs for "accuracy" reasons and examples of these
can be seen in the designs by makers such as Chippendale, Hepplewhite
and even Robert Adams during the Neo-Classical era.
The pole lathe
is operated quite simply with a long pole hung on a tree fork and strung
to the tree. This creates a spring effect and the tip of this is attached
around the piece being turned by a rope and then onto a foot pedal that
is pumped up and down again to turn the piece being worked on.
In part 3 I
shall be demonstrating how to build simple camp furniture to make life
a little more comfortable during those long sessions around the camp
fire.
