ject of this will soon be apparent.
When the inner surface of the back plate has absorbed sufficient
moisture from the wet cloth, this being so in the judgment of the
operator, the wood will have lost very much of its resisting power to
twisting by the hands. Advantage is taken of this condition, and each
piece or collar of wood passed over the proper portion of the back like
a loop. If fitting tolerably close, all the better; but it may require
a soft wedge or two in parts to keep it from shifting after being placed
in position. In some instances more than two or even three or four
pieces may be of advantage where the tendency to twist is irregular.
The operator now gets a short plank of ordinary wood, of even surface,
straight, and true as possible in each direction; lifting the violin
table with the loops of wood attached and placing it on the plank, some
of the loops will be raised up on one side while others are depressed
at the same. In the case of the simple warp, one of the two will vary
in rise or a different angle to the plane. The process now is simple,
and the loop rising at one side will be pressed down and held in position
by either a weight or any contrivance handy. It should be done a little
more than seems necessary for restoring the even line of the edging,
which can be fairly well seen by looking along from end to end; this
is to allow of a slight recoil when the loops or wooden cramps are
removed.
For a more determined twist the extra depression of one part can be
accomplished by inserting layers of wood under the opposing parts so
as to get more distance for the remaining one.
Nothing is now required but the drying thoroughly. This will be
according to temperature and moisture present in the atmosphere; no
artificial means should be resorted to.
Not the slightest injury will accrue from the process described,
provided due care is taken that there is no overstraining, and the
damping is neither excessive nor insufficient. The result of the former
is likely to be an inequality in the bending, the line or level of the
edging when looked at along its course, will look uneven, as if some
upheaval had taken place here and there. Courage and caution are
faculties brought to bear strongly and continuously on the subject by
every repairer with a reputation for success. Without the former, many
attempts which might have ended successfully have proved to be failures
and to require doing over again; and i
