he Bell into it, which
is called _Hanging of a Bell_, I shall speak something:
First, find out whether the Cannons be upright and true,
then raise the Bell up by some Rope tyed to the Cannons,
and so that the Bell hang level, which you may find, by
applying a Plumet to the brim, then fasten a string to the
Crown-staple within the Bell, then (a Plumet being tyed
to the other end of the string) if the string hang in the
midst between the two sides of the Bell whereon the Clapper
should strike, the Crown-staple is cast into the Bell true:
Now when you have hung the Bell, and let the Gudgeons in true
by Keys (for therein consists the main point of the going of
a Bell) then if the Clapper hang in the midst between the two
striking sides, and the Stock stand upright, the Bell is well
hung.
If a Bell have a longer stroke on the one side, than
the other, truss up that side which hath the short stroke
more, or let the other side down, and put a piece or two
of Leather in, according to the stroke; but sometimes the
fault of the stroke is in the Sally, which you may remedy,
by tying the Fillet (or little Cord about the rim of the
Wheel, which causeth the dancing of the Rope) nearer, or
farther off the main Spoke; nearer makes a short stroke,
farther off the Spoke, a long one.
And observe, that the trussing or taking up of a great Bell
far into the Stock by a notch, makes the Bell go easier,
and lie lighter at hand (that is) when it is set, for the
farther the brim of the Bell is from the centre of gravity,
the heavier it is: Now the centre of gravity is a supposed
line drawn through the Stock from one Gudgeon to the other;
but note, if you truss a Bell up, that the Crown-staple
be much above the Gudgeons, you must fasten a false Eye to
the Crown-staple, and to this false Eye hang the Clapper,
otherwise it will not strike so freely: Now small Bells
must be trussed up short, for else the Bell hanging low,
and fetching a great Compass in the swing, and having but
little Compass in the brim, the Clapper keeps along by the
side of the Bell, and gives no blow at all; but being hung
short, the Bell fetches a quick and short Compass, equal
to the bigness of the brim, and the Clapper strikes well.
Now for the tempering of the Gudgeons, I leave it to the
judgment of the Workman; but a word or two of the polishing
of it. After it is filed, or turned exactly round, take
two pieces of Oak, and oyl one side of each, and strew fine
