Though I have treated thus much on the Forging of Punches, yet must
all what I have said be understood only for great Bodied _Punches_;
_viz._ from the _Great-Primer_, and upwards. But for smaller Bodies;
as _English_, and downwards, the _Letter-Cutter_ generally, both for
_Romans_ and _Italicks_, gets so many square Rods of Steel, Forged out
of about two or three Foot in Length, as may serve his purpose; which
Rods he elects as near his Body and Sizes as his Judgment will serve
him to do; and with the edge of a Half-round File, or a Cold-Chissel,
cuts them into so many Lengths as he wants _Punches_. Nay, many of
these Rods may serve for some of the small Letters in some of the
greater Bodies; and also, for many of their _Counter-Punches_.
Having thus prepared your _Punches_, you must Neal them, as I shewed in
_Numb._ 3. _Vol._ I.
¶. 2. _Of_ Counter-Punches.
The _Counter-Punches_ for great Letters are to be Forged as the
_Letter-Punches_; but for the smaller Letters, they may be cut out of
Rods of Steel, as aforesaid. They must also be well Neal’d, as the
_Punches_. Then must one of the ends be Filed away on the outside the
Shank, to the exact shape of the inside of the Letter you intend to
Cut. For Example, If it be _A_ you would Cut; This _Counter-Punch_ is
easie to make, because it is a Triangle; and by measuring the Inside
of the Angle of _A_ in the Draft of Letters, as you were taught, §.
12. ¶. 6. you may make on your Standing _Gage-Plate_ a _Gage_ for that
Angle: So that, let the Letter to be Cut be of what Body you will, from
the least, to the biggest Body, you have a Standing _Gage_ for this
_Counter-Punch_, so oft as you may have occasion to Cut A.
The _Counter-Punch_ of _A_ ought to be Forged Triangularly, especially
towards the Punching End, and Tryed by the _A Gage_, as you were
taught to use the Square, _Numb._ 3. _Vol._ I. Yet, for this and other
Triangular _Punches_, I commonly reserve my worn-out three square
Files, and make my _Counter-Punch_ of a piece of one of them that best
fits the Body I am to Cut.
Having by your _A-Gage_ fitted the Top-Angle and the Sides of this
_Counter-Punch_, you must adjust its Heighth by one of the three
_Face-Gages_ mentioned in §. 12. ¶. 5. _viz._ by the Ascending
_Face-Gage_; for _A_ is an Ascending Letter. By Adjusting, I do not
mean, you must make the _Counter-Punch_ so high, as the Depth of the
Ascending _Face-Gage_; because in this Letter here is to be considered
the Top and the Footing, which strictly, as by the large Draft of _A_,
make both together five sixth Parts of a thin Space: Therefore five
sixth Parts must be abated in the Heighth of your _Counter-Punch_, and
it must be but four thin Spaces, and one sixth part of a thin Space
high, because the Top above the _Counter-Punch_, and the Footing below,
makes five sixth Parts of a thin Space, as aforesaid.
