Having thus finisht his _Counter-Punch_, he Hardens and Tempers it, as
was taught _Numb._ 3. _fol._ 57, 58. _Vol._ I. And having also Filed
the Face of his Punch he intends to cut his _A_ upon, pretty Flat by
guess, he Screws the Punch upright, and hard into the Vice: And setting
the Face of his _Counter-Punch_ as exactly as he can, on the middle of
the Face of his Punch, he, with an Hammer suitable to the Size of his
_Counter-Punch_, strikes upon the end of the _Counter-Punch_ till he
have driven the Face of it about two Thin Spaces deep into the Face of
the Punch. So shall the _Counter-Punch_ have done its Office.
But if the Letter to be _Counter-Puncht_ be large, as _Great-Primmer_,
or upwards, I take a good high Blood-red Heat of it, and Screw it
quickly into the Vice; And having my _Counter-Punch_ Hard, not
Temper’d, because the Heat of the Punch softens it too fast: And also
having before-hand the _Counter-Punch_ Screwed into the _Hand-Vice_
with its Shank along the Chaps, I place the Face of the _Counter-Punch_
as before, on the middle of the Face of the Punch, and with an Hammer
drive it in, as before.
Taking the Punch out of the Vice, he goes about to Flat and Smoothen
the Face in earnest; for it had been to no purpose to Flat and Smoothen
it exactly before, because the Sinking of the _Counter-Punch_ into it,
would have put it out of Flat again.
But before he Flats and Smoothens the Face of the Punch, He Files by
guess the superfluous Steel away about the Face of the Letter, _viz._
so much, or near so much, as is not to be used when he comes to finish
up the Letter, as in this present Letter _A_, which standing upon a
Square Face on the Punch, meets in an Angle at the Top of the Letter.
Therefore the Sides of that Square must be Filed away to an Angle at
the Top of the Face of the Punch. But great care must be taken, that
he Files not more away than he should: For he considers that the left
hand Stroak of _A_ is a Fat Stroak, and that both the left-hand and
the right-hand Stroak too, have Footings, which he is careful to leave
Steel enough in their proper places for.
The reason why these are now Fil’d thus away, and not after the Letter
is finisht, is, Because in the Flatting the Face there is now a less
Body of Steel to File away, than if the whole Face of the Punch had
remain’d intire: For though the following ways are quick ways to
Flatten the Face, yet considering how tenderly you go to Work, and with
what Smooth Files this Work must be done, the riddance made will be far
less when a broad Face of _Steel_ is to be Flatned, than when only so
much, or very little more than the Face of the _Letter_ only is to be
Flatned.
