You may in other places, where you find most Convenience (as at i) make a Square, which may stand you in stead for the Squaring the Face and Stems of the Punch in Roman Letters, and also in many other Uses.
And you may make Gages, as you were taught before to try the Counter-Punches of Angular Letters; as, A K M N V X Y Z, Romans and Italicks, Capitals and Lower-Case. But then, that you may know each distinct Gage, you may engrave on the several respective Gages, at the Angle, A A 4 &c. For by examining by the Drafts of Letters, what Angle their Insides make, you may set that Angle off, and make the Gage as you were taught before, in the Gage for the Slope of Italicks.
¶. 7. Of the Liner.
The Liner is marked E in Plate 10. It is a thin Plate of Iron or Brass, whose Draft is sufficient to express the Shape. The Use of it is on the under-edge a b (which is about three Inches long) and is made truly straight, and pretty sharp or fine; that being applied to the Face of a Punch, or other piece of Work, it may shew whether it be straight or no.
¶. 8. Of the Flat-Table.
The Flat-Table at F in Plate 10. The Figure is there sufficient. All its Use is the Table F, for that is about one Inch and an half square, and on its Superficies exactly straight and flat. It is made of Iron or Brass, but Brass most proper. Its Use is to try if the Shank of a Punch be exactly Perpendicular to its Face, when the Face is set upon the Table; for if the Shank stand then directly upright to the Face of the Table, and lean not to any side of it, it is concluded to be perpendicular.
It hath several other Uses, which, when we come to Casting of Letters, and Justifying of Matrices, shall be shewn.
¶. 9. Of the Tach.
The Tach is a piece of Hard Wood, (Box is very good) about three Inches broad, six Inches long, and three quarters of an Inch thick. About half its Length is fastned firm down upon the Work-Bench, and its other half projects over the hither Edge of it. It hath three or four Angular Notches on its Fore-end to rest and hold the Shank of a Punch steady when the End of the Punch is screwed in the Hand-Vice, and the Hand-Vice held in the left hand, while the Workman Files or Graves on it with his Right Hand.
Instead of Fastning the Tach to the Bench, I Saw a square piece out of the further half of the Tach, that it may not be too wide for the Chaps of the Vice to take and screw that narrow End into the Chaps of the Vice, because it should be less cumbersome to my Work-Bench.
