But we will suppose now the _Body_ somewhat too big, and that it drives out at the _Head_ or _Foot_; and that the thickness _drives out_ at the _Head_ or _Foot_ and that the Sides of the _Body_ are not straight. These are Faults enough to take the _Mold_ asunder: but yet if there were but one of these Faults it must be taken asunder for that; by unscrewing the _Male-Gage_, to take the _Body off_ the _Carriage_, and the _Carriage_ off the _Bottom-Plate_. Having found where the Fault of one or both sides of the _Body_ is, he lays the _Body_ down upon the _Using-File_; and if the Fault be extuberant, he rubs the Extuberancy down, by pressing his Finger or Fingers hard upon the opposite side of the Body, just over the extuberant part; and so rubbing the Body hard forwards on the _Using-File_, and drawing it lightly backwards, he rubs till he has wrought down the extuberancy, which he examins by applying the _Lyner_ to that side of the Body, and holding it so up between his Eye and the Light, tries whether or not the _Lyner_ ride upon the part that was extuberant; which if it do, the extuberancy is not sufficiently rub’d off, and the former Process must again begin and be continued till the extuberancy be rub’d off. And if the Body were too big, he by this Operation works it down: Because the extuberancy of the _Body_ rid upon the _Carriage_, and bore it up. And if the fault be a _Dawk_, or Hollow in the _Body_, then he Works the rest of that side of the _Body_ down to the bottom of the _Dawk_, which by applying the _Lyner_ (as afore) he tryes, and this also lessens the _Body_. If the _Body_ drive-out at _Head_ or _Foot_, he lays the weight of his Fingers heavy at that side or end of the _Body_ which is too thick, and so rubs that down harder. If the thickness of the Letter, drive-out at _Head_, or _Foot_, he Screws the _Body_ into the _Vice_, and with a flat sharp _File_, files the _Side_ down at the _Head_, or _Foot_. At the same time, if the _Shanck_ of the Letter be not Square, he mends that also, and smooth-files it very well. Then he puts the _Mold_ together again: And melting, (or laying aside) his first _Proofs_, lest they should make him mistake, he again _Casts_ about twenty New _Proofs_, and examins by them as before, how well he has mended the _Body_, and how near he has brought the _Body_ to the size of the _Pattern_: For he does not expect to do it the _First_, _Second_, or _Seventh_ time; but mends on, on, on, by a little at a time, till at last it is so finisht. If the _Body_ prove too small, it is underlaid with a thick or a thin _Asidue_; or sometimes a thin _Plate_ of _Brass_. Then he examins the _Mouth-piece_, and sees that the _Jaws_ slide exactly true, upon every part of the _Pallat_ without riding. If the _Throat_ of the _Mouth-piece_ lie too low, as most commonly it is designed so to do; Then a _Plate_ of _Brass_ of a proper thickness is laid under it to raise it higher.
