long. b b two Stiles placed towards either end, and fastned upright. In the hithermost Stile is a Coller described § 7. and Plate 13. H, or any of the other Collers: And in the further Stile is fitted a square flat tempered piece of Steel having a Center-hole in the middle of it, and is placed just against the Center or middle point of the Hole of the Coller. c c the Rowler, whose hither end is Turned away, so as it just fit into the Coller, and at the further end of it, it hath a tem∣per'd Steel Pin, to be placed in the Center-hole: And in the middle of the hither end of it, it hath a Piercer-Bit fastned straight in, so that it lie in a true straight Line, with the Axis of the Rowler. Of these Rowlers they have several, and Bits of different sizes fitted into them, that upon all occasions they may chuse one to fit their purpose.
On the under-side, about the middle of the Bench, is fitted and fastned athwart it a square Iron Coller, deep enough to reach through the Cheeks of the Lathe, and so much deeper as it may receive a Wooden Wedge, such a one as belongs to one of the Puppets: And by the force and strength of the Wedge, the whole Drill-bench is drawn down and fastned athwart the Cheeks of the Lathe.
When it is used, it stands athwart the Cheeks of the Lathe (as aforesaid) with the point or end of the Bit towards you; and then the String being turned twice or thrice about the Rowler, will (with Treading on the Treddle) turn the Rowler and its Bit forcibly about, and cause it to enter swiftly into a piece of Wood that shall be prest forwards upon the Bit.
When they use it, they hold the piece of Wood they intend to Drill, or Pierce, fast in both their Hands, right before them, and press it forwards upon the Piercer-Bit; so that by its running about, it cuts a straight round hole into the Wood, of what length they please.

But while the Pole is rising after every Tread, they press not against the Piercer-Bit, so that it is dis-ingaged from doing its Office in the Wood; but in that while, they nimbly give the Wood a turn in their hands, of a∣bout one third part of its Circumference; which makes the Bit very successive Tread, go the straighter through the middle of the Wood: And thus they reiterate Treads, and keep the Wood turning in their Hands, till the Bit is enter'd deep enough.
Thus much of the Tools used in common Turning: I shall proceed to the Working a Pattern or two in Soft Wood; which being well understood, may render a Practicer capable of most common Work.
