THE Pole is commonly made of a Fir-pole, and is longer or shorter, or bigger or smaller, ac∣cording to the weight of the Work the Workman designs to Turn: For the thicker the Pole is, the har∣der must the Tread be to bring it down; and for this reason, if the Pole prove too strong for their common or continued Work, they will weaken it by cutting away (with a Draw-knife, described Numb. 7. Plate 8. E, and § 5.) part of the substance off the upper and under sides of the Pole.
The thick end of this Pole is nailed (or indeed ra∣ther pinned) up to some Girder, or other Timber in the Ceiling of the Room, with one single Nail, or a Pin, that the Pole may move upon that Nail, or Pin, as on a Center, and its thin end pass from one Puppet to the other, as the Work may require. And at about a Foot distance or more, is also nailed up to some Joysts, or o∣ther Timbers of the Ceiling, two Cheeks of a convenient strength, and at the lower end of these two Cheeks is nailed a Quarter or Batten to bear the Pole, though the weight of a Tread be added to it, as you may see at n n in Plate 12.
