HOW TO MAKE A HAND-WINDER. iffVF the different objects that can be made at the lathe, we shall take special care to speak of DEGREES DEGREES those that will both interest and afford experience to the turner. We are now about to describe the way to manufacture a Hand-winder (fig. 1, Plate XVII.). As the manufacture of this article includes the art of the carpenter as well as that of the turner, it will give the beginner an opportunity of practising the handicrafts connected with that with which we are more especially concerned. We shall name no particular wood, the reader may select that for which he has a preference. He should take a sound piece of wood, 7 or 8 inches square, and a good inch in thickness. This must be carefully planed on both sides till its thickness is uniform. A hole of from f to -?6 of an inch in diameter must now be made in it with spoon-bits of gradually increasing size, and this must be bored out with a screW-tap cutting a thread about g of an inch in diameter. We shall presently explain the screw-tap and the way to use it. Now turn between the centres a cylinder about of an inch in diameter, and from 6 to 7 inches in length, but keep a much thicker part, of from I to $$ of an inch diameter, at the end of the cylinder, such as is represented in fig. 10, Plate XVI. If the thread made by the screw-tap is exactly perpendicular to the wood, it ought to fit closely against the thick part of the cylinder, and when placed between the centres on the cylinder, it ought to turn truly. The workman should now, with a gouge, make a circular moulding half the thickness of the block of wood, which we shall henceforth call the Foot of the Winder, and the profile of which is represented in fig. 11; or if he prefers it quite round,
