We find that Craft & Design and style pupils frequently have difficulty remembering the sequence of operations involved when producing a straightforward screwdriver deal with. These photographs depict this process.
We begin with the preparation of the 25mm aluminium blank. After this the blank is held in the three jaw self centering chuck. A series of turning operations is then carried out. For the following we set a higher spindle speed and utilised a slow feed speed for greatest benefits. Shown right here we show facing off. Then turning down or parallel turning. Next taper turning. Following that the Slocombe bit or centre bit is mounted in a Jacob’s chuck and a pilot hole is drilled. A HSS twist drill or jobber bit is then mounted in the Jacob’s chuck and a blind hole is drilled to a depth of 30mm. The depth gauge is employed to judge this.
Taps and dies are used to cut the internal thread on the screwdriver blade and the internal thread on the deal with.
Ultimately both components are assembled and the manage is knurled or provided a textured grip pattern. This is completed at a extremely low spindle speed and a slow automatic feed speed.

How a ball pc mouse functions
Image by explainthatstuff
Here’s a closeup of the mechanism that permits an old-style ball mouse to detect your hand movements. There’s a light beam operating among the transparent square (an LED-style light emitter) and the black square (a photocell/light detector). As you move your hand, the mouse ball moves too. It pushes against a roller that turns the spoked wheel, breaking the light beam repeatedly. Counting the quantity of occasions the beam is broken provides a precise measurement of how far your hand has moved.
