We uncover that Craft &amp Style pupils frequently have difficulty remembering the sequence of operations involved when producing a basic screwdriver deal with. These photographs depict this method.

We begin with the preparation of the 25mm aluminium blank. After this the blank is held in the 3 jaw self centering chuck. A series of turning operations is then carried out. For the following we set a high spindle speed and utilised a slow feed speed for greatest outcomes. 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 used to judge this.

Taps and dies are utilized to reduce the internal thread on the screwdriver blade and the internal thread on the handle.

Lastly each components are assembled and the handle is knurled or provided a textured grip pattern. This is done at a very low spindle speed and a slow automatic feed speed.
