Fig. 4-Chuck
Care must be taken to get the tailstock center vertically over the bed, else taper turning will result. To do this, a straight line should be scratched on the top of the bed pipe, and when the tail stock is set exactly vertical, a corresponding line made on this. This will save a great deal of time and trouble and possibly some errors.
The two designs of chucks shown in Figs. 3 and 4 are very easy to make, and will answer for a great variety of work.
As the details are clearly shown and the general dimensions given on the accompanying sketches, it should not be a difficult matter for the young mechanic to construct this machine.

Holder for Flexible Lamp-Cord
Ceiling-Cord Holder
The holder is made of a round stick—a piece of a broom handle will do—as shown in Fig. 1. It is about 1 in. long with two notches cut out for the strands of the cord. These holders are easily made and will answer the purpose almost as well as the ones made in porcelain. Painting or enameling will improve not only their appearance, but also their insulating properties. Several of them can be used along a line, as shown in Fig. 2.
