These are all welded joints.
1. Cut off six pieces of rod the length required, also two short pieces, and tie together with iron binding wire as shown in No. 1.
2. Weld the ends together at the top and bottom as No. 2, holding them in the hollow bit tongs.
3. Upset and scarf a piece of 7/16 in. round, scarf one end of the handle and weld together. This gives you something to hold it by.
4. Shut a collar on top and bottom as drawn in No. 3.
5. Heat the end to a welding heat and form the knob as in No. 4, then slightly round up bottom collar.
6. Heat evenly in the required place (see No. 5) and carefully twist it. The heating is important, or it will not twist evenly.
7. Carefully heat and unwind slowly, slightly tapping the knob, thus shortening the handle a little.
8. Regulate the cage so formed with flat and round-nosed pliers.
9. Shape bottom collar with half-round files.
10. Clean up with files and emery cloth, seeing that the wires are kept circular.
The handle itself is decorative, but it could be enriched by shaping the knob or engraving it. The handle need not be made from round wire, but it could be made from 3/16 in. square that has been twisted in opposite directions, so that as there are six wires you could have one twisted to the right and the next to the left and so on. When finished three wires would have a very gradual or slow twist.
This is the welding; and the ball knob should be done with a hammer, not filed. It is a good test for the appreciation of line and form, as a templet or guide is not used.
