Use Little Effort to Wind Honeycomb Coil The satisfaction of proudly exhibiting the ordinary man's ability to make this or that as well or better than the "boughten article," is likely more pronounced in the Radio enthusiast than in any other hobby, and this article is to show how any kind of honeycomb coil may be made with very little trouble. First of all, determine the number of turns you want, as this matter is important in selecting the size of wire to be used. Number 24 single cotton covered is about right for small inductances, and Number 28 S. C. C. for large ones. If possible, secure a heavy cardboard box two inches in diameter and cut it into rings one inch across in the manner of a napkin ring. The start is made under auspicious circumstances. However, such a tube is not always at hand. Then take a piece of soft pine and work it down to a diameter of about 1% inches, cut some heavy wrapping paper into long strips, the width being about equal to the length of the round pine stick, and with wellstrained shellac coat one side of the paper, wrap it neatly around the stick until you have built up a tube of 2 inches diameter. Some oil or waxed paper wrapped around the stick before laying on the paper tube will greatly aid in slipping the coil off the tube when the winding is completed. After the tube is thoroughly dry, and has had another one or two coats of shellac, it is ready to cut into rings. Don't throw the stick away; it will be needed again. Cut about two inches off one end of the round piece of wood, drill a hole through the center of the small piece, and take a nail just a trifle larger than the drill hole and drive it through the drill hole up to the head, which will leave about an inch of the point of the nail protruding. Take the longer piece of round pine and set it on end and drive the nail into it, in the center, if you can, but this is a matter of little moment. This is your winding form. The nail is used to hold it in the vise, or if you have loaned that out, fasten it on the work bench. This allows one end to be revolved for your winding while the other end holds your work upright and in front of you. Take a strip of paper and measure around the stick, marking the exact diameter on this strip, and mark off 24 equal spaces on it, numbering each mark from 1 to 24, so that if there were a line number 25 it would just fall under the lap of number 1. Now, in a straight row all the way around the stick, drive a pin through the center of each mark, into the wood as far as you can drive it without its bending. If you bend a pin pull it out and dp better on the next one, as a bent pin will interfere with your winding. After one row of pins has been put around the stick, slip one of the rings over the end of your stick down to where the row of pins will stop it, and then drive another row of pins around the stick, each pin to be as close to the end of the ring as possible, so that the ring will not slip. Now, if you have the 24 spaces marked and numbered so that the numbers are visible to you, you are ready to begin winding. Put the end of the stick that holds the work in the vise, hold your spool of wire in one hand, with a few inches of wire sticking out, wrap it around the pins 9 and 10, thence to 21 and 22, going laterally across, then back again to and around 8 and 9, then over and across to 20 and 21, then to 7 and 8, 19 and 20, 6 and 7, and so on, until you have returned to where you started from, which in the few minutes you have been at work, gives you exactly 24 turns. At this point, especially if making a large number of windings, it would be well to make a tally sheet, so that if interrupted, you have not lost count. After the desired number of turns has been made, it is well to cut the wire a few inches away from the coil, secure the loose end with a weight, or get Willie to hold it, while you drop a small gob of hot sealing wax on it to hold it in place. Now, the coil is ready to apply a fixitive or coat of something to hold it rigid. Shellac can be used for this, putting on only enough to hold it in shape, but collodion is probably better for that purpose, and a couple of ounces will paint a good-sized coil, always remembering that collodion is very inflammable and will dry in a few minutes. After this is dry, remove one of the rows of pins and slip the completed coil off the form and mark the coil inside with the size wire, date, and more important, the number of turns. In starting your winding, especially a large coil, it is well to take a sheet of paper and map off each zigzag of your winding so you won't lose your place, as, for example, 9-10 to 21-22 8 9 to 20-21 • 7 8 to 19-20, etc, When you have reached 10-11 to 22-23, you are ready to go. The expense of constructing a multiple wire antenna may be reduced and its efficiency increased by placing one or two insulators in the rope connected to the bridle instead of inserting an insulator in each individual wire.
