Making a Spoke Tenoning Machine
A good spoke-tenoning machine can be made as follows:
Fig. 166 represents the machine completed. Fig. 167 represents the movable joint with set screw, as shown at m m, in Fig. 166. This device enables the operator to raise or lower the machine to suit hubs of every length. Fig. 168 is one of the rests with wooden boxes for the shaft, as shown in Fig. 166 at f f. This rest should be ten inches high.
Fig. 169 is the feed lever, which should be twenty inches long, and have a steel fork at one end to fit over the shaft, as shown at e, in Fig. 166. The lever should be made from flat iron, one-quarter by one-quarter inch, and have a hole punched in it, as shown in Fig. 169, to connect it to the piece shown in Fig. 171, and also in Fig. 166 at i.
The springs should be closed at e, so that the lever will not drop off the shaft. Figs. 170 and 171 represent pieces which connect the lever with the bench, as shown at i and j, in Fig. 166. The piece shown in Fig. 171 is connected by means of a rivet with the piece shown in Fig. 170, and the latter is bolted to the bench. Fig. 172 represents the shaft. It has a solid collar where the lever connects with it, and it also has a common brace chuck to hold the auger. This shaft should be three-quarters by twenty-four inches long.
In Fig. 166 a is the wheel stand, screwed to the floor, and b is the bottom platform, two by twenty-one inches by thirty-six inches, c c are braces to keep the auger level with the bench, d is the lever, e is the solid collar with the fork in position. ff are the rests with the boxes, g g is the shaft. h is the chuck on the shaft, i and j are the irons shown in Figs. 170 and 171. k k k are the slotted holes in the top or loose table, by which the machine can be moved backward or forward to suit any size of wheel. These slots should be six inches long. l, the table, lies on the platform b, and bolts and thumb screw taps pass through the slotted holes. This table should be one inch by twelve inches by eighteen inches. M HI arc the pieces shown in Fig. 167. n n are iron attachments to fasten the machine to the wheel bench. It will be noticed that they are fastened at both ends with staples, so that the machine can be lifted off by taking off the two taps that hold the braces c c to the bench legs. The holes in the braces c c should not be over a half inch apart. This machine makes tenon boring easy work, and all the tenons are straight.óBy H. L. CORDREY.
