(Fig. 2)
The base has a slider, a strip of wood 1 in. thick and 10 in. long, wide enough to slide smoothly between the bed pieces, nailed to its bottom, 2 in. from the rear end. Two 1/2-in. holes are bored through the baseboard and slide. Two 1/2-in. bolts are run through these holes and through another slide and board which runs on the under side of the bed.
When the nuts on these bolts are tightened, the headstock is firmly clamped to the bed. A half-round, wedge-shaped piece is fastened with screws in the frame against the front end, to serve as a brace against any strain, and will also add to its appearance. The spindle is of tool steel or steel tubing, 3/4 in. in diameter and 14 in. long. Threads are cut on one end.
A hardened steel collar, 1/4 by 1-1/2 in., is riveted on the spindle so it may turn against another collar of the same size on the headstock. Another collar is fastened with screws to the rear end piece, and a collar with a removable pin is fixed on the spindle. These should be fitted so as to revolve easily against each other and yet have no end play. The bearings are of brass tubing drilled for a spindle. These are inserted and wedged in the headstock, 6 in. from the bed.
Care should be taken to see that they are in line. Small holes are drilled from the top for oil. The pulleys are 2 in. wide with the diameters given in the drawing. They are fastened to the spindle with a removable pin.
(Fig. 3)
A good chuck for this lathe is made, as shown in Fig. 3, of a piece of shafting 1-1/2 in. in diameter and 2-1/2 in. long. A 1/2-in. hole is drilled through its center and one end reamed out and threaded to fit the threads on the end of the spindle. A setscrew is fitted over the 1/2-in. hole. A center for turning wood is also shown. Many centers, drills, etc., can be made of 1/2-in. tool steel.
