In the “Modeller-designer” No. 7, 1982, in the collection “Second youth spinning wheels” was told about the device for spinning the sewing machine. The novelty and simplicity of the design interested me and I did the same, only on the basis of the motor from the fan Orbita-3. Unfortunately, this spinning wheel I have never worked, although I reduced the weight of the bobbin to 18 g: when rotating, it not behind the stag, even after the motor shaft was mounted a flywheel. Then I decided to redo the design in their own way — the opposite is true; the rotation speed of the stag was smaller than the bobbin. Turned out, in my opinion, not bad: the device works reliably.
The spinning wheel consists of a base on which you installed the motor from the fan stand with a Central shaft and two brackets intermediate pulley and the guide sleeve.
At one end of the Central shaft made the M6 thread on another shot of the flats in the cross section get a square. Then, in the end, in a hole with a diameter of 3.95 mm pressed stud M4. For reliability it is soldered to the shaft.
The spool consists of two disks, sawed from a plastic coil of the wire mounted on an aluminum tube of length 73 mm, cut off from ski poles. On the outer side of the disc is glued getincome plate thickness of 1 mm. To one made a square hole for coupling to the shank of the Central shaft; the other with a round hole with a diameter of 10.1 mm.
