SPINDLES.
5. To see that the spindles are in the center of the rings, and that your rings are in good condition. A poor ring will make two-thirds more waste than a good one, and the frame requires three times the cleaning that it does with a good ring. Slip your finger round inside of the ring; if it feels notchy the ring is poor. Take it out. Rings should be looked over every time you scour. That should be every six months. Steel rolls should be rubbed with one-twenty emery cloth once a year, with a little oil.
