mechanical table use, wheel length minus vertical wheel length. Mechanical watch escapement is fine, in is not easy to directly file circle can be exposed wire press is quadrilateral, octagon that order file edge angle, the last file edges and corners circular.
< p > balance front end is inserted into the hole of the main plate should not be excessively exposed (to the main plate through hole), to avoid it is wiped with center wheel or wheel box and other parts. When the handle shaft is pulled out of the pin position, the split wheel should still exist in the main hole of the main plate, otherwise the shaft will not only rock, but also damage the matching of other parts. Wheel diameter should be slightly smaller than the diameter of the main plate small wheel, wheel rotate in the hole without shaking is flexible.
