1. The left saw has a diameter of 20 mm, a bore of 6 mm, and a thickness
of 0.2 mm. The right saw has a thickness of 0.1 mm, too thin for making good-looking graduation marks. |
|
 |
2. The arbor disassembled. The boss on the arbor has been carefully machined for a tight fit of the saw blade to minimize runout. |
|
 |
3. Accuracy is maximized by machining the arbor without removing
it from the chuck. |
|
 |
4. Machine a small relief groove at the junction of the shoulder and mounting
