cation on machine alignment before beginning work.
Check machine level and alignment at regular periods to
ensure continued lathe accuracy.
Headstock check:
1. Take a light cut with a cutting tool over a 6" (152mm)
length of 2" diameter (50mm) steel bar gripped in the
chuck but not supported at the free end.
2. Micrometer readings at each end of the turned
length (at A and B) should be the same.
3. To correct a difference in readings, loosen the four
headstock hold-down screws (I) behind headstock
and (J) under the headstock, then adjust the offset
adjusting screws (K).
4. After adjustment, tighten screws (I)/(J) first and then
screw (K).
