END GEAR TRAIN

Drive from headstock to gearbox is transmitted
through a gear train enclosed by the headstock
end-guard. Intermediate gears are carried on an
adjustable swing frame (M).
Gears must be thoroughly cleaned before fitting
and backlash maintained at approximately 0.1mm.
Lubricate gears regularly with non-slinging grease,
e.g. BP L2, Mobilgrease Special, or equivalent.

SLIDE WAYS ATTENTION

Tapered gib strips are fitted to slideways of saddle
crosslide and top (compound) slides so that any
slack which may develop can be justified.

Ensure that slideways are thoroughly cleaned and
lubricated before attempting adjustment. Then
reset the gibs by loosening the rear gib screw and

tightening the front screw. Check constantly for
smooth action throughout full slide travel; avoid
overadjustment which can result in increased
wear-rate and stiff or jerky action.

CROSS-SLIDE NUT

This is adjustable for elimination of slack which
may develop in service. Reduce backlash by the
cap-head screw in the rear of the nut, then make
only small adjustments by the cap-head screw.
Before operating the cross-slide, check several
times by hand to ensure smooth operation
throughout travel.
