G0554 Gear-Head Floor Lathe
Gap Removal
The Model G0554 comes equipped with a gap
section below the spindle that can be removed for
turning large diameter parts or when using a large
diameter faceplate.
The gap is installed, then ground at the factory
during lathe assembly for precise fit and align-
m
ent. Factors during the remaining assembly
apply additional forces to the gap; therefore,
replacing the gap to the original position will be
very difficult. If you choose to remove the gap,
we don't recommend attempting to replace
it.
To remove the gap:
1. Find the two taper pin nuts located on the
bed
of the gap (see Figure 29).
Figure 29. Lathe gap.
2. Using an open-ended wrench, tighten the
nut. This will cause the taper pin to release.
Remove the taper pin and repeat for the sec-
ond
nut.
3. Remove the four socket head cap screws.
4. Tap the outside of the gap with a dead blow
hammer
to loosen, and remove the gap sec-
tion.
Tailstock
The tailstock (Figure 30) of the Model G0554
lathe can be used to support workpieces with the
use of a live or dead center. It can drill or bore
holes in the center of a part, using a drill chuck
fitted with a #3 taper and a drill, or bypass the
drill chuck and use a #3 tapered shank drill. The
tailstock can also be used for cutting shallow
tapers by using the offset adjustment.
To operate the tailstock:
1. Slide
the tailstock to the desired position.
2. Pull up on the tailstock lock handle to lock
the
tailstock in place.
To operate the tailstock quill:
1. With the tailstock locked, push down the quill
lock
handle to unlock.
2. Turn the quill feed handle clockwise to feed/
move
the quill towards the spindle, or coun-
terclockwise to move away from the spindle.
3. Pull
up on the quill lock handle to lock the
quill in place.
