TAILSTOCK/BED KEYWAY ADJUSTMENT
The tailstock
✿✌
Fig. 15 supports the workpiece
when spindle turning. To prevent the tailstock roofing
during turning, the tailstock is fitted with an
adjustable set screw
❀✌
. This set screw bears
against the keyway
❂✌
on the underside of the bed.
To adjust refer to Fig.15. and proceed as follows; with
the tailstock lock
❁✌
loosened, tighten the
adjustable screw
❀✌
moderately against the keyway
❂✌
, then loosen the screw by about
1
⁄
4
turn.
Now with lock
❁✌
still loosened, slide the tailstock
along the full length of the bed. If it binds or sticks at
any one point, loosen the adjustable screw
❀✌
just
enough to allow the tailstock to slide smoothly. If the
tailstock can be rocked, tighten the adjustable screw
just enough so that it will not bind when sliding the
full length of the bed.
INSTALLING THE BRASS SLUGS IN LOCKS
Brass slugs
❃✌
Fig.16. are required under the lock
bolts
❁✌
of both the tailstock and the tool rest base.
The purpose of these slugs is to securely grip the
bed when locked down without damaging the bed.
Locate the two brass slugs
❃✌
from the loose parts
supplied. Insert a brass slug into the threaded hole of
tailstock Fig.17. and into tool rest (not shown) and
screw the lock handles into the holes until tight. Now
screw the other two clamping handles into their
locating holes.
ALIGNMENT OF TAILSTOCK CUP CENTRE TO
HEADSTOCK DRIVE SPUR
The drive spur and live centre are used for spindle
turning and should always be in alignment. To align
the centres, refer to Fig.18. and proceed as follows:
Slice the tailstock towards the headstock, so that the
two points of the centres are very close, but not
actually touching, tighten the tailstock lock. If the two
centres are aligned proceed to the next section. If the
centres are not in line loosen the foot bolt
✱✌
Fig.19.
by about two turns (do not drive the bolt forward as
this could loosen the bed connector clamp and
alignment of the key way will be lost). Using a
3
/
16
″
hex. key wrench loosen the hex. socket screw
✪✌
located on the rear of the headstock which secures
the bed. Gently swing the tailstock, so that the two
points are in line, then retighten the set screw
✪✌
and the foot bolt
