Lathe Bed
Cast Iron frame with ground top surfaces and 4 leg extrusions, the leg
extrusions have large rectangular flanges for strength and are also used
to support the ON/OFF switch assembly at the tailstock end and the
motor mounting plate, drive pulley assembly at the headstock end.
There are threaded holes in the base of the legs to accept the integral
bolts of the rubber feet. The far headstock end has a flat metal plate
cover to guard the drive pulley cluster. The far tailstock end has four
threaded holes to accept the mounting bolts for the optional bed
extension. If the bed extension is not used the mounting face is covered
by a small metal plate (secured by 2 screws, which also have threaded
fixing holes in the end of the bed). The metal plate also prevents the
tailstock being slid off the end of the bed. If the bed extension is fitted,
the plate should be transferred to the end of the extension.
Headstock
Tower casting, which is bolted to the bed. It has housings for the
bearings that carry the headstock spindle. At the rear of the headstock
is an open void to give access to the driven pulley cluster, it is guarded
by a flat metal plate cover.
Headstock
A steel spindle threaded 1" UNC (8 tpi) to mount faceplates, chucks etc.
Spindle
The spindle is bored out to accept 2MT drive centres et al. The driven
pulley cluster is keyed onto the shaft between the two mounting
bearings. There is a small handwheel mounted on the outer end of the
spindle to facilitate hand rotation, whilst setting work up, changing
speed etc.
Motor Assembly The motor is mounted on a plate which is shaped to provide a pivot
point on one side and a handle shape on the other. There is a radius slot
on the handle side through which a clamping bolt is fitted. The clamping
bolt (with a washer) fits through the motor plate and into a threaded hole
in the bed leg flange casting, and when tightened will clamp the motor
plate in position to maintain tension on the drive belt. The drive pulley
cluster is mounted on the motor shaft, and is accessed through the
cover plate on the bed.
Banjo
The toolrest mounting arm. This is a shaped cast iron casting, the base
of which is machined to lay flat across the bed of the lathe. The 'mound'
at the end of the casting has a machined hole to accept the stem of the
toolrest. There is also a threaded hole through the 'mound' into the hole,
which has a lift and shift lever handle bolt inserted into it, to screw
against the stem of the toolrest, in order to clamp it in position. The
main body of the casting has a long, lever ended actuating rod though
it, the lever end protruding beneath the 'mound', the other end held in
place by a circlip. The actuating rod performs a cam lift action on a
pendant bolt. The pendant bolt hangs between the two bed surfaces and
carries the clamping dog. The underside of the main body is slotted
along its length to allow it to be slid back and forth about the pendant
bolt in order to position it. When the cam lift is operated the clamping
dog pulls up against the underside of the bed and holds the banjo in
its set position. The clamping dog is adjusted using the nut on the
pendant bolt.
