Parts Identification and Description (Continued)
Leadscrew A round centre rib switch/lever, which allows selection of the leadscrew to
selector ‘autofeed’, i.e driven by the change gear train, (indicated by a triangular
waveform sign), or ‘manually’, i.e. driven by the handle on the end of the
leadscrew, (indicated by a ‘hand’ logo).
Lathe bed Solid cast, machined bed. The face machining gives two flat bearing
surfaces, whilst the ancillary machining gives a dovetail form to the bed, and
forms a rigid stable locating and guiding system for all the machines
components.
Saddle Main casting that is precision machined to marry with the lathe bed. It moves
parallel to the main axis. It mounts the traverse slide.The accuracy of the fit of
the saddle to the bed is maintained by the ‘gybe’ strip set in the rear of the
saddle dovetail.
Traverse slide Mounted on a ‘dovetail’ land machined onto the top of the saddle. The
accuracy of the fit of the slide is maintained by the ‘gybe’ strip set in the right
hand side of the traverse dovetail slide. The bed of the traverse has two ‘T’
slots machined into it to allow the mounting of the tool post or the compound
slide accessory.
Traverse slide A wheel and rod handle, mounted on a shaft that is anchored into a housing
control machined in the front of the traverse slide, the shaft is threaded and is
engaged in a dog fixed to the saddle, enabling the traverse slide to be driven
back and forth across the saddle perpendicular to the main axis. There is a
graduated ring (thimble) on the neck of the handle to allow the movement of
the slide to be measured.
Tool Post A double sided tool post. Each tool position has 2 securing bolts to clamp
the tool in place. One tool mounting has a fixed ‘bed’ the other has a
‘rocking’ bed in a curved seating to allow the tool to be tilted slightly fore
or back to allow precise tool heights to be achieved, without the necessity
for fine shims. The tool post is secured into either one of the ‘T’ slots by a
caphead bolt passing through the tool post into a ‘T’ slot keeper. The tool
post is not keyed into the ‘T’ slot so it can be turned to any angle before
being locked in position.
