Tailstock 

Large  casting  that  mounts  the  tailstock  barrel,  it  is  moved  on  and 
clamped to the lathe bed to allow the tailstock barrel to be moved to the 
proximity of the  work piece. It can  be  offset from the  central axis  of the 
lathe to allow for taper turning between centers. 
 

Lead  screw  / 
Rack guard 

A  formed  mental  plate  that  covers  and  protects  the  leadscrew  and  the 

rack. 

Tool Post 

A  four  sided  tool  post.  Each  tool  position  has  3  securing  bolts  to clamp 
the tool in place. The tool post is located on a central pivot mounted on 
the  top  of  the  compound  slide.  It  has  a  four  pos

ition  ‘click’ locator, that 

locates it to its major axis, but it can be held at any angle by the tool post 
locking clamp. 
 

Tool post cover 

Fitted  to  compound  slide  it  is  there  to  provide  protection  from  “flying 
swarf” whilst turning between centers. 

Motor   

Single phase 230V      220V 50HZ    100V 60HZ    50Hz motor. 1H.P. 
 

Tailstock  barrel 
lock 

Small ‘swing’ lever that locks the barrel in place once it has been moved 
into the required position. 
 

Tailstock  drive 
handle 

This engineer’s wheel and handle controls the movement of the tailstock 
barrel,  backwards  and  forward.  It  has  a  graduated  ring  (thimble) 
mounted on the neck of the handle so that the amount of movement can 
be monitored. 
 

Tailstock barrel 

Steel  barrel  bored  with  No.2  Morse  taper  to  mount  various  tooling, 
centers,  drill  chuck,  reamers  etc.  the  barrel  has  a  travel  of  50mm,  this 
travel  allows  the  mounted  tool  or  centre  to  be  brought  into  controlled 
contact with the work piece. 
 

Mounting feet 

Shaped in the casting of the lathe bed, the two feet have 14mm slots cut 
into  them  to  enable  the  fitting  of  two  12mm  bolts  to  effect  the  rigid 
fastening of lathe onto it’s stand? A work bench? 
 

Lathe bed 

V  rail  and  flat  rail  bed,  precision  machined  to  provide  an  accurate 
mounting  for  the  headstock  and  a  precision  guide  for  the  movement  of 
the saddle. It also mounts the tailstock in an accurate relationship to the 
main axis of the lathe. 
 

Saddle 

Main  casting  that  is  precision  machined  to  marry  with  the  lathe  bed.  It 
moves  parallel  to  the  mail  axis.  It  mounts  the  traverse  slide.  It  also 
mounts  its  control  handle  and  the  auto  feed  or  thread  cutting  engaging 
lever. 
 

Saddle control 

This  engineers  wheel  /  control  handle  is  mounted  on  a  shaft  that  goes 
through the apron of the saddle; there is a pinion mounted on the end of 
shaft  that  is  permanently  engaged  with  the  fixed  rack  on  the  lathe  bed. 
This enables the saddle to be moved back and forth along the lathe bed. 
N.B. Remember this handle is PERMANENTLY engaged to the rack and 
during thread cutting or auto feeding  will turn  with the movement of the 
saddle. 

Auto feed lever  This lever engages the saddle to the leadscrew to enable the auto feed 

or  the  thread  cutting  function  of  the  lathe.  Move  the  lever  down  to 
engage  the  feed.  As  there  is  no  synchronising  dial  indicator  fitted  for
