SPINDLE
The spindle is the working part of the lathe. It is
mounted with the new QUATRE PRECISION
BEARING SYSTEM. The 2 directional axial load
provides greater performance for both inboard and
outboard turning operations. Both ends of the
spindle are threaded to allow the attachment of
accessories, such as faceplates and chucks. The
inboard end of the spindle has a right hand thread
and the outboard has a left hand thread. The
spindle is also hollow to allow for deep boring and
knocking out centers. (Figure 32)
The knockout bar provided is for the ease of
knocking out centers through the headstock or
tailstock.
SPUR DRIVE CENTER - HEADSTOCK
The spur drive center (A-Fig. 33) is used in
conjunction with the revolving center in the tailstock
to support cylindrical work such as chair and table
legs, railstool handles etc.
When loading a project blank onto the spur drive
center, do not use a hammer or similar as damage
to the headstock bearings may result. The pressure
obtained via the tailstock handwheel should be
sufficient to provide adequate stability when using
softer woods. For harder woods, shallow diagonal
saw cuts in the end section should be made plus a
small hole in the center. The spur center can be
directly knocked into the wood by using only a soft
mallet. Never use a steel hammer as this will
damage the taper shank.
A
LIVE CENTER - TAILSTOCK
The revolving cup center (A-Fig. 34) is used for
supporting spindle turning projects that can not be
held suitably in a chuck.
It can also be used as a safety device to support
face plate work for as long as possible, especially
during roughing down stage.
