Smithy Midas 1220 XL - Manual (Page 17)

2.
Carriage - The carriage consists of the saddle and apron. It moves by hand or power
along the bed, carrying the cross slides, compound rest, and toolpost. Its function is to
support the cutting tool rigidity and move it along the bed for different operations. It locks
into place by tightening the carriage lock under the cross slide handwheel.
3.
Change Gears - The change gears cut different thread pitches. They also determine
the feed rate. Five change gears come installed on the machine; others are packed with
it.
Figure 5.2 Your machine arrives with this gear configuration. The C gear, behind B
meshes with D. Note the top two gears are permanent.
4.
Compound Rest - Mounted on the cross slide, the compound rest swivels to any
angle horizontal to the lathe axis to produce bevels and tapers. Cutting tools fasten to a
toolpost on the compound rest. The calibrations on the front of the base are numbered
in degrees from 60 degree right to 60 degree left.
5.
Cross Slide - The T-slotted cross slide (Figure 5.1 and 5.3) moves crosswise at 90
degree to the lathe axis by manual turning of the cross-feed screw hand-wheel. It also
serves as the milling table.
Figure 5.3 The cross slide moves laterally when you turn the cross slide handwheel.
