Figure 8-2: Change gear setup
Adjust gears to mesh with upper and lower gear.
Placing ordinary paper in between gears helps to adjust for
correct gear spacing (... remove the paper afterwards!).
Reinstall the pulley cover.
8.3 Taper turning with tailstock
Mount the work piece fitted with the drive dog between
centres. The drive dog is driven by the face plate.
Lubricate the tailstock centre with grease to prevent tip from
overheating.
Figure 8-3: Taper turning between centres
To turn a taper, offset the tailstock, loosen the locking screws
(Z, Fig 8-3) and use screws (Y) to adjust.
After taper turning, the tailstock must be returned to its
original position. Turn a test piece and adjust until the machine
turns a perfect cylinder.
8.4 Taper turning with top slide
By angling the top slide, tapers may be turned.
Loosen two hex nuts (A, Fig 8-4) and rotate the top slide
according to the graduated scale (B).
