Installation

To install the taper attachment:

1.  DISCONNECT LATHE FROM POWER!

2.  With the assistance of a helper and using 

a 6mm hex wrench, remove the four cap 

screws holding the splash guard on the rear 

of the lathe.

3.  Using a 5mm hex wrench, remove the two 

leadscrew end-cap cap screws shown in 

Figure 4.

Note

: Make sure to keep the correct race with 

its original bearing, and do not hammer on 

the casting or chisel the inner races out. The 

inner race has a loose fit. If it is difficult to 

remove from its seat, be patient and spray 

some penetrating oil into the bore and 

carefully work the race out from the grease 

suction that is holding it. You can also soak 

the casting in mineral spirits to break this 

suction.

7.  Using a #2 Phillips screwdriver, remove 

the eight flat head screws and the taper 

attachment top plate (Figure 6).

8.  Using a 5mm hex wrench, loosen the slide 

block set screw, as shown in Figure 7.
