7.10.220” Bed Extension Kit (6294900)

Tools required:

8mm hex key 10mm hex key Straight Edge

1.Slide tailstock away from edge of bed.

2.Place a straight edge against bed and raised area of leg (Figure 16). These two areas should be flush. If they are not, support the lathe (with fork lift, hoist, etc. – USE CAUTION!) and loosen the screws holding leg to bed. Nudge leg as needed, then retighten screws firmly.

3.Install 20-inch bed extension in the same manner as described in section 7.10.1.

Figure 16

4.Install elevating system (Figure 17) to bed extension with four 3/8" screws and washers, and to lathe leg with three 1/2” screws and washers (A, Figure 17). Note that top screw is installed from inside the leg and secured with the nylon nut (B). Refer to exploded view, section 17.5.1 if clarification is needed.

5.Install handwheel and tighten setscrew.

Figure 17

Remove screws in bed extension to swing away the bed, or to move bed to lower set of holes. Note: If heavy loading makes handwheel turning difficult, a 19mm wrench can be used to turn hexagonal shaft (Figure 18).

For outboard turning, where headstock is moved to opposite end of lathe to accommodate large bowl blanks, you can (1) mount the 20-inch bed extension to the lower set of holes on the Lathe frame, and (2) mount an extension post [included with kit] to the tool rest base. See Figure 19.

For larger outboard work, an outboard turning stand (# 6294732) is available; see section 13.0, Optional Accessories.
