For outboard turning, where the headstock is
moved to the opposite end of the Lathe to
accommodate large bowl blanks, you can (1)
mount the 18” bed extension to the three lower
holes on the Lathe frame, and (2) mount a
vertical extension post [included with the
optional bed extension] to the tool rest base.
See Figure 9.
For large outboard work, an outboard turning
stand (# 6294732) is available – see page 37.
Shelf Assemblies (Optional)
The double ledges on the inside of the Lathe
legs will provide support for a shelf (not
provided), which is convenient for storing larger
items while keeping them easily accessible.
Figures 10-11-12 illustrate three methods of
creating a shelf, using common lumber and
basic tools.
IMPORTANT TIP: It is unlikely that a full-size
shelf can be completely built and then inserted
between the Lathe legs. Therefore, construct the
shelf in pieces and insert screws only after the
shelf has been established beneath the Lathe.
Shelf Style 1 (Figure 10)
Lay two 2x6 boards flat upon the inner ledges.
Boards of 48” length are suitable, although 48-
1/2” is optimal.
Shelf Style 2 (Figure 11)
Lay two 2x4’s (or 2x6’s) on edge into the outer
ledges. Boards of 48” length are suitable, 48-
1/2” optimal.
Cut two pieces from a plywood board, and
screw them to the top edges of the 2x4’s. (One
48” plywood piece will not fit through the legs of
the Lathe; use at least two pieces.) Make the
plywood pieces flush with the outside edge of
the 2x4’s.
Shelf Style 3: (Figure 12)
This is a basket-style shelf consisting of two
2x6’s and dowel rods. The advantage of this
design is that most wood chips will fall through
the shelf instead of accumulating on it. The
instructions below are for building the shelf
shown in Figure 12.
Materials used:
2 – 2x6’s (48” suitable, 48-1/2” optimal).
8 – wood dowels, 4’ length, 5/8” diameter.
