Stand shelf :
You can make an extra shelf that rests between the legs if
you wish (see Fig 7).
Installing bed extension : (JET Option # 719401)
The bed extension can be mounted to the upper or lower
holes of the lathe.
Mounting the extension to the lower holes allows use of the
tool support during outboard turning (Fig 8).
Mounting in upper holes increases the spindle length
capacity of the lathe.
Have an assistant hold bed extension flush to end of lathe
bed, and insert four screws with washers (P, Fig 9).
Snug screws just enough to hold bed extension to lathe
bed.
Unscrew stop bolt (N) from lathe bed and insert it into hole
at end of bed extension.

Top surfaces and inside ways must be flush to allow
smooth movement of tailstock.
Slide tailstock over joint where beds meet, so that clamping
nut is centred over joint. Lock tailstock clamping handle;
this will align the beds.
Securely tighten screws (P) in bed extension.
Installing cage guard : (JET Option # 719002)
Loosen set screw (B, Fig 10-1) and remove outer collar.
Attach guard to the bracket by inserting the rod and lifting
up on the plunger (A).
Fig 10-1
Place the collar against the bracket and tighten set screw
(B).
There are two detents that will hold the guard in place.
One is for turning and the other is for when you need the
guard up and out of the way (Fig 10-2).
