SUPERJIG - CHAPTER 3
The Leigh e-Bush and
Optional Guidebushes
The guidebush is the vital link between router and jig. All joints created on a Superjig are routed with the unique
e7* elliptical guidebush, a Leigh innovation that provides precise joint fit adjustment for box joints and sliding dovetails.
If your router doesn’t accept the e7-Bush, you can use an alternative guidebush with some limitations.
*Supplied with each Superjig. U.S. Patent No. 8,256,475. UK Patent No. GB2443974. Patent Pending in Canada.

The Leigh

is used to rout through, half-blind,
single pass half-blind and sliding dovetails on a Superjig. The

The Leigh
e7-Bush
that comes with your Superjig is a
unique template guidebush that is adjustable in size. Unlike regular
circular template guidebushes
, the
e7-Bush
is slightly elliptical
in cross section
. This simple innovation effectively changes the
guidebush “active diameter size” when it’s rotated, and provides
benefits not possible with a standard round guidebush.

the active diameter by .020"[,5mm] providing minute adjustment and
recordable settings for perfectly fitting box joints.
