Optional router bits for variably spaced through and half-blind dovetails.
Bit Selection for Through Dovetails
8° Dovetail Bit for Tails
The pins

must fit into the sockets

. So the dovetail bit’s depth
of cut
B
must be equal to or a little greater than the pinboard
thickness

.
Measure the pinboard thickness

and select the dovetail bit with
2
1
B
3
4
5
the correct depth of cut
B
from the following pages (bits must be
8° for through dovetails).
Straight Bit for Pins
The matching straight bit is listed just below the dovetail bits. The
5
⁄16" diameter No. 140-8, 8mm shank is the only straight bit you
need with the Superjig.
Guidebush
All joints on the Superjig are routed with the e7-Bush, or all but
box joints with any
7
⁄16" OD guidebush (min. barrel depth
1
⁄4").
See page 68.
Shank Selection
Note: You will require a router with an 8mm or
1
⁄2"[12,7mm] collet
to use our 8mm shank bits. For a
1
⁄2"[12,7mm] collet router you
will require our
1
⁄2"[12,7mm] to 8mm collet reducer No. 172-8.
Note: This is a collet reducer
➃
, not a collet
➄
. It does not replace
the collet, it slides directly into your
1
⁄2" collet. Do not remove
the collet nut when installing the collet reducer.
