CHAPTER 6
Routing Wider Boards
This chapter assumes you are familiar with all
procedures in this user guide and you have
established good joint fit and flushness using
test boards before routing wide boards.
6-1
Getting Started
The Box Joint & Beehive Jig can be used to rout box joints on
boards wider than the jig width, up to 17-13/16"[453mm]. This is accomplished easily
using a step-over cam and simple procedure.
This example uses 3/4" box joints on 3/4"
thick boards.
Procedures for routing 1/2" and 3/4" joints are identical.
6-2
Parts Required
3/4" and 1/2" box joints are routed with the included Leigh
No.160 1/2" straight bit and the Leigh e10 guide bushing (eBush).
No other bit diameter
and guide bushing combination may be used.
Maximum board thickness for both
joint sizes is 13/16"[20.6mm]. Depth of cut can be increased beyond the board thickness
for raised joints.
Note:
Optional 1/2" diameter spiral upcut bits may also be used.
