Quick Start Guide to using the GrooveCenter

The GrooveCenter is used in preparation of the router operation to position the router fence.

The most common uses for the GrooveCenter are:

– setting up the fence for making centered slots or grooves in a work piece
– setting up Lock Miter Bits
– setting up Reverse Glue Joint Bits

Contrary to all other set-up procedures, the router fence is positioned and fixed in its position BEFORE chucking in the router bit. Once in position, it should not be moved again.

A split fence facilitates subsequent inserting the router bit. If the fence needs to be moved out of the way for chucking in the router bit, its position can be registered on the table surface with stop blocks.

  • To start, the GrooveCenter’s “Collet Pin” is inserted in the router’s collet.
  • With the workpiece in the GrooveCenter’s Vise, the fence is brought forwards to just touch the Fence Pin and fastened in place.
  • The fence is now in the correct position for making a centered groove or slot. The GrooveCenter can be removed and the Router Bit inserted.

This photo illustrates how the GrooveCenter registers off the router collet:


In this set-up, the router arbor is equipped with an Xtreme Xtension (www.routertechnologies.com).  Look here for more detail.

These photos illustrate a typical lay-out for setting up the fence for a perfectly centered groove on the face of the board: the Fence Pin indicates the position of the fence:



Once the fence has been fixed in its exact location, the GrooveCenter is removed and the router bit inserted.

The set-up is complete for the routing operation and a perfectly centered groove is made!


This measuring technique is unaffected by the router bit diameter and  the result of the measuring operation  is always perfect, whatever the board’s width or thickness.

The GrooveCenter is therefore truly a fail-safe set-up tool for the router table.


The GrooveCenter accepts boards as wide as 4-1/2”.

For ease of reference (though not required for a set-up operation), there is a width graduation on the top of the GrooveCenter’s housing, marked in inches as well as metric.


The GrooveCenter comes in a stylish wooden box, that protects it with foam padding. Two hex keys are supplied for any necessary adjustments
