[THE GITS]

Time to fit the trigger.

We know this must obviously be on the centre line of the gun, simple so far. What we need to know is how deep do we need to fit it. Time again to re assemble our bits. WE can now measure the difference in height between the top of the trigger and the top of the track or the surface of the recess. In this case they were equal so no awful math.

The trigger is 11mm wide, so to allow for a little varnish I have decided that a 12mm cutter will be perfect. With the guide fence still set at exact centre of the gun, fit the 12mm cutter. Ones used for fitting kitchen worktops are ideal being 60mm long. Sit the router back on top of the gun, now carefully lower the cutter onto the track surface. Now we can set the depth of cut to that of the trigger mechanism. This can be done using either a measuring device or the trigger itself.

Unless the cutter has a bottom cut, plunging the cutter into wood is a difficult thing to do. It may help if you drill a 10mm hole at each end of the trigger recess that we marked with the marking knife earlier. Again using 2mm cuts, remove all the wood from the trigger recess.
