Calibrating the Locating Pins
It is important that the two locating pins are perfectly spaced from the center of the mortise hole for properly aligned mortises. The factory default setting is in the neutral position.
1.Using the procedure described in “Using the Locating Pins” on page 11, plunge a
2.Insert a Domino tenon into the resulting mortise and fit the two pieces together without glue.
3.Examine the alignment of the ends of the two blocks of wood. Note that you are only concerned about the ends where the locating pins were used.
►If the two ends are flush, no adjustment is necessary.
►In the example shown to the right, the adjustable pin is too close to the mortise; increase the distance of the pin as described below.
4.If an adjustment is necessary:
a.Loosen the bushing’s setscrew using a 2 mm hex key.
b.Using a large screwdriver, rotate the eccentric bushing to move the adjustable pin closer to or farther from the mortise slot.
►The factory default (neutral) setting is shown in the lower right photograph. The screwdriver slot is in the vertical position.
►Each hash mark represents 0.25mm (0.010 inch).
►Don’t turn the bushing any farther than
c.Retighten the setscrew.
5.Repeat the process to verify that the adjustment is correct.
Calibrating the Horizontal Position Gauge
The horizontal position gauge (also called the sight gauge) is used for aligning Domino tenons to a pencil mark on the workpiece. If the gauge is not perfectly centered over the mortising slot, the two workpieces will not be aligned when the joint is assembled.
Calibration Procedure
1.Take two pieces of scrap wood, and draw a thin line on each piece where a tenon is to be placed.
2.Set the mortise slot width to the narrow setting (page 8).
3.With the middle line of the sight gauge lined up on the pencil line, plunge a mortise slot into each piece of wood.
4.Join the two pieces of wood together without glue, and examine the alignment of the original pencil lines.
5.If the pencil lines are not aligned, loosen the two screws on the sight gauge and slide the gauge sideways as noted in the upper image.
