Possible causes and corrections
The most common cause for this is that the tenons are stored in a
humid environment, and they have swelled from moisture absorp-
tion. Store the tenons in a cool dry environment.
The mortising bit may have been improperly sharpened or sharp-
ened too many times. Replace the bit.
Make sure the workpiece is securely clamped before plunging.
Check the Stop latchs.
Check the calibration of the Horizontal Position Gauge (sight
gauge).
Don't plunge the mortising bit into the work too fast. This may
cause the joiner to move during the plunge.
Make sure the friction pads on the front of the joiner are not worn,
damaged, or missing.
Take care not to tilt the joiner while plunging.
If the mortise slots were registered from the bottom of the base-
plate, make sure there is no dust or debris under the joiner.
Make sure the fence is properly locked at the desired height set-
ting.
Inspect the height adjustment lock to ensure it is not broken (slip-
ping).
Make sure the fence is set to the correct angle (e.g. 90 de-
grees).
Make sure to hold the Domino joiner fi rmly to the work surface.
Make sure the proper plunge depth is set.
Make sure the joiner is tight to the face of the workpiece.
The mortising bit may have been sharpened too many times and
is too short.
Excessive dust may be present inside the linear slide.
Excessive glue may be present at the bottom of the mortise.
Plunging speed too fast. Slow down the rate of your plunge.
Low-grade materials and plywoods will tear out more than solid
woods. Decreasing your plunging speed will improve the results
but may not eliminate the problem completely.
Dull mortising bit.
The plunge speed is too fast and the bit is not cutting the sides
properly. Slow down the plunge speed.
