MARK V Miter Gauge

Printer friendly PDF copy of article

An accurate Miter Gauge is essential to making square & true cut-offs and precision miter cuts. Dropping or bumping the Gauge...even regular use...can tend to alter its accuracy.

Periodically, it's a good idea to check the squareness or angle of the Gauge to the Saw Blade with a drafting triangle or a precision, adjustable arm protractor. Another device made especially for this purpose is a see-through plastic Angle Setter. Remember, too, that the protractor on the Miter Gauge is not a precise measuring instrument, but should only be used as a guide.

That's why you should take extra care in setting the Gauge's Auto-Stops for 45-degree left and right and 90-degree settings. This way, when you're ready to make straight or 45-degreed mitered cuts, just go to the Auto-Stops and everything should be OK. When making a critical, angled miter cut (other than 90 or 45-degrees), you should always use one of the set-up devices listed above.

Finally, it's a good idea to use paste wax or a machine table lubricant such as Top-Cote or Dri-Cote to reduce friction between the Miter Gauge Bar and the Worktable Slot.
