Introduction: DIY Digital Height Gauge

A quick jig can make the difference in a woodshop. This height gauge helps measure and set cutting tool heights and thicknesses for rabbets, dadoes, chamfers, etc. Since it incorporates a digital caliper, the dial is easy to read, precise and accurate.

This tool came in handy building the light box project – I hit the rabbet depth and thickness dead-on each time.

Step 1: Tools & Materials

DIY Height Gauge

Materials:

  • Small Clamp, either F- or C-style will work, but the clamp must clamp well. I find spring clamps don’t work.
  • 2 #8 1-1/4” Wood Screws
  • MDF, roughly 6”x10”, either 1/2” or 3/4” thick
  • Calipers with a depth bar

Tools:

  • Scroll saw or band saw
  • Miter Saw
  • Drill Press with 1-1/2” Forestner Bit
  • Drill with Countersink & #2 Phillips Bitdsc_4242

Step 2: Assembly:

Assembly:

  1. Lay out the gauge on a piece of MDF. I have linked to a SVG & DXF for those readers with access to a CNC or laser cutter. You can also use this PDF to print out a template.dsc_4244
  2. Use a drill press to drill out the top of the cut out.dsc_4247
  3. Use a miter saw to cut the gauge into two halves.dsc_4258
  4. Use the scroll saw to trim the waste and complete the cut out.dsc_4259
  5. Drill two pilot holes, countersink and attach the halves with wood screws.dsc_4263

Step 3: To Use:

Use:


To use, clamp the fractional dial caliper to the upright. dsc_4474Set the gauge on the tool table. Then, drop the depth gauge so it touches the table surface. dsc_4479Zero out the reading.dsc_4487 Reposition the height gauge over the tool itself. dsc_4484Raise the tool itself until the dial reads the negative of your needed height.dsc_4486

A couple of questions:

What's the purpose of the shallow hole at the top of the shape? Is it to provide a secure spot for the foot of the clamp?

Where do you use the magnets? I'm assuming on the base to secure to the table top?

The original plan was to attach the caliper with rare-earth magnets. I picked up a cheap magnet hook from the hardware store to incorporate but found out it didn't work once I completed the stand. I left them out of instructions, but you can still see evidence in the construction.
