Quick-and-easy height gauge

Raise your cutting accuracy to new levels.

Set the cutting depth of tablesaw blades easily using this adjustable gauge. To ensure accuracy, we outfitted it with a steel rule. See Source below for the parts.

Start by cutting the body to size from 3/4" maple, as shown on Drawing 1. Plow a 13/32"-deep groove, sized to fit your rule, in one face of the body, where shown.

Next, set your dado blade to 1/4" and cut the combined rabbet and groove in the body for the sliding bar. To do this, place the gauge body on edge (ungrooved face against the fence). Cut the rabbet/groove in three passes, with the last one at 15/8", where shown on Drawing 1a. Drill and countersink the screw hole. Then, sand and finish the body.

Use a coping saw or scrollsaw to shape the 1/4" acrylic sliding bar to the dimensions shown. Create the adjustment slot by drilling a pair of 5/16" holes where shown and cutting out the material between them. Smooth the edges of the slot and the outer edges of the bar using a fine file. Buff the outer edges if you want to make them supersmooth. Now, scribe a cursor line on the back face, where shown.

Attach the steel rule in the groove using double-faced tape. Place the bottom end of the rule 1/4" from the bottom of the body. Then, install the sliding bar.

To use the gauge, set the cursor line to the desired height. Hold the sliding bar in its groove while adjusting the gauge to keep the bar square with the base. Place the body on the tablesaw top beside the blade, as shown in the photo, then raise the blade to set the height.

Alternate way to mount the ruler - countersink some rare earth magnets in the base (presuming you're not using a non-magnetic stainless steel ruler). Works really well and allows for recalibration.

Trick with the cursor line. Use a utility knife to scribe the cursor line (only scribe once!) into the back side of the Lexan where it lays directly onto the rule. Use a permanent marker and draw over the line, then quickly wipe away the excess marker ink before it dries. You won't wipe the ink out of the scribe line itself, and you're left with a perfectly sharp, legible line for the cursor, and with it laying directly onto the rule, there will be no parallax error in reading it.

IMHO, I think the .25" off set is to allow for the teeth to clear the top of material to allow the carbide teeth of the blade to clear cut wood. As for enlarging image, if you are using Windows as OS, no matter which of the three Browsers you use (FF, IE, Chrome)hold the control button down and scroll with the mouse wheel, scroll wheel up enlarges and down makes it smaller.

For rickandajansplace, if you look carefully at the picture, the acrylic peace has a cursor line 1/4 inch up, so the ruler needs to be 1/4 up also. This allows you to line up looking through the plastic as opposed the the plastic edge. You should be able to put the ruler on the bottom and forget about the cursor line.

As to the ruler touching the bottom, NO, it wouldn't be better as there is a scribe line on the lexan to compensate for this. Open your eyes before you post.
