Try Squares: How to Adjust the TS-2v2 / TS-1v2 Try Squares

Field Adjustable for Precision Accuracy

Both the TS-2v2 and TS-1v2 Try Squares are designed to be field adjustable, allowing users to fine-tune the tool for optimal 90° accuracy. Below are two methods based on your available tools.

If You Have a Known 90° Reference Surface:

1. Loosen Screws:

   • Using the correct-size hex key, loosen one screw slightly, then loosen the remaining three screws fully.

2. Position the Square:

   • Place the square against the known 90° reference (such as a certified machinist square or reference block).

   • Determine the direction of adjustment needed.

3. Adjust the Square:

   • Clamp the blade (not the handle) gently in a wood vise.

   • Lightly tap the handle in the direction required to align the blade with your reference.

   • This may take a few tries—check the alignment after each adjustment.

4. Secure the Adjustment:

   • Once the square mates cleanly with the reference:

     • Tighten the screw that was left semi-tight.

     • Re-check for accuracy.

     • Tighten the remaining three screws carefully.

Important Note:
The set screws are stainless steel—do not overtighten, as excessive force can shear off the screw heads.

If You Do NOT Have a Known 90° Reference:

1. Place the square against a known straight reference edge (e.g., a jointed board or straight ruler).

2. Scribe a line along the blade.

3. Flip the square 180°, align the same edge, and scribe a second line.

4. If the two lines diverge, the square is not true. The angle error is twice the difference between the lines.

5. Use the same adjustment method outlined above to align the blade until no gap or deviation appears between the two scribed lines when flipped.

This method uses the "flip test" to empirically establish a true 90° angle, without needing a certified square.
