Halved. New subject: The halved or lock joint. Wood: Poplar. Preparatory: Cut two pieces as required, making allowance for working. Exercises.

1.   Make pieces of form and dimension required.

2.   Mark the cuts for the lock joint. Be sure

that they are made small enough to insure a tight fit, but not small enough to bruise the wood in pressing the joint together.

In doing this, do not measure with a rule to obtain the-marks, but mark directly from the pieces which are to come together. Use the gauge for the depth mark. Square down for sides of the cut

3.   A. Make the cuts with the backsaw. Be sure to cut inside of tlines, but leave the lines on the wood.

B.   If too tight, do not chisel by guess, but make an accural knife mark to receive the edge of the chisel in making the cut.

C.   Inspect for defects.

4.   Stain or shellac to suit taste.
