A Precise Table Saw from an Electric Hand Saw

Step 10 Making a shim

The first shim needs to be the width of the steel bar on the miter gauge minus the thickness of the blade.  Notice the red line.  It aligns the left side of the bar with the left side of the saw blade's teeth.  The temporary fence shown is clamped to the saw base so that the face nearer the blade's teeth aligns with the right side of the steel bar.  The green arrow indicates the width of the shim needed. 

Remove the steel bar. Turn the saw right side up and rip your shim from a straight piece of wood while holding the fence against the wood.  Make the shim as long as your saw table is deep.
