Building Childrens Furntiture

Some pieces shown in this book have rabbets or grooves that do not run the
full length of the wood from edge to edge. These rabbets start at a point
inside from one edge, and end before they reach the oppo-site edge.

To make such limited inside rabbets or grooves on a circular saw, use the
method shown in the photos. First raise the saw blade to a height equal to
the depth of the rabbet desired. (If a groove is being cut, a dado saw blade
is used.)

Next, with the fence set at the proper distance from the blade, use a square
to mark vertical lines on the fence, one line indicating where the outside
arc of the saw blade first emerges above the table and starts to cut, and the
other line pointing to where the inside arc of the blade descends below the
table and the cutting ceases.

For cutting a groove, these lines are the only ones needed on the table saw,
but for cutting a rabbet a similar set of lines should be drawn horizontally
across the table surface to indicate these same limits of the saw cut.

Next, mark two short lines across the top of the wood directly over the points
where the groove or rabbet underneath is to begin and end. Then, without
turning on the saw, lay the wood over the blade and flush against the fence,
back it up until the for-ward line on the wood is lined up with the outside
line on the fence, and put a clamp on the fence at a point where it will hold
the wood in this position and not let it slip back.

Now, turn the saw on, back the wood against the clamp stop, holding it at an
angle above the spinning saw blade, and then carefully lower it down on the blade
until it is lying flat on the table top. Immediately advance the wood along
the fence until the rear line on the wood comes into line with the rear line
on the fence. Then stop and remove the wood.

If a rabbet is being cut, turn the wood on end and re-peat the operation, this
time using the guide lines on the table surface to start and stop the cut.

To finish the groove or rabbet, use a narrow chisel to square up the ends of
the grooves which were left in an arc by the saw blade.
