Jointing 

 

In order to craft a good woodworking project, it 
is necessary to have a square piece of wood 
to start with.  The way to do this is with a 
jointer.  You need one straight edge and one 
flat face.  After you have these, you can plane 
to thickness and rip to width and the resulting 
piece will be square and true on all four sides.  
At this point you can begin building your 
project. 

 

 

 

Direction of the Grain 

To avoid tear out, always feed the material in 
the direction of the grain.  If the direction of the 
grain changes half way through the board, try 
taking lighter cuts at a slower feed rate.  If the 
results are still unsatisfactory, try turning the 
material around and feeding the other way.

Edging 

(Figure 14)

 

To give a good straight edge for gluing or 
joining, set the fence square with the table.  
Remove the least amount of material required 
to obtain a straight edge.  Hold the best face 
of the piece firmly against the fence 
throughout the feed.  When finished you will 
have a perfect starting point for your project.

Once you have a good edge it is time to 
eliminate any warp or cup on the board.  Keep 
in mind the outfeed table is the reference point 
and once the material is past the cutterhead, 
downward pressure should be applied to the 
outfeed table only.  Putting downward 
pressure on the board over the infeed table 
will bend any cup or warp prior to hitting the 
cutterhead and after the pressure is released, 
the cup will spring back.  At the same time try 
keeping a constant feed rate in order to give a 
good smooth cut with no burn marks
