It has been stated clearly here...but I would re-iterate it...If you use the
dowels method..be CERTAIN that you use the GROOVED dowels. You need the
groove to allow the excess glue a chance to get back out of the holes. I did
a project once, and used regular doweling material ( non-grooved) and
puzzled forever why I couldn't camp the material easily. Seems like
something was forcing it apart. It was the excess glue trapped in the bottom
of the glue holes!!!
