Doweling...

I use dowels to join the panels together, the sides together, the sides to the top and bottom. The main reason for this type of joinery in this particular application is that it allows me to have a slight overhang of the top and bottom panels vis a vis the sides, to accommodate the chamfered edges.. Alternative methods of joinery that allow this are mortise and tenon, sliding dovetails. etc. I use dowels as I feel comfortable with this joinery and it has not let me down so far. A considerable amount of accuracy is necessary in aligning the dowel holes that mate with the top, bottom and side panels. There are also different methods to accomplish this. The simplest method is to use dowel centers, next would be a doweling jig of some sort.

Instead, I make a doweling guide which is simply a block of wood with the exact dimensions , thickness and length of each of the side panels. The concept is to use the guide to create mating dowel holes in the ends of the panels. I use standard size fluted dowels and have pre-measured and carefully oriented each of the side panels to its corresponding top and bottom panel. In the photo, I am aligning the doweling guide on one of the side panels. I since removed and bored two other holes in this particular guide for a total of ten dowel holes. Also in the photo, the face of the side panel is displayed, the back of this panel has a rabbet running lengthwise at the left hand side. The first dowel hole from the left is offset to accommodate this.

As I continue with this boring process ( no pun intended) there are eventually a total of 80 holes bored into the ends of each of the panels. A stop is used to bore to the correct depth to accommodate standard size dowels. Afterwards, each of the bored holes is checked with the depth gauge of a caliper and install the dowels, first on the side panels, then these panels to the top and bottom panels. Some test fitting, and the glue up begins...
