The thickness of the center section of the top assembly will be 3/4 inch, however the mitered routed trim will be 1 inch in thickness, the thicker portion overlapping the table framework.
When the top is not visible or readily visible, I usually do a straight plank system, however for our top which is visible, I like to design the top used to build the entryway table with a bit more interest, please refer to plan view. If preferred, straight planking can be used, but should be built with the three 1" wide mitered rails.
The left, right and middle panels used to build the main section of the entryway table top assembly are edge joined from 2 – 5 3/8 inch wide pieces, and joined by 6 dowels, i.e. 4 near the outer edges and 2 in the center. The left and right panels are 12" long and the middle panel is 20" long.
Excluding the outer perimeter mitered rails, all joints should incorporate 3 to 6 dowels. My design is probably overkill and includes 3 sets in tandem (6 dowels).
The outer mitered rails should incorporate 5 to 10 dowel joints. My design uses 5 sets in tandem (10 dowels). This procedure is not as daunting as it may appear. Use the following guidelines:
(1) Use appropriate check marks or numbers.
(2) Leave widths and lengths marginally oversize to allow for final trimming.
(3) Construct from inner core outwards.
(4) Use distance gauge and spacers as required.
When gluing, assembling and clamping, particularly in long assemblies like these, always ensure the faces are flat and true by using a suitable straight edge and with the use of cauls.
Once the first 5 components used to build the entryway table top assembly main section have been glued and cured, the reason for always referencing from the same edge will become apparent.
In other words you now have a fairly reasonable straight edge to begin trimming this part of the table top. Using that straight edge against the fence, trim a small (32nds of an inch) off the edge, then rotate the board and repeat the process at the opposite edge. Keep repeating this process until both edges are perfect and parallel.
I modified my fence on the Saw Stop table saw (the original was a disaster!) The new oak fence is absolutely true and square.
