When I
left off last week, I was just starting to dry fit the sections together. The mahogany is
quite uniform but I am selecting boards that I think will work nice together.

My
task is to cut all the boards down to about 5 1/2". That is simple. The challenge is
to have the dovetails match up and look uniform.
Using the Incra Jig and the "C"cuts, I made a template. I have very
carefully narrowed this template so that the tails at both ends are the same. In fact, the
ends are exactly 1/2 tails. This way, when the sections abut the next, the two half-tails
will make a whole tail and hopefully match all the others.
[Yes, that is Lacewood. I had some thin stock left over from my practicing
re-sawing. It makes a very handsome template.]
|
When I have the template
placed over the dovetails, I place a razor blade where I want to trim the bottom. I found
that the razor blade worked better than scribing a pencil line.
|
 |
 |
I
place a second razor blade at the other end of the board using the template.
|
I have inserted the piece
to trim in the JointAbility. I move the board in until the razor blade just touches the
white trim guide.
|
 |
 |
The arrows are pointing to the razor blades at both ends of the long side boards.
The blades are just touching the JointAbility's guide board, so I am clamping down the
ends.
|
This is
one step I do not want to forget: I am removing the razor blades.
|
 |
 |
|
This close-up shows the
cornerpost and double dovetail trim is being edged very well. On the other end where there
is great chance of tearout, I make the cut very slowly.
Note that for all these router cuts, there is 1/8" or less to cut. In
the few instances where there was more, I made several passes.
|
 |
 |
I check the seam of the
first two boards. They fit well and the dovetail is the correct size 11 more boards
to go.
|
I use the razor blade to
mark an end panel. You can see that I have the panel in the dovetail sockets and
overlapping the end. Using this method, I can match the board width to the dovetail
corner.
|
 |
 |
I align the end panel on
the JointAbility. I repeat this process board by board. It seems like a slow way to
do it, but it ensures that every board is jointed exactly that makes it all worth
while.
