I
know you have projects that go on and on...well I do too. Except that this project, the 18
drawer chest, got put away for the winterI plum forgot about it. When I was
reading the Projects on the Menu Page, I saw it...so now I will finish it up. The 18
drawer fronts, from all different exotic woods, sit at the right, and I have just cut all
the drawer components.
|
I have a number of
dovetail jigs and my first task was to think of which one would work best for this
project. There are drawers of three different heights and the drawer elements are of
1/2" poplar.
My first thought was to use a variable spaced jig, but a friend was complaining
about the Incra Ultra "not having variable spacing," and I started to think
about this. Strictly speaking, that is true, but very misleading.
Let me explain.
|
 |
 |
With my three drawer sizes
in hand, I look in the book of Incra Jig templates. I start by looking for one bit
that will work well for 1/2" stock. AND then, find the templates that both use
that bit and will work on the three different drawer heights.
|
It takes a second or
two to locate the template that will work on the widest stock. It will be template DOVJ
and I will be able to cut 3 tails. The general rule for laying out dovetails is to have
one-half a pin at both ends. Less than that may be too weak a pin; more will be just a
"heavier" look than you may want. My red marks indicate the amount of pins I
will have for this wide board.
|
 |
 |
For the mid-size
width, I place it on the same template and I can get two tails, but the pins will be just
a little wider that in the first. Will that matter? I don't think so. The drawers will not
be seen side by side, so minor differences will not be noticed..
|
The smallest side is the hardest to figure. In many jigs, there would be no
way to handle such a small side. You might think you can just switch to a smaller bit, but
in fact, a smaller bit wouldn't be large enough to cut this thickness of wood. That fact
applies to all dovetail devices. If I use the same template that will work for the
others, I will have 1 1/2 tails. That won't do at all.
|
 |
 |
So I move the small piece
of wood down the displays of templates, but still staying with the exact same bit.
The next template down (DOVK) would work, but the pins would be very
narrowand weak.
|
The next listing is for
the DOVL. which is way to wide.
|
 |
 |
Next, is
the DOVM which is just right. Does it sound like the story of Goldielocks and the three
bears? Well that is really the point of this exercise, there will be several templates
that can work, but one will be "just right." You don't have infinite
variability, but there is almost that with the number of templates available and your
imagination.
|
To illustrate the
cutting of the drawer joints, I will do the widest joint all the way through
step-by-step. But I will show the three drawers at the end, so you can see how the
slightly different pin sizes will look.
|
 |
 |
In that, I
am adding a false front to the drawers, the dovetail could be of either 1/2-blind (upper)
or through (lower) style. Months ago when I first reviewed the Incra Ultra, I was
pleasantly surprised to find that both are easy to make. The decision comes down to
aesthetics.
The picture here is of those corners I made during the earlier report. For
this project, I will do the 1/2-blind dovetails.
No more decisions to make, so let's make the dovetail corners.
