This week, I asked Andrea to take a new
look at the silver pieces insert. My fear was that we might make the
chest a little too small and this insert wouldn't fit. I found a long scrap
stick that Andrea is marking. We will make a "story pole" of the length and
width dimensions of the insert.

She uses a Japanese pull saw to cut on
her mark. Can you believe this: Andrea said this is the first hand tool she
has ever used in this shop. We will have to remedy that.
|
She makes one for each of the
dimensions. We have to be very careful when laying out the miters that we
measure for inside dimensions. Rather than to measure the outside and
subtract the thickness of the wood, we will simply make sure that we only
concern ourselves with inside dimensions.

An aside for a moment. This is Elena
working with the Festool Domino Joining System. The upper Systainer holds
the machine, itself, and beneath it is a Systainer storing the Domino
tenons.
WoodShopDemos has been extremely fortunate to get this System in
way before its official release, and we have been "playing" with it.
As a system it does so much that play is not the operative word,
study and use is much more to the point.
In the next few months we will be using this new Festool product.
It is easy to give you the "Features/Benefits Story" but Festool is doing
that very well with a super website introduction. This one is from the
headquarters - to the
official site.
Just select the language you want, and go.
We used the various screens extensively when we first got the machine.
And not to confuse you, the two Systainers rest on a Festool
Dust Extractor CT MINI. As with
all Festool products, dust extraction plays an important role in the design
and operation of the tool.
We have quite a long feature underway with Elena so you will be
seeing the rest of this introduction in the coming weeks.

You can see
in a glance what the Domino Joiner can do — make elongated holes for loose
tenons. Here, Elena is using the System in its very basic function — panel
glue up. It is perfect for it, better than biscuits, but the use is the
least of the many applications of the Domino Joiner. To really get to
appraise it, you will have to follow with us over the coming weeks when we
will use it in panel glue ups, chair construction,
countertop/backsplash/edging, cabinet making, rail and stile construction,
face frame building, drawer making, small chest miter work, large door construction — to
name a few. Fact is, we haven't scratched the surface. What we are trying to
do is to use it. That's right use it as we make things and see
if it can serve us better than what we would normally do.

Back to Andrea and the silver chest in
progress. Her first task is to
figure out which Domino Tenon to use. Her mahogany is just over 1/2" or 13mm and
ideally, she would like to have a tenon 1/3 that width or 4+ mm. The smallest
the Domino uses is 5mm which she places on the edge to get an idea of how it
will work. It should work well if she can place the mortise in the exact
center of the edge.
|
She holds the Domino Joiner. It weighs about
the same as a quality biscuit jointer — and that is where the similarity
ends. This Domino tool is part of a joining system.
She will be using it this time for panel glue up which is important, but traditional dowels and biscuits have done an adequate job here for
years. It will be interesting to see if the Domino System gives us an
improved joint.

The Domino System uses four different
size bits — 5, 6, 8 and 10 mm in diameter. Now if you haven't learned metric
or feel comfortable in that, not to worry. Do like I do and go by eye. In
the photo two above, Andrea was holding the 5mm tenon on the board edge. She
doesn't need to know the metric width of the board, she can select the right
tenon by eye. It looks good. And a warning to old cabinetmakers and
woodworkers like me, we say we are too old to learn metric but then find out
it is a much easier system to use. I measure the board width. It is 13 mm
wide, one third of that is just over 4. Now think of the imperial way.
It is 10/16ths and one third of that is 3.5/16ths or 7/32's. I think
half of the mistakes I have made over the years were measuring mistakes — I
wonder why.
|
In the picture above, Andrea uses the
small wrench supplied to lift up a catch to release the body from the front
end. At right, she can withdraw the motor assembly so that she can change
bits.

|
To remove the bit, Andrea with her right
hand, presses the shaft lock button (not visible from this view.) That
allows her to easily loosen and remove the bit. The unit accepts four
differnet size bits — 5, 6, 8 and 10 mm diameter.
