Well, it is back to
the silver chest project, but this isn't Jessica. It is Andrea who will help
me complete the chest. Jessica's busy schedule made it impossible to get
together.
So Andrea it is, and I am lucky to have her help. She has stacked
the boards that were re-sawn by Jessica.

Her first task was to run each of the
boards through the thickness planer. The resawn boards were very smooth for
resawing. She really is "dimensioning" the boards. She has four that will be
the sides, and she wants these to be 1/2". The top boards will be 3/4" —
thicker so that we can round over the top slightly and then there are two
other boards that are 3/8" that we will use the drawer. While these are the
finished dimensions she wants, she left each a little proud so that she can
finish sand to 180 grit after the panels are made.
|
I am not sure I made a
good decision to just pull the planer out and run the boards without the
dust collector. I have two. One is permanently attached to the router table
and the larger one is "land locked" on the other side of the shop. We had
very little to remove, but it sure mounts up as dust.
Maybe this is sharing too much with you.

Back at the worktable, Andrea double
checks her inventory of boards.
|
If you have followed this project from
the beginning, you will recall that one of the things we want to do is to
have the boards' end grain match the mating panel on all four corners.
Here Andrea has carefully matched the boards. There are four: two
for front and right side and the other two for back and other side.

A close-up of these boards show that
they have pretty good widths but that they need jointing before Andrea can
glue them as panels.
Her mark will allow her to joint the individual boards and get them
back in the right order for glue up.
|
You know by now that we at WoodShopDemos
use the router table quite a bit. For edge jointing, we prefer this to the
long bed jointer that I have.
Andrea has installed a CMT 2" long 1/2" flush trim bit in the
router. It is the workhorse for edge jointing.
|

|

|
We are using the CMT router table
which has a specially shaped fence that allows Andrea to add two spacers
behind the outfeed fence. There are two groove sets. The other set allows
for a greater removal of material. We like the shallow set that yields about
a 1/16" on each pass. She has also moved both the infeed and outfeed fences
close to the bit.
|
She pulls the fence forward
and positions it so that the outfeed fence (with the spacers) is aligned
with the pattern bearing of the straight bit. She can see that on the far
right of the square, the infeed is back about 1/16". That is exactly what we
want for edge jointing.
|

|

|
She joints each board by making as many
passes as is necessary. The "trick" is to listen to the cutting action. Even
with the hearing protectors, she can hear the bit remove wood. When it
removes wood along the entire length, the board is edge jointed.
To compensate for any slight "tilt" to the router, she runs the
boards so that one edge is run with the face down and the other edge with
the face up. This way if there is any "tilt", the opposing edges will mate
perfectly.
