I
really can't say enough about this method of jointing. After I did one side of all the 2 X
4's I decided to do the other, as well. I was going to joint only one edge, but the
operation went so smoothly, I wanted to try something.
|
This is what I
wanted to see. I wanted to put all the 2 x 4's side by side to see if the edges were
jointed well enough to be a tight "table top". They passed the test. I laid a
clamp across just to keep them in line, but they all fit very nice and tight.
I can't say enough about the JointAbility's ability to joint wood.
Now on to the next step.

As I
said earlier, I will use OSB on both sides of the frame/insulation section. Since these
panels come from the manufacture very square, I will use them to keep the whole assembly
square. After having measured and re-measured, I am cutting the panel to the right length
and width.
|
I have
set the saw stop to give the right height and cut the 8 pieces that I will need.
|
 |
 |
With the frame
pieces cut to length, I use a square to mark where I want the beadLOCK loose tenons to be.
|
I normally clamp the
workpiece AND the beadLOCK jig together in the vise. These 2 X 4's are so long and heavy,
I found it easier to clamp only the board in the vise.
|
 |
 |
I use a ViseGrip to hold the beadLOCK jig on the 2 X 4. The arrow
indicates the window which I simply line up with my pencil mark. This ViseGrip is the one
that is part of my Kreg Jig outfit it works very well holding the beadLOCK in
place.
|
I am using the larger,
1/2" beadLOCK jig so I have installed a long 1/2" bit in my power drill. You can
see that I have applied a piece of masking tape to serve as a depth stop. I am drilling
holes 1 1/2" deep.
I have found that if there is a trick to using the beadLOCK, it is to let the
drill do the work. I use little pressure when drilling, particularly at the start of the
hole. These 2 X 4's are quite green, so I bring the bit out occasionally to clear the
chips away.
|
 |
 |
Once the holes have been
drilled, I use an air gun to blow out the chips. The beadLOCK procedure calls for
"re-drilling" the first set of holes for this purpose. I found that with this
construction lumber that re-drilling still left too many chips. Instead, I used a small
screwdriver to loosen the chips and then blew the mortise clean. [Note: be sure to close
your eyes when doing this.]
|
I have set the saw stop at 2 7/8" and cut a number of the 1/2" beadLOCK loose
tenons. The slightly shorter tenon will allow for some room at the bottom of the mortise
for sawdust and glue.
|
 |
 |
While the board is still in
the vise, I brush glue over the bottom 1/2 of the tenon.
|
I tap the
tenon in the mortise. It is a wonderfully, tight fit. I double check the length of the
exposed tenon I do not want to find it too long for the mating mortise.
