I clamp the jig in
place over the two tables. The cross line that can be seen clearly in the last photo is
used as a sighting line and is lined up with the intersection of the two tops.
I add a second clamp to be sure. A Bessey clamp holds the two tables together
for this operation.

I have carefully set
the plunge depth to the exact thickness of the fastener and have tested this on the MDF
side. I do not want to take any chances with the phenolic table.
I plunge and cut in several passes. The MDF and phenolic cut well with this
bit, but the dust has no where to go and can bind the cutter. The up-spiral cutter does a
much better job at exhausting the dust than a straight cutter but still needs some help.

The portable vacuum cleaner sucks the area clean between passes. This slows the operation
a bit, but the end result is a very clean and crisp cut.

I use a small
metal dowel that is included in the package to tighten the ball in one end. It is now a
perfect, tight joint.
While I probably will leave the platform on most of the time, it can be
disconnected and reconnected quite easily.

Before I turn the top back
over, I want to correct the corner blocks I installed several weeks ago.
The inked lines show the amount of travel that I had in the top, so I drilled
oversized holes (3/4") and am using wide washers. I do this on each of the four
corners. This gives me quite a bit of lateral adjustment of the top, but once adjusted, I
can fasten the blocks so that the top will be snug.

Everything is back together
and I am happy to report that there is absolutely no play in the Incra Jig mounting.
This is good because I am about take on some new projects that will put this
great system to the test.
