Bummer :-(

It has been too long since I've used that jig to know for sure. Things
that come to mind are...
- Material thickness variance
- Router bit heat expansion (not so plausable)
- Some chips under the base plate or in the clamp space during initial
setup.

Just an FYI that in production shops using Baltic, we always puttied
with white putty and sanded out any dovetails or box joints and it
actually looks really great.

I purchased and Akeda jig a few months ago (lots of raves on the new

were made from solid birch. *I was not so lucky on the second set of
drawers. The sides are 1/2" baltic birch and the front and back are
3/4" baltic birch. *A front board will finish the drawers.

I made some tests to establish the height of the bit and got it "just
right" after a couple *of tries. I then proceeded to do the half blind
joints for the first 5 drawers. *I cut the tails in the sides for all
five drawers. *Then I switched to the pins on the five sets of front
and back pieces for the drawers. *I was very disappointed to find that
the joints did not fit correctly. *The tails do not mate tightly to
the pins - there is a 1/16 inch gap; i.e., the is a gap holding the
two pieces apart by 1/16 inch.

I checked the pieces with my test pieces. *The tails in the drawer
sides fit perfectly with the pins in my test pieces. *Something went
wrong when I cut the pins on the front and back pieces. *My first
thought was that the router bit dropped or the router depth changed.
But, it would have *happened just as I changed from tails to pins -
too much of a coincidence! *The guides are all at the same height and
are in there tight.

Anybody got suggestions on what I did wrong?
