Actually most, the wider looking ones, are 1/2" and made up of 4, 1/8"
wide strips. Sometimes 1 walnut, 2 maple, and another walnut.

The trick is to insure that the strips will add up exactly to the width
that you remove.

Typically I use a pattern to guide a 1/2" top bearing flush cut bit to
cut about 1/8" deep into the glued up cutting board. I then cut down
that grove with the BS. Now the cutting board is two pieces.

With a larger flush cut bit I remove the remainder of the wood that the
1/2" bit started removing. The bearing rides against the 1/8" recess
created by the 1/2" bit.

Then sandwich and glue them all, the thin strips and the cutting board
pieces, back together. Do this whole procedure for each individual set
of stripes.







I've made a few of these after seeing the technique in FWW. I like
Leon's idea of the first pattern bit and template, I've always used a
guide bushing on the router table and one _must_ keep the board square
to the bit (no rotation allowed). Works good for simple curves but
errors creep in if one is not careful.

Leon, how long is your pattern bit? The bits I have would require a
template at least 3/4" thick.

There is a short FWW video of the process (if you can finish it with out
barfing from the vertigo 8^)
