You know, sometimes the most simplest thing turns into
analysis paralysis.

Want to make ZCI insert for my JWTS-10 Jet. I bought a ZCI some
time ago and I measured the thickness - 3/8". I measured the one
on the JET, same and just for fun, I measured from the leveling
flange to the top of the saw 3/8".

However, when I go looking for instructions, most are calling for
1/2" ply or phenolic. The differences in thickness are usually
handled by rabbeting the ZCI so it sits flush.

To me, it sounds like 1) another router set up after I
already mount the flush bit to trim the blank 2) more time.

Why wouldn't you just use 3/8" ply or phenolic to make
a ZCI, trim it, drill for leveling screws and be done? I just
don't know why 1/2 material would be that much better?

Exactly what I did with my inserts bit did use 1/2" baltic birch on a JTAS
10L,
BUT make it even easier, put the leveling screws on the bottom and you end
up with a flat top with out holes for debris to collect in. I have never
ever had to readjust the screws after the initial set up.
