Don't knock a good strategy! Measure it a smidgel
over, cut it once with a saw and then a bunch with a
plane until you get exactly the fit you want! Deep
down, nobody really notices the exact dimensions, so
long as all the bits fit together right. (Admitedly,
that plane thing does not apply to plywood so much.)
My advise for new woodworkers - know how to sharpen
every tool you own, and make sure it's sharp before
you try to use it. Every time I've used a dull tool I
find myself looking at my work and thinking "Gah, that
looks like crap!"
This includes power tools! I've got a pair of cuts I
made with a dull circular saw. The first one looked
like a sine wave, so I tried really hard to stay on
the line the second time. It looked like a sine wave
with a higher frequency! Fortunatly those edges got
burried later in the project (my house).
This includes pencils!
