might be a pat answer to the question, if there isn't I'm more than
willing to listen to the group but don't insult me.
1. I gave you a perfectly acceptable answer
2. I wasn't trying to insult you - ergo the smiley - but was pointing out
that you could have easily and (most) effectively answered your question for
yourself.

Pat Answers
Ah, yes...the pat answer...the be all and end all of existence.
Unfortunately, there is rarely a pat answer to anything other than "it
depends".
In your case, it depended on the type and quality of the plywood, how tight
you wanted the dado/tongue to be, how long they were to be and what you
meant by "Is 1/32" wider than the plywood thickness enough." Enough for
what? To put together? To stand without support? To glue well?
In my case, I want what I think of as a "snick" fit; the tongue goes into
the dado easily with moderate pressure, doesn't wobble and when separating
the pieces there is sort of a "snick" feel/sound...sort of like popping your
cheek with a finger And no, I can't better describe it. Trouble is, a fit
that is fine on, say, a 4" dado/tongue probably won't be if the dado/tongue
is 30"...it will probably feel too tight. It would probably be OK if I
slightly beveled the edges of the tongue - which I regularly do either with
a small plane or a four-in-hand file depending on the material - but even
then it will likely take considerable pressure to get the tongue into the
groove/dado.
Tom Watson gave you a nice way to make a tongue that is reasonably precise
in size. Works most of the time; however, it would be very difficult to
impossible to cut a tongue in that manner on the four foot end of a sheet of
4x8 foot plywood. Or on the short end a 1x6 foot one either

I think most people that have read newsgroups - ANY newsgroup - for a while
would agree that many of the questions could easily and more effectively be
answered by the poster if s/he only thought about it for a moment and/or
drew on their empirical experience.
That doesn't mean I don't think people *shouldn't* ask questions - many
times the asking provides answers that are useful though not necessarily
germane - merely that they could often work out a solution for themselves
and in so doing they have a solution (and brain exercise) that can be
modified for use in other circumstances.
