I just finished reading another thread on this group where one of those
classic wreck arguments was going on. This one centered on whether
1/64" was "close enough" when dealing with wood. The perfectionists
describing 1/64th as a canyon and the pragmatists countering. Well I
think you have directed us to one project here where 1/64th is adequate
accuracy.

After just reading that post yours brought a smile to my face. Thanks.

Wood moves. Metal doesn't. The realists know that wood can
sometimes expand or contract 1/64", or more, the idiots ignore that
fact. I don't think I can even measure wood that close, let alone cut
it that close.

Which is why I stayed out of that particular conversation... g

Come on, now, JOAT. You had me until you said idiots...

Metal DOES expand and contract, just as wood does, just not from
moisture - it rusts instead. g

Everything is a set of compromises - and some applications simply
don't demand the precision some people are eluding to.
But some applications might - like this:

When cutting these segments, an error equivalent to thickness of a
piece of card stock paper will cause a cumulative error that makes
this segmented ring impossible to realize. I work with tolerances
greater than .01" when doing this.

Does it matter on a table or a bed? Nope.

Does it matter on this?:

Yes, it does.

Wood does expand and contract, but it does so in concert - all pieces
generally doing about the same bit of movement. If you're really
good, it all stays together over time. If you're not - you have a
pile of fire starter kindling. g

JMHO,

Well, I wanted to be polite. After all, I "am" a people person.

Yeah, I though so... ;-)
