I have a rather nice cherry captains desk that I built in high school, so
around 87.  It was to have turned front legs (decorative between some base
feet and the desk top) which have yet to be done and the heavier/lower)
drawers have yet to acquire glides but have been just sitting in the
carcass floating free.  Its been happily serving duty in my dads house the
entire time though.

That only puts me at 31years for that so not in the same league really.

We won't talk about the stack of mostly dimensioned lumber that is to be
the bed frame because its not even close to a decade old yet (over half way
but we're trying not to count to closely).

I'm sure more than a few of you can beat anything here so far ;)
