I have been fixing the MiniCup sailboats (homebuilt 12') and there is

Some people build welded boats, and they often cut the plates with a
torch. To a tolerance of perhaps .0625 or even greater. If the plates
don't quite meet you just use more rod.

Although I don't use it much for boats, I have an incra-jig for wood
that has a repeatability of 1/500th of an inch...

That's all well and fine, but the tolerance will exceed that because
wood just isn't very stable. It shrinks and swells a lot due to
temperature and moisture.- Hide quoted text -

Yes, but working with rock maple which is pretty stable it makes nice
dovetails. You do figure in the glue lines and such, but at least you
know where zero is.
