Default And on to finials

Like Fred said, most boxes are made in the end grain orientation, Wood
movement will be pretty consistent so that when it does move, and it
will, the lid an bottom will move in the same directions so that you
may get an oval, but the lid will match the oval. Flat grain moves
differently. If the top and bottom are made from the same piece of
wood, when you get movement, they will match, but you will get both
oval/horizontal and height/up and down movement, so there can be gaps.
Boxes are generally small because if you make one bigger than about 2
to 3 inches, there is more wood movement, and it can cause problems
with fitting the lid.

As far as finials, you could use end grain on a flat grain box as the
finial is small, especially the tenon which you insert into a hole,
and movement will be very minimal. The thing I worry about is that
people tend to try to take the lid off using the finial. You do not
want a tight fit. You can make a finial out of one piece, but, if it
is flat grain, the finial will probably break before you finish
turning it as cross grain in a finial is weak. I do turn some simple
boxes where I make a knob for lifting the lid off, that is all from
one piece of wood. In most cases, finials are made from a contrasting
color of wood, which generally looks better.

Would it be safe to assume that some here have one-piece tops, with
the top and finial combined?


Hello Kevin,


Most small boxes are made with the grain parallel to the axis of
rotation on the lathe (or endgrain). One reason for this is that the
wood in this orientation does not change with the weather as much as
in the other orientation. That said, if you put a lid on it, it is a
box.


However, if you seal the wood properly when you finish it, there is
generally less change with the weather, because more moisture can't
get in and any moisture remaining in the box is pretty well retained
there.

Sorry Kevin,

I forgot to answer your question about finials. On side grain boxes
like you are making, it is always necessary to put on a finial with
the grain oriented in the spinal turning mode, otherwise they will
tend to break easily. You can turn a round knob on the lid, that will
generally stand up to use, but the fancy finials are all turned in
spindle fashion and attached after the box is completed.
