In answer to the question of how to get the
concave "inside" of the spoon - Proxxon
mini-grinder with flapper sander wheel..
If you have a table saw, you've probably
seen the method of cutting a cove into a
board by passing the board diagonally
acrossed the saw blade. By making a
sweeping pass over the surface, varying
the depth of cut by varying the angle
as you go, you can "sand out" a spoon
shape. There's a medium and fine
2" curved metal abrasive wheel available
that lasts a lot longer than the flapper
sander that Proxxon sells. But at
$40 US each they're gonna have to be
on a future wish list.
