Set up your dovetail jig for the first piece of wood. Run the wood through the jig to form the dovetail notches.
Reset the jig for the complementary side and run the other piece of wood through the jig.
Apply wood glue to the two pieces and slide them together. Wipe away any excess glue and clamp the two pieces together. Let the pieces dry for 24 hours.
Set the wood block onto your lathe and start the rotation.
Gently press into the wood with your carver and shave off layers to form the inside of the bowl.
Work around to the side of the block and gently press it again to form the outside.
Slow down the rotation and sand the inside and outside of the bowl with 220-grit sandpaper to smooth out any rough edges and cut marks.
Coat the bowl with food-grade varnish and allow to dry for 24 hours or soak the wood with mineral oil and allow the bowl to absorb the oil for 24 hours.
