Before assembling the parts of the miniature walnut chair, sand the various shell sections against a sanding block to make sure the cut edges of the shells are even and will fit togehter without gaps. If necessary, sand any edges which stick out from the line of the other walnut pieces. Clear out any parts in the center of the shell, leaving the shells smooth on the inside surface.
When you have all the back sections sanded on the cut edges, apply a small amount of glue to each cut edge and assemble the sections into the chair back as shown. Wipe away any excess glue. If possible, clamp the sections or use a magnetic gluing jig or some heavy boxes to hold the shell sections tightly together until the glue dries.
Glue small acorns or beads to the base of the chair seat section as shown, checking that the seat base sits square on the bead or acorn feet. Leave to dry.Leave the parts to dry thoroughly. Note Walnuts can be very oily and you may need to clean the seams of the parts with a bit of rubbing alcohol to help the glue to grip the shell.
