Segmented wood patterns involve using different types of woods joined together to create a single wood vessel. The process can be used to create a variety of wooden objects ranging from vases to boxes. Creating a segmented wood pattern requires that you join the wood segments securely together, gluing them into place prior to assembling the complete wooden object. While the process is time consuming, given drying time, once the segments are joined, you can create objects that may be used as functional works of art.
Lay the wood segments cut into wedges onto a clean flat surface that the PVA glue will not stick to, such as formica or metamine. Place a thin layer of glue onto the side edges of each piece of wood before placing it against another segment. Place the wedges against each other, applying pressure on the glued joints to start the glue setting process. Glue the segments so that the wider portion of the wedge is to the outside of the ring with the narrow side of the wedge forming the inner diameter of the ring. Make sure that the outer and inner diameters are even, forming circles.
Clamp the ring of segmented wood with a stainless steel hose clamp placed around the entire outside diameter of the ring, pressing the wedges towards the center. You clamp the ring in order to hold it in place as you level it, and to maintain the ring's shape as the glue sets. Place the clamp around the wood ring so that it holds the ring of segmented wood wedges loosely but securely. Test the clamped ring to determine that each segment can still move slightly within the clamp by moving a random segment up and down in the ring.
With the ring on a flat surface, tap the top of each piece of segmented wood in the clamped ring with a rubber headed mallet so that it is level, and then tighten the hose clamp around the outside of the ring until the segments can no longer move.
Remove any excess glue from the ring of segmented wood and then wait 18 to 24 hours for the pieces to dry.
Remove the hose clamp and level the face of the ring. Level the ring by using a belt sander on the face of the ring. Move the ring constantly on the sander to remove dips and mounds on the face of the ring you'll place against another ring. Check with calipers to ensure uniform thickness throughout the ring.
Place the wood base of your project onto the level surface of a piece of waste wood block. Glue the wood base to the block to secure the base in place and to provide a stable platform for adding the wood segment rings to the base as you build up the sides of your vase or bowl.
Center the first segmented ring onto the base and glue it in place, clamping it securely to the base piece. Allow it to dry and then level the top of the ring where it will connect with the next segmented ring piece.
Repeat the gluing process until you've connected all the ring segments.
