Seven Steps to Veneering Success

I aking your own veneered panels adds a new dimension to your woodworking design capabilities, and it's fun to do. The wood-I working techniques used for veneering are similar to those used with solid wood. Sawing, jointing, gluing, clamping, trimming and sanding are all familiar woodworking tasks. In this case, narrow sheets of veneer are edge joined to make wider sheets that are then applied to a substrate (the core the veneer is glued to). I prefer MDF for my substrates since it's smooth, flat and very stable. I find it easiest to use wood glue, cauls (flat panels that spread the clamp pressure) and clamps. Or you can build and use the simple veneer press shown on page 70. For small veneered panels like these, I use slow-setting yellow glue. Getting the glue on fast enough is always a challenge, so glue up one panel at a time, and ask for some help if you can.

You must make "balanced" panels (a core with veneer on both faces in this case), and you need to put both pieces of veneer on the core at the same time. Oversize the veneer pieces so you can cut them to their finished sizes after the veneers are glued to the substrates. £

STEP 4: Flip the joined sheets over and apply a piece of gummed backed veneer tape down the joint. Lay a scrap flat panel over the taped sheet so it dries flat. Remove the masking tape.

STEP 5: Lay the sheet with the tape side down over the edge of your table. Open and glue the joint. Lay the sheet flat again to close the joint and place sticks aside the joint to hold it flat.

STEP 6: Assemble the glue-up "sandwich" as shown in the exploded photo (above left). Using a narrow paint roller, apply a moderate coat of slow-setting glue to both sides of the core and to each veneer.

STEP 7: The glue-up requires a few deep-reach clamps. They are very important because the clamping pressure needs to be applied to the center first so no excess glue gets trapped there. Let the glue cure 24 hours before removing the clamps and trimming the panels to their finished sizes.
