- Cut a diamond out of the damaged veneer with the longer axis along the grain of the veneer.
Am I on the right track? Any better ideas? Forum Responses
I agree with John. Cutting the patch to fit the exact size will make a better-looking job. Everything else sounds OK. Locke Wilde, forum moderator I would make two router jigs, male and female, where the male jig easily fits the female jig. Use the router with an inlay bit and the female jig, to take the existing veneer out. Then use the male jig for cutting the new veneer.

1. Cut a diamond shape around the damaged area with the long axis of the diamond in the same direction of the grain. Be sure to cut all the way through the face veneer. Carefully pry up the diamond without damaging the crossbanding or veneer core. If this happens they will have to be repaired or any irregularities will telegraph through the new patch. 2. Make a pattern of the diamond; You do this by making a rubbing of the area. Take a piece of paper 1 or 2 inches larger than the diamond recess and tape it down over the area. Shade over the area with a soft lead pencil. Remove rubbing and carefully cut out diamond. 3. Glue diamond to clear plexiglass with spray type adhisive. Carefully cut out the diamond with a jewelers or coping saw. (Note: do not use a scroll saw because it creates too much heat, which melts the plexiglass.) Cut the diamond template a little oversize and file the edges to a perfect tight fit, checking often to make sure you don't over-adjust the template fit. Remove the paper pattern from the plexi-glass template with paint thinner. 4. Place the template over the veneer. Move it around to locate the correct grain direction and pattern to match the piece being repaired. When satisfied with the match, carefully cut it out. 5. You can glue the patch using woodworkers glue or aliphatic resin. Apply wax paper between a flat hardwood caul and then clamp. The method I prefer is to apply the aliphatic resin to both surfaces and let the glue completey cure. Once cured, the diamond patch can be set into the recess and bonded using an iron on medium setting. (Note: mask around the recess prior to applying the glue to prevent glue stain on surrounding areas.) 6. Lightly hand sand patch using a block and finish.
