Subject : What to use to fill Walnut burl voids?

I have some gorgeous walnut burl veneer that I will be using on some flat panels. It has some small voids where there was some bark inclusion. What is the best way to fill these? I have used tinted epoxy for other veneers but they were thicker and I didnt worry about sand through. I am concerned about that with this. Thanks for your help.

One option would be to again use tinted epoxy. After curing, you could carefully pare away some of the excess epoxy with a sharp chisel or sand close. If you're worried about the thinness of the veneer, after getting the epoxy close use a cabinet scraper to level the epoxy with the veneer.

Another option would be to use some scrap walnut burl to fill the defects. Cut a slightly larger piece of about the same color. If filling before pressing the veneer, cover the glue side of the hole with a bit of blue masking tape, but a drop of white or yellow PVA on the tape, lay the veneer patch over the hole and gently pound approximately level with the surrounding veneer. Sand with a bit of say 150 grit to remove any excess glue from the show side and fill any small gaps with sanding dust. After the glue cures, remove the masking tape from the glue side.

Of if the defect is smaller than say 1/8" diameter, put a piece of blue masking tape on the glue side, then stab the immediate area around the defect with the corner of a chisel a number of times, to spread out the veneeer around the defect. Again a dab of PVA over the area and sand.

Both of these techniques are well demonstrated on "Decorative Veneering" by Paul Schurch, www.schurchwoodworking.com. Mr. Schurch's two videos are as excellent as Mr. Keil's, and I would recommend all four.

Martin,

What size would you say are the largest voids in your walnut burl?

I have one bark inclusion on the edge that is Approx. 1/2" X 2". There are a few more but they are much smaller.

Martin,

At that size I would cut and fit a piece of the same veneer. When they are much smaller I will mix up some of the Unibond 800 to match the veneer as close as possible and fill the voids using a putty knife. Also a good wood filler in the same color range works well. I always have some colored pencils to touch the area up after I've scraped and sanded. A penciled in grain line can really disguise a patch job.

Darryl

To "inlay" a patch that size, you might try what Mr. Schurch refers to as a "sqiggle cut" and demonstrates on "Decorative Veneering" if you have a scroll saw. Lay the patch over the defect, so that the patch extends beyond at least an inch in all directions. Cut a meandering seam (like a continuous sine curve, if you remember your geometry) on the overlapping area. The back and forth curved seam is more likely to disappear into the burl pattern than a straight seam.

I hadn't thought of using the Unibond for a filler. I bet that works great for the smaller stuff. I think I will also try the sqiggle cut idea somewhat modified. The burl I am using is 22" X 50". To big to handle on the scroll saw I think. Thank you for your help.

Martin
