Gary,

How big are the voids?

Sincerely
Darryl Keil

Darryl, the voids are about pencil diameter and smaller. I'm actually veneering the boards myself to about 1/8 inch. Plywood will be the substrate.

Paul Schurch demonstrates several ways to fill voids on his excellent video on decorative veneering. It is available through www.schurchwoodwork.com. His video is an excellent companion to the two by Darryl Keil, and there is very little overlap between the three.

Come on guys, give me a hand here. What home made mixture or commercial product do you think will work best to fill voids in mappa? I don't want to mess this up.

When working with mesquite I use epoxy and tint it black. I don't know why you couldn't do the same with the burl and tint the epoxy whatever color you want. After it drys I take my beltsander and sand off all the excess. Steve

1. Veneer punches make irregular holes in different approximate diameters. Irregular presumably so "plug" doesn't show. One old post somewhere talked of cutting off 2" piece of electrical conduit. Remove metal from inside and/or outside at one end so a knife edge all the way around. Optionally, bash with hammer so oblong or some such. Punch out around a void. Punch plug in matching scrap veneer. Insert the plug in the hole, cover with piece of veneer tape.

2. Cut out piece of matching scrap about same size as void. Working from glue side, press into the void, trimming if needed. If slightly larger, bash together with end of chisel. If slightly smaller, stab a number of times with corner of chisel to expand the patch. Smear a drop of PVA glue over patch and edges, scuff (glue side) with 80 grit to work some sanding dust into the glue and any voids.

3. Fill with putty after gluing to substrate, hide with shellac and tinted powders. See "Great Wood Finishes" by Jeff Jewitt.

4. Epoxy tinted black is also good trick, works very well with voids in cherry.

If you continue to work with burl veneer, the problem will arise again and again. The Schurch video is well worth the money, as are the Keil videos.

Gary,

Similar to Steve's suggestion with epoxy, if you are using Unibond 800 you can tint it with analine dyes to match the color of your veneer. When you press the veneer the extra glue will fill up the holes.

Sincerely
Darryl Keil

no one has mentioned mixing matching sawdust with epoxy....that's another option instead of trying to get a perfect match with dyes.
