Veneer Seam Showing After Finishing12/29
I taped together 1/8" thick pieces of lacewood that I cut at the bandsaw. Shot the edges at the tablesaw. Just finished putting on the lacquer and the seams are showing. Everything looked tight before I glued it down, even checked with a wipe of naptha. What would you guys do? The pores are open and I wasn't going to fill. I would appreciate your suggestions. Thanks.
Your veneer is very thick, that makes it hard to pull the edges together. Even a .001" gap looks like The Grand Canyon when you put finish on.
What we do is to put making tape on each side of the joint(s) that are open. Then take a little finish between the tape gap (over the veneer gap) using a pointed artist brush. We call it drip filling. After the finish hardens, carefully scrape the high spots, then skuff sand and re shoot the panel. If you are doing an 'open pore' finish you need to be very careful not to fill the grain, just the gap. If you are doing a full fill finish, it's less of and issue.
Let us know how that works out.
1/8" is really considered wood, not veneer. It may have dried out, or shrank from heat from a furnace. 3/32" is what I start with before sanding. Did you put glue in the joint, or just the face? You are really working with thin boards here.
edge glue the pcs together. use packaging tape like a hinge. glue edge and close the hinge and when glue drys you have a sheet of veneer. make sure your cross grain with substrate and back has same veneer so your balanced on both sides. we use a router and straight edge a bunch of pcs at once when doing this.
I use a small luer-lock bottle/needle to run a bead of finish along the seam.
I am glad you found a resolution to your problem.
