Subject : Flattening.. Am I flat enough?
Posted : 2021-11-02 5:03 PM

I have raw walnut that I'm veneering onto Baltic birch.

Attached is a photo. I used tamer on it twice and I'm still not necessarily impressed by its flatness, but I'm also not experienced. Is this what one should expect without using glues in the flattener?

Is it flat enough to work fine in a vacuum press?

Before the Doctor gets here, what was the flattening solution used and the steps used in flattening? Can't remember ever having to repeat the process.

I used Veneer Tamer
- wet the pieces (both sides)
- let them sit for 30 minutes
- put them between sheets of paper, used 1/4" MDF cauls and vacupressed them for 30 min
- removed wet paper, put in dry paper, vacupressed for another hour or so

First, I recommend changing the paper 6 times over two day, 3 the first day and 3 the second day. You want it fully dry. Second, there are a number of factors to, “is it flat enough”. One, is the size of the panel. Bigger the panel the flatter it needs to be. Two, are there seams or just one piece. If there are seams can you tape it together and the seam be held tight to the matching piece. There isn’t a simple formula its more of a feel. I no thats not a clear cut answer but its experience that will tell you if its flat enough. It was hard to get a good feel from your picture but it did seem a bit wavy, especially for walnut.

Thanks. No worries, I figured I need to put my time in to know. I went for it. 5 pcs with 4 seams. It looks good. No bubbles. Seams look tight.

I don't have any complaints with how it turned out.
