Another happy customer of our DVDs asks a question about veneering:
Hi David, my wife bought me your DVD on hammer veneering a while ago which I enjoyed immensely and also learned a great deal from. To date I’ve been reasonably successful in managed to veneer some small panels with stringing and cross-banding. Easier when you know how! However, the whole process got me thinking on why panels are cross-banded like you demonstrate, or at all, for that matter? I’d always been told that its to give some sort of structural support to the central veneer.
What you are seeing is what is called “telegraphing through” It is exactly what you say the edge lipping is moving. There are a few things we do to help avoid this.
1. Most important keep the lipping as small as you can 10 by 20 on a 10mm panel is big we would aim to use 10mm by 5mm
2. You need to have really well dried stuff both the panel and the lipping well conditioned to the workshop . We take a moisture reading every day for a couple of weeks if we can . When it stops moving its a good un
3. I always try to hot glue veneer both sides in one session to avoid warpage and stress on one side . This may be a part of it as well.
4. Sycamore and maple are very translucent we often put two layers of these veneers laid one on top of the other to cover the line where the lipping shows up.
Its a pain !
Hope this helps
