Using Spotted Gum I think handplaning would be mighty difficult because it works like stone. Another technique I've used before is sawing accurately to depth cuts to define the foil. These are a guide to shaping the waste off. Cutting these on alternate sides provides accurate symmetry. A third method used with plywood is to simply sand to reveal sequential layers of ply,at various depths. This looks super cool and is accurate because you can gauge the depth quite easily.

The Spotted Gum was true to form but will varn
