material
Based on our tests, MDF seems to work best because it is uniform
and flexible. Other types of manufactured panels also work but
the irregularities of standard lumber
will lead to complications. You can apply veneer to a curved panel to simulate hardwood.
size of panel
There isn't a size restriction, but larger panels will be harder to
cut and clamp. Also, the larger the panel, the more help you will need for the gluing/clamping step.
thickness of panel and kerf dimensions
We used 3/4" (19mm) thick MDF so the completed curved panel was 1.5" (38mm) thick.
You can use a thinner panel but you may have to change the kerf dimensions. The thickness of the material
left at the bottom of the kerf remains critical and 1/32" (1mm) is a good guideline. Remember
that the material that remains between the kerfs serve as the gluing surface and therefore
cannot be undersized. You can use thinner table saw blades as well. It is best to experiment for
your particular situation. |
