I purchased plans from FWW (SU24) for this chair.
It's my first attempt at steam bending parts. From what I read, it's important to strap clamp the ends to avoid stretching/breaking on the outside curve. However, Galbert's plans do not call for that. The bends are relatively small, and the spindles are only 5/8", so I can understand that. However, the back posts are 1 1/2" thick.
What's your general rule of thumb for this kind of thing?
