Mild flips, I use dry heat, but for real recurving I prefer steam. After steaming in the curves, i let it alone for three days. I have not experienced many problems with using steam alone. I never thought about dry heating it after steaming... I have found that with white woods I need to leave them clamped to the form till they are completely cool, but with osage, the curve seems to be set in and permanent after just a few minutes.
