Steam Bending Parameters

Calculate steaming time and minimum radius for steam bending

Formula

Min Radius = Thickness x Species Factor x Grain Factor | Steam Time = Thickness x 60 min | Form Radius = Desired x (1 - SpringBack%)

Frequently Asked Questions

How long should I steam wood?
The general rule is one hour of steaming per inch of thickness. For example, 3/4 inch stock needs about 45 minutes of steaming at 212 degrees F.
What is spring-back in steam bending?
Spring-back is the tendency of bent wood to partially straighten after it is removed from the form. Plan for about 10-20% spring-back by making the form radius tighter than desired.
