Curved and radius millwork are commonplace on leaded glass windows. Several methods including; kerf cut, laminating and steam bending can be used to fabricate new or replacement components. Radius stop molding adjacent to the round leaded panel (right photo) was fabricated using the steam bending process illustrated below. Good quality moldings can be removed and reinstalled without damage saving resources during future maintenance.
Quarter sawn White Oak blanks on drying racks are periodically checked for moisture content after being steamed and bent to a specific shape.
When a satisfactory moisture level is attained the blanks are removed from the racks ready for milling.
Sizing, profiles and other details are machined into the Oak stock after being cut from the curved blank.
Moisture levels are an important consideration throughout the fabrication process including application of a finish. Quality steam bent components should hold their shape indefinitely.
