Abstract: An on-site fabrication method has been devised for compound bending of laminated wooden beam members into a handrail for curved or spiral stairways in which upstanding supports are positioned at intervals along the path of intended curvature on the stairway, the strips are assembled together in juxtaposed relation to one another and retained by leveling brackets on the support members whereby to prevent twisting of the beam members when a lateral force is applied, clamping the beam members together against each support member and permitting the beam members to be cured into a unitary rail section.
