ABSTRACT:
A tool for positioning a plurality of templates with respect to a curved rail includes a flexible spine that carries a plurality of templates. Each of the templates defines an opening adapted to guide a cutting tool to form a picket hole in the rail. The templates are evenly spaced along the longitudinal direction of the flexible spine so that the picket holes are evenly spaced when cut. A clamp may be associated with each template to hold the tool with respect to the rail.
