ABSTRACT:
An apparatus as disclosed for making concrete forms for making stairs. A substantially planar member has a riser end and a pivot end substantially opposite the riser end and has first and second. A pivot point rotatably fixes the pivoting end to a stinger so that the riser end can pivot with respect to the pivot end. A riser support member is mounted perpendicular to the planar member adjacent the riser end and extends to each side of the planar member. A kneeboard support may be placed on both sides of the planar member so that a kneeboard may be placed between one apparatus and a corresponding apparatus on the other side of the stairs. A scale may be provided for positioning the apparatus with respect to the stringer to facilitate mounting subsequent apparatus to a given stringer. The riser support member may be slanted to provide a constant toe-in or kickback.
