ABSTRACT:
A solder jig for use in constructing "stained glass" ornaments and the like having panels disposed at selected angles with respect to one another. The jig is useful in constructing ornaments by either the lead came method, or the Tiffany (copper foil) method. The jig includes a base having a flat top surface and support legs. The base provides a pair of threaded holes receiving adjustment bolts. Locking wing nuts are provided on the adjustment bolts. The heads of the adjustment bolts are equipped with bar-shaped supports. Each support includes a generally flat horizontally extending portion and a generally flat portion making an angle of approximately 140.degree. with the horizontal portion. The base also provides locating pins which protrude upwardly generally vertically from the top surface of the base. A pair of work surface providing members are notched to engage the locating pins and rest upon the supports. The adjacent edges of the work surface providing members intersect at a predetermined, selectively variable angle which corresponds to the angle to be formed between two panels of the ornament. This structure thereby holds pairs of such panels in predetermined angular orientations with respect to one another while they are joined, e.g., by soldering the copper foil or lead came provided around their perimeters.
