Year Published: 1945

Creator: Photo & Sound, Inc.

Description: This instructional film details the step-by-step process of creating a horizontal split pattern for casting a hollow bronze roller. It begins with analyzing the shop drawing and creating a precise layout using a shrinkage rule. The narrative covers selecting the appropriate stock, establishing the parting plane, securing the cope and drag halves with aligned dowels and screws, and turning the piece on a lathe. Special attention is given to crafting functional elements such as core prints, fillets, draft angles, and crusher strips. Finally, the film demonstrates the finishing process, which involves careful sanding and applying color-coded shellac—orange for the bronze body and black for the core prints—to prepare the pattern for the foundry.
