Explain how the panels should be stacked for casting when stacking panels of different heights in regards to their size and alignment.

• A. The bottom panels should be the largest
• B. The upper panels should be the same size or smaller
• C. The panels should be stacked randomly
• D. The order has no impact on casting

Answer: (B)

When stacking panels for casting, you want the stack to be stable and edges to line up neatly. Having the upper panels be the same size or smaller than the panels below ensures the stack sits flush without overhangs. This makes the stack easier to brace and lift, and it keeps the casting faces and joints aligned consistently as you build up height. If a larger panel sat on top, it could overhang the lower panel, causing instability, misalignment, and potential damage to the forms or casting surfaces. Keeping the sizes non-increasing as you go up maintains a solid, straight stack and predictable alignment for the final wall.
