An Avenger brand 2-riser C-stand with a Rocky Mountain leg, 2.5" grip head and 40" grip arm. This stand extends to 10'. In film production, a C-stand (or Century stand) [1] [2] is primarily used to position light modifiers, such as silks, nets, or flags, in front of light sources. [3]
A bronze casting showing the sprue and risers. A riser, also known as a feeder, [1] is a reservoir built into a metal casting mold to prevent cavities due to shrinkage.Most metals are less dense as a liquid than as a solid so castings shrink upon cooling, which can leave a void at the last point to solidify.
Type Metal is also known, and used, for its ability to hold a true and sharp cast, and retain correct dimensions after cooling. Normally when making engineering cast parts the "method" is designed along with the pattern - being the riser size, number of risers, and location of risers.
The pattern is lifted from the sand, leaving a molding cavity. A passageway for metal to enter the mold, called a "gate", is then cut from the sprue hole to the void left by the pattern, and a runner is cut from the sand to allow metal to flow into the riser. The flask is then put back together, and metal can be poured into the mold.

Die casting is a metal casting process that is characterized by forcing molten metal under high pressure into a mold cavity. The mold cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mold during the process.
Film is commonly checked for broken sprocket holes before presentation, a process known as "spooling". Mechanical devices exist for this purpose, but the classic method is to place the finger and thumb of a gloved hand on the edges of the film, which is mounted on a winding bench, and to slowly run the film through the fingers, feeling for snags.
