Projecting 16mm Film with Large Reels

J. S. Chandler

The concept of “effective weight” is developed as a means of rating reels according to their relative film-damaging potential. Useful relationships between size, capacity, stiffness, weight, and effective weight are presented for all 16mm reel sizes. The importance of a large ratio of core diameter to outside diameter for the reel is stressed. Some standardization proposals and design features of the projector for use with large reels are suggested.
