Abstract
There is disclosed a chuck assembly for internally holding a hollow substrate having an open end including: (a) a body including an end section having a width narrower than that of the inner width of the substrate to permit insertion of the end section through the substrate open end into the substrate interior; and (b) a compressible spring coiled around a portion of the end section, wherein prior to compression the spring has an outer width larger than that of the inner width of the substrate, wherein upon insertion of the end section of the body into the substrate the spring is compressed by contact with the substrate inner surface resulting in the chuck assembly holding the substrate by the force generated against the substrate inner surface by the spring in opposition to the compression.
