ABSTRACT:
A draw tube adaptor for insertion into the draw tube of a lathe. The draw tube adaptor includes a sleeve, and carried within the sleeve are a series of bushings spaced apart from one another. The bushings have bores sized to accommodate the diameter of the stock to be worked, and are maintained in a spaced apart relationship by cylindrical spacers carried within the sleeve. These spacers space the bushings at desired locations throughout the length of the sleeve. A cap arrangement is provided on the sleeve to retain the cylindrical spacers and bushings within the sleeve.
