5C Collet Adapter with the "4-3/4" Morse taper.
This is for all the older R series lathes with 1-7/16 or 1-1/2 spindle bores with either L-00 or 2.375-8 spindle nose. For most Sheldon lathes made before serial number 26000 give or take. Will not work with the later R series lathes with 2-1/4 spindle bores.
Dimensions were very accurately measured and recorded as drawn. The dimensions for the 5C collet register were taken from a Hardinge Brothers drawing from the internet.
