I bought a used Fisher Scientific overhead lab mixer. The mixer motor is a rebranded Bodine gear motor with a direct drive output shaft and a gear reduced output shaft. The mixer came without a drill chuck.
Each shaft is .315 "inch (5/16") diameter by 1" L . I want to mount a 3/8 or so drill chuck on the direct drive shaft without adding too much length.
Originally these mixers were equipped with a shaft mounted chuck held in place with setscrews.
I don't know what the chucks are called so my searches come up with all kinds of taper mounts. Does anyone know what these chucks are called and where I might buy one.
The chuck needsto be hobby grade.
Thanks in advance
