The Cushman 12" direct mount solid steel 4 jaw would be my first choice and with an ER40 collet adapter would handle most any job on the 1941, 14 X 30 Axelson gear head lathe. Because of the age of the machine the spindle was not ground in place resulting in about .0004" spindle nose run out causing .003" run out on the rim of the 12" chuck that should be easily corrected with a file and perhaps a scraper on the flat mounting face of the chuck in the next video.
