tried those methods but didnt work

so i had to resort to hacking the entire chuck plastic assembly, spring and bearing reatining plate off

this left a bear chuck and a shaft which would slide out the gear bx just a case then of getting good grip in vice and twisting with mole grips

before couldn't get any hold on the shaft

2hrs, 8 dremel discs anumber of scrapped knuckles and they are done

:twisted:
