After 3 double hernias and 11 broken fingers, finally managed to lift the 4 jaw chuck into place, only to find tightening the last nut the threads are damaged 
Didn't have the energy to take back off again
Anyone willing to speculate/know what the threads on the chuck studs will be?
As a starter for 10, was using a handy 7/16w spanner on the nuts
