I just picked up a 1939 ULH basket case . The motor has good condition matching number cases.
I will be lapping main brg. case races , To do this , do I cut out the lugs and replace the races with 40 and later races? Or, could I just set up on a mill and cut the lugs just below the race surface and then lap races? I searched the archives ,and I don`t quite understand .
Thanks in advance.
