After reviewing my dilemma with the frame and drilling out the hand slot.
Is it possible to remove the arbor from my frame and drill from the front of the frame?
OR,
should I attempt to drill the .607 from the bottom of the frame and leave the arbor in place?
My father-in-law (retired master tool and die maker) suggested that I remove the arbor and drill from the face. Either way, he said that it will be a lot of work and GO SLOW.
I'm still evaluating the best way for me to work through this..
Thanks for your thoughts.
