Handle

I am trying to intersect two cylinders on the outer side of the radius and was wondering if anyone has a similar program they could share. Please review attached file and take note of the two dimensions circled in red, any advise would be appreciated. Let me know if you require additional information, I will be happy to assist. My best guess... I would need separate alignments to project lines to the out side of each cylinder and then intersect the lines? How do I project a line to the outside of the cylinder radius?
