I just completed a much needed project. My Craftsman / Atlas 618 didn't come with a drill chuck when I bought it. Luckily I had a 1/4" drill chuck on a MT #1 shank that had been my great grandfather's. Unfortunately, at some point in it's long history it must have been in a crash because the shank is bent. I usually could get around the bend by clocking it, but this became very annoying. I have a small Delta 8" drill press that I don't use much with a 1/2" JT #33 chuck on it. So I decided to try my hand and making an arbor.
First - I found a piece of scrap 5/8 (JT #33 Large Dia. is 0.624) bar stock that looked long enough.
I faced and center drilled both ends and it wound up being 3.289 in length.
(I didn't expect to get it right the first time so I just faced the bar and wound up with length.)
Second - I put together a simple spread sheet to calculate the Setover. (Attachment #1)
Third - I set up my indicator and moved the tailstock over 0.1045. (Attachments #2 & #3)
Fourth - I marked off 1.000 and placed the bar in between centers and began my cuts. (Attachment #4)
This all I can attach here so I will continue in a reply box.
