Only 4" long ? Rod, few nuts, vice and a file.

Well, yeah, but I think the problem w/ hand filing is that in order to
get a profile that has enough clearance he's going to be filing for a
long time (TM)...

It's only 4" long. That's pretty quick work with most files. Worst case
scenario, he uses an grinder and fine tunes it with a really fine file. I'm
thinking 30 minutes at best. But, I do like the drill press depth rod idea.
It's beyond me why someone would need one of those on a drill press anyway.
