Table legs with metal threaded inserts

I'm adding table legs to an old top. I'm planning to put hanger bolts in the legs and threaded inserts in the top. The legs and top are oak.

My concern is how perfectly straight do I need to drill to install the hanger bolt and the threaded insert? If it's off by a degree or two, will it pull itself flat when I tighten it?

I have a drill press but it's not tall enough to drill into the end of a table leg. I can probably get the table top positioned under the drill press, but is that necessary? Hints and comments are welcome.

The old table top has short stubby legs, and I'm trying to extend them with the hanger bolts and threaded inserts. There will be a shelf between the legs to add structural support. I know that another solution would be to rebuild the apron with integral legs and proper glued wood joints.

not sure I completely understand your proposal - but . . .

threaded insert at top
hanger bolt at bottom
both right handed thread....
there's no way to tighten them together. tightening the upper loosens the lower, & visa versa
to use top insert and bottom insert/hanger bolt you need a "turnbuckle" arrangement which one side has left handed threads.

is the theory to add space between the carcass of the short stubby legs and the table top?
or add space to the bottom of the legs?

If you are doing what I have tried to illustrate there should be no problem if the hanger bolt is not exactly straight within a few degrees, as the bottom leg is tightened the top of the leg will tend to align it.
