How much weight do you think is ok for for a drill press before thre is
any bending in table support?


If you put a one microgram weight on your table there will be deflection. It
just won't be very big. If you put more weight on then there will be more
deflection. It is impossible to give numbers knowing nothing about your machine.

If that's a problem, it should be possible to use some sort of column jack to
greatly bolster it against stiffening.

Drill presses aren't very good for precision work. If you need better than 1/32"
accuracy you're in trouble. That's what milling machines are for.
