Heck, there are probably enough of us on here with full size drill presses that you could borrow time on one of them!
To answer your question though, I have a shopfox benchtop DP and I have done things that are longer that the head-base gap. I bolted mine down, but clamps should work. I rotated the head to stick out off of the bench and I used the edge of the bench to clamp my workpiece to hold it steady while I drilled. Worked fine.
