I built a pretty hefty add-on drill press table and it is heavy.

The weight doesn't really bother me, but the lack of clearance to get
to the crank to raise and lower it does. I'm going to modify the table
to give me more clearance back there.

I don't have the tools to make a table that would fit in the existing
trunion accurately and don't really see any advantage to replacing it.
