Another discovery about the unusual compound table:
When I started to clean the 20 lb. bronze trough/top that came on the above table, I spilled a few drops of WD40 into the trough. They immediately started to run toward the drain. No matter where I squirted a few drops in the trough, they always made their way to the drain.
As it turns out the trough has a built-in slope that I never noticed when dismantling the thing to adapt it for my drill press. All the effort to manufacture a trough like this, coupled with the hand scraped ways, and six gib adjustment screws on each axis with only 4" of travel makes me all the more curious about what this might possibly have been intended for originally.
