Troyke 12" Rotary Table

[race5050]

I bought a Troyke 12" (BH-12) Rotary Table thinking I got a decent deal on it. After lubing it with machine oil, I was happy to see that it rotates very smoothly and works great. However, I then noticed that all of the oil I added had seeped out of the bottom. I flipped it over to see what was up and found a big square hole underneath that appears to be too perfect for a hack job. It seems to have served a purpose but I'm not sure what for. Maybe to connect to a DC motor and gears to run the rotary table? Anyone ever see something like this that may be able to provide some insight? I'm not sure how I will use the table and keep it oiled with that big hole there. Any input is welcomed.
Thank You.

Troyke said it was likely field modified. Doesnt bother me or affect operation. Just a little messy when i lube it. Good enough for a home machinist.

You could make a cover for the hole.
