Aremco epoxy even though I don't know the cost? **But..... **I would wait till you hear back from Redmond before I did anything and wouldn't be a bad idea to just call Steel City customer service to see what there take is....

I would just leave it alone with the exception of taking any rough edge off it there is one if I went that route. **Again.. But..** a valid point has been brought up about a possible stress to cast iron in the table. So.. even if you do repair, I would get with Steel City and have them make a note of it in their service files with your serial number for future reference just in case the cast iron was stressed from a hard hit which it looks as if it took somewhere along the line.

Again.. IMO, at this point just wait for Redmond or call Steel City!
BTW.. where are you located?
