It looks like you lost the upper table Gibs. See page 33 of your G0593 owners manual, or do a google search for it. The table gibs help eliminate excessive play in the table. Unfortunately there are no gibs on the back side. I might suggest drilling and tapping one or two on the backside, but lower than opposite the break.

To me, it looks like the gibs had/were over-tightened at some time, to the point of breaking off the section that you have. The backside looks accessible, creating a couple of gibs on the backside looks possible. Just my 2-cents.

Update—You can probably get the set screws ans nuts from Grizzly. Parts:
  • 51-5 Part #PSS01 – Set Screw 5/16-18×1
  • 51-6 Part #PN02 – Hex Nut 5/16-18
