General 350 Table Saw - Herb - 10-09-2019

The top on my saw has a crack in it. It is about 13/16" right of the throat plate opening. The crack is not al the way through and it is less noticalbe at the back than the front.

The saw itself is at least 20 yrs old, however, the top was replaced at least 10 yrs ago due to it warpping.  The crack at the widest point is about 1/16" wide and deep and would trying to fill it with J.B. Weld keep the crack from espandinig?

Thank you for your help,

I would drill a small hole in each end of the crack to try to keep it from spreading.
Then fill the crack.

How deep do you drill?

While I have heard about drilling holes at the beginning and end of a cast iron crack to keep it from spreading,  I have never heard if you drill completely through or to a certain, unspecified depth.....

All the way through. It stops the crack from propagating further.

Then see why the crack started in the first place. Lack of support underneath or stress points where bolts connect and possibly "pulled" a section that didn't line up right.
If the top was replaced once, that may mean there is a problem with stress somewhere. A washer missing, a bad cast or fit that needs shimming....
