loose vice wrench.

[welder]

i have a mill vice probably from china that the square wrench fits very loosely by 1/16 "gap. it appears to be casted of maybe iron. i would like to fill in the excess play. i have a mig and gas welding equipment. i do not want to crack it or make it brittle. what do you think. oxy acetalene steel rod,brazing rod or mig. thanks

Braze or silver-solder in some gauge plate or shim stock? You can get it in various thicknesses, and it'll be harder and wear better than cast iron.

You have a mill. Make yourself a properly-fitting wrench.

No. The manufacturer all ready made it brittle for you.

If the square is big enough, change it to a 3/4" hex and get you a common handle to use with the vise. There are a couple of sizes of the hex handles out there if 3/4" is too big, go the next size smaller. Last resort, make a new screw and cut a hex on it to fit a common handle and do away with the square handle.

Or drill and tap a set screw from the side to tighten up against the handle,adjust for the slop.something like this:

Hi Welder,
as long as you let the casting cool slowly you should be fine- you're only getting it hot enough to braze
