Welding cast is pretty easy in the hands of expeirience , but for the beginners I would recommend brazing. If you mess up you can always clean it up and start over. Welding ... not so easy to re-do . But I personally like to stick weld the stuff. DC reverse polarity with a good nickel rod and it welds like a dream.

Thanks for all the nice comments. I do braze alot with silver but I had never used brass before or tackled something this massive. I was at the limits of the torch using propane. I would have used acetylene but all I have are the small mc tanks and they were empty. Besides that stuff has gotten too expensive to experiment with.

 

I had considered welding and looked at several different process to do it, mig and stick. But I have been using a torch for over 10 years, welding less than a few hours under a helmet. Thats why I opted for brazing. After doing alot of reading I am pretty sure the braze will out last me.

 

I would like to heat it back up and reflow the braze were the voids are that I can see, but I know that if i do I will have to start over. I might try just capping that one area some time.

 

All in all it wasnt as bad as I thought it was going to be. Now I can pick up more broken vises.

Sure looks good enough for a repair, and yep, that repair will 'prolly outlast  us both . Good work with the torches :-)

Unless the voids are a lot bigger than seen in the photos you will probably be long gone before that repair fails. Just don't use it for an anvil and you will be fine. Nice job!
