Disston saw vice needs welding or brazing
New into the metalworking site.
I need help or advice.
I recently bought a small Disston saw vice.
I wanted to pad the jaws with some thin cork, so I pulled it apart.
Discovered a previously brazed pivoting point had broken again.
See photos.
Now I need it brazed/welded again. Brazing on cast iron or is there new welding products around.
Or looking at the break, any suggestions on a repair.
I'd hate to chuck this out to scrap.
I'm in the Newcastle area.
Thanks in advance.

Personally I would braze it again, only this time it needs to be done correctly, edges need to be beveled and I believe it was not at the right temperature (bearing in mid I am looking at photo) some one who knows how to braze properly could do it.
Not a complicated job just needs to done right.

I think, if it was mine, rather than trying to braze the bit back on, I'd build the ear up with braze then redrill it.
You'll be looking for someone with specific brazing experience. And the gear. I would suspect not many welders would these days.
A men's shed who are into metal work maybe?

Amen to to the opinion and advice offered by China. Try to ensure the brazing is carried out using manganese bronze filler rod. Perhaps Grahame Collins might care to offer further suggestions.
Good luck in finding an "old school" welder for the job, at least your location in Newcastle should provide a pool of expertise and experience, given the district's industrial history.

Thanks for the replies. After a few phone calls and lots of questions.
I have taken it to a place in Heatherbrae. The manager said he couldn't charge me for it as a single job, but as one of his welders was about to do some brazing, he'd do it in that batch. They were fascinated with what it was, especially when I explained that it was an antique woodworking saw vice. And not likely to be able to get another one
Seemed to know what was required, preheat, temp control cool down etc. He talked to the welder who said it'd be an easy job. So I'm confident it'll be done well.
Cost... 6 pack of JD and coke.
Waiting with fingers crossed.
