Having a bit look at the Father in-laws shot gun and barrels seem to be splitting apart? Looks like they are solider joined together. Got a feeling it might be worth my than the gun to fix. It a Boito?
Cooper wrote:Thanks blade. I was notsure how they would have joined them together. I was thinking it might be some sort of cold solder process. I’d be worried about using too much Heat and the barrel trying to fall apart or something.

I always thought of solder as a weak joint .. definitely thought it wasn’t water proof either ... do they have “stronger” solder joint than what they use in electronics? (Curious)
What are they doing here: (link to video below)cadet wrote:Either way, a Boito is unlikely to be worth a decent 'smith's hourly rate to fix. Might be an ok DIY project though.
I like this video showing the work to get barrels aligned ...
Fast forward to 10:14 (to 11:50)

Hope they put that much effort into mine

It is really hard to solder something like that as you need quite a bit of heat as the barrels just heat sink all the heat away. What this means is that it need to be held firmly in place when you start as it will all go molten at the same time.
The Solder that is harder than the normal lead tin mixtures are when you add some Silver. This is known surprisingly as Silver Solder. Much higher melting temp and much stronger.
