Default Silver soldering shotgun barrel

Hi folks!

Looking at extending the magazine tube on an early [50's] Ithaca M37. Ithaca wants in the neighborhood of $450 just to change barrels, not including extended mag tube, so I'm looking at other option$.

The forward magazine lug is apparently silver soldered to barrel, so I'm thinking of de-soldering & moving it to the end of barrel. There's about 6" more real estate available so that would get me from current 4 shell capacity to 6 shells, better for defensive purposes.

I have some Harris Stay-Silv 15 #61035 which I seem to recall is about 900* melt, maybe lower. Strong stuff & up to the task. I'd have to do some shopping to find a suitable longer magazine tube.

Obviously Ithaca welded the lug on barrel when producing the gun so I can't really see any real negative effects. Thoughts on this?

Thanks!

For $450 you can get a brand new Ithaca 37 8-shot model.

Thanks!

I'm partial to the vintage guns. Thinking for 5 bucks worth of acetylene I can move that lug, lots cheaper. Just need to come up with a mag tube from somewhere.

I have done this before on a Mossberg. Didn't want to expose the barrel to naked torch flame and risk de-carburizing the barrel so I used an electric hot plate. First I warmed the barrel in a kitchen oven to avoid a large temperature gradient from the hot plate. Then set the hot plate to the required temp (which I don't remember what it was) and the lug popped right off.

I cleaned it, fluxed it, relocated and dabbed a few drops of Brownell's solder on, wiped off the excess and it was done to perfection.

It can be, and is done.

Contact Les Hovencamp and he can give you his take on it. He was the Head Gunsmith for Ithaca during the 1960's/70's.

His website is diamondgunsmithing.com. His phone number can be found there. He's a bit gruff, but knows his stuff.
