Hello all. I was stupid and overtightened the threaded pommel of my Hanwei Basket Hilt Backsword and managed to snap the threaded part off. I was just wondering if it would be possible to get it welded or repaired without ruining the temper of the blade, or would I have to completely re-hilt the sword. Thank you, and sorry if I made any mistakes. I new here. I'd add pictures but I dunno how.

Yeah, should be ok. I mean, if it's through hardened, you'll ruin the temper near the screw, but that shouldn't matter too much. I'm surprised it broke though. Find a welding shop nearby, should be able to weld it for you in a jiffy. An alternative would be to glue it on with JB weld (make sure to sand each side with coarse sandpaper and clamp it). It will be more likely to break there again though, so be careful in the future not to over tighten.

Adding piics sbg-sword-forum.forums.net/post/932297/thread with pictures sbg-sword-forum.forums.net/post/932195/thread Welding is definately possible. There are a few precautions you can take: Work fast, use someone who is good at welding and put something big and metal (like a vise or clamping some metal blocks) on the tang to limit the heat from spreading too far. This metal will act as thermal mass, (hopefully) sucking away enough heat so it can't spread as far. Don't put it too close or the weld will be too cold. As larason2 said though, it should not matter that much. At least as long as the annealed portion doesn't see lots of lateral force. If it was softened right where pommel and wood of the grip meet you might be more likely to bend than if it was softer a bit inside the pommel. Since you are unlikely to hold a backsword at the pommel this would not be that bad.
To be honest, would not trust JB weld with this.

Thank you, and sorry if I made any mistakes. I new here. I'd add pictures but I dunno how. The very same thing happened to me. Welding is sadly not within my skill set, so I ground the blade down (or up) a bit to recover some tang length, softened the tang with a torch, reshaped it into a cylinder, and cut in new threads. Removing the tassle gave me another eighth inch. Its also possible to flatten the bun-top of the pommel. Now, I soften all my threaded sword tangs. The danger then can be stripping the threads; just don't crank it down, and use Loc-Tite. That threading breaking off led me to the gloriously-fun hobby of sword modification and several new shop skills. Here's to your own journey.

I bought a torque wrench and looked around for a bit, for small 6mm threads on Hanwei/Tinker the max torque is about 7ft*lbs, I have done 6 and that's as high as I feel safe to do and the blade rings nicely.
Cutting down IMHO is more work and at least as work intensive as welding, also needs tools and expertise. I think a good welding person is pretty easy to come by nowdayys - and some even do that stuff because they want to try.

Thank you all for your help! I'll look around for a decent welder in my area and hopefully be back in business.

I agree JB weld is not as reliable in this situation as a good weld. But if it falls off, you can still just get it welded. If you sand the faces and it's clamped for long enough you can get a pretty good hold with JB weld. That's why modern car manufacturers actually use this kind of stuff for a lot of the joints on car frames. If you don't want the risk though, then get someone to weld it!

Got her welded and now we're back in business. Thank you all again for being so accommodating!

Nice, don't worry about your weld it's not uncommon to lower the hardness of the tang for durability anyway.

I am surprised the threaded extension snapped off the tang of a Hanwei Basket Hilt backsword. On mine the threaded part appears to be machined out of the tang itself. There is no indication or discoloration showing that it was welded on like a cheap rat tail tang would be. I changed the pommel nut on mine from the rounded OEM bulb to the Hanwei standard nut which you can use an Allen head wrench on and which also extends out of the keyed pommel a longer distance. This makes it quicker and easier to take apart and reassemble. I use blue locktite and screw it down firmly. I have not had it loosen over literally years of bottle cutting and solo form practice.
