How much heat can Rhino Horn handle?

You could do it using a puk welding machine.. I have one ideal for this type of job. It is welding through 10x optics with a needle electrode. Expensive kit and a steep learning curve. An even better way is laser welding but I do not have a laser welding unit and your job might not fit in the laser unit. I live in the UK. I would find a jeweller or silversmith in your area that is using a puk welding unit near you should be straight forward. I better pic would help.

Again, thank you for taking the time to help me with this. The Jeweller I spoke to did mention a laser welding machine when i asked him about another restoration that I want help with, but he said that laser welding equipment is expensive. He did know a good jeweller in Stockholm that had one and could help me with that one. Im going down to Stockholm in the spring, so I might let him weld this one to.
I will have to have a good think about this one. That plastic steel is a good option to, but I liked the idea of soldering since it can be un-done, as you all know epoxys are not easy to remove once hardened.

Ideally I guess you would want to restore the item using historically correct methods if possible? I think I have read posts here about using traditional resins to re-attach grips etc.

You may want to check out Paraloid B-72 (http://www.conservation-resources.co...roducts_id=600) which is supposedly used by professionals at museums to restore antiques. It’s favoured as it’s less visible, degrades less, and is supposedly reversible. I have found it more difficult than expected to work with myself. I would try buying the glue tube version rather than the pellets.

Yes worth doing properly. Done well would not look any different to. silver soldering. Someone in Stockholm will have either a PUK weld or Laser unit. They will probably want a low 3 figure sum for this rather precious job.

This would definitely be a better option.

Hi
I know nothing about laser welding having never looked at it before this morning when I watched a you tube video or two
Will it not leave a bead of weld at the join of the 2 metals which will look wrong
And from my experience your eye will be drawn to the repair every time you pick up the item

The proper way would be to remove the handles and solder on the inside as it was originally made as far as I know but I might be incorrect on the manafacturing process , would this be possible

It looks to be a lovely sword and you are a brave man to do working on it

Can the cross guard be wedged in place with spacers of balsa, this will be totally reversible and as the sword is now a decorative item the repair will not detract

With this welding job you have one go at it and the people doing the job are not expert at the repair job, quiet a scary situation

Regards

Ken

Ken, this would only be done by experienced crafts people. This job would be on the micro scale even if you had to feed in silver wire to fill large gaps it would not look like the weld on an international oil fed pipe.
