    You could consider using German silver, or pewter wire. Screw a bolt into the threads, then fill the hacksaw slits with the GS, or pewter rods and carefully hammer the rods to smush out and fill the void. Both metals are soft, and should be close to the nickel color. You can find German silver wire on ebay in many gauges, and quite inexpensive. I've never done this; just throwing it out there

    Eric!

    Pewter would certainly be too soft.
    Carl O. turned me on to some silver-solder that is pretty miraculous.

    Just got to work up the nerve...

    This is what I've used. Got it at a local welding supply house. Expensive, but you shouldn't need much. It's flux coated, and it's liquid at 1370 F. This is 45% silver, you can get it with higher silver content and a lower melting point, for more money. I would probably consider inserting a thin piece of brass in the gap, and silver brazing it in because I've been told that brazing is strongest in a thin gap, about .0015 inch. Just a thought. Whatever you do, I hope it works out for you.

    I do a lot of silver soldering (just yesterday) and it takes a lot of heat to the parent metal to melt, and properly accept silver solder, which could discolor the nickel plating. That is why I mentioned forming a filler metal into the hacksaw slits, instead of soldering. Perhaps a low melting point jewler's silver solder would have less of a risk of discoloration.

    I appreciate the replies, Folks,...

    But I gotta do what I gotta do (attached).

    Now... What do I charge for this rescue?

    Beautiful repair, Tom; absolutely first class. I never know what to charge people, so I would double whatever I would charge

    That is a great looking repair. What did you use in the end and what was the flow temp.? Did you do anything to protect the nickel?

    Sorry Jim,..

    But every time I let out a secret, some barnyard outfit starts offering it on some other forum.

    The color suggests a soft silver solder.
