The antique dealer also said that he felt the break could be repaired by making an impression from elsewhere on the carving and making a plastic piece that would fill it in.
That not only helped to protect where the two parts of the break come together,……. as there was a slight amount of movement around the threads.
I finally got around to reading this thread and figured I should add my 2 cents on the above, better late than never, for what it might be worth.
I agree, the “allthread” is a recent repair, recent meaning any time in the last 30 – 40 years. It needs to be re-repaired because of that “wiggle” because it will only continue to get worse and which is actually not a big deal to fix it.
Iffen it was me I would do the following: 1. Purchase some Epoxy at WalMart, etc. The type that comes in two (2) little “squeeze” tubes and you mix just enough of each together to make a repair. But don’t mix more than you need at any given time. 3. Get a 5” or 6” long flat blade screwdriver for mixing, etc. 4. Use a black “felt tip” magic marker to mark the “allthread” at the center line of the break in the handle. (see picture above) 5. Grasp the two parts of the handle and unscrew the smaller part. They will come apart and the “allthread” will still be in one of them but it doesn’t matter which one. 6. Get 2 hex nuts and put them on the end of the “allthread” and tighten them “tight together” using 2 wrenches. 7. Then put one wrench on the nut closest to the other part of the handle and unscrew the “allthread” from the other part …… but remember which part that was.
Now you are ready to make the re-repair. And remember it goes back together in reverse order from the way it came apart.
8. Now, squeeze out a 3/4“ round dab from each tube of epoxy, side by side, on a piece of cardboard and using the “flat blade” screwdriver, mix the two together. 9. Pick up the part of the handle that you last removed the “allthread” from and using the screwdriver, put about ½ of the mix inside of the hole in the handle and spread the rest of the mix up the threads of the “allthread” to within ½” of that black “center” mark. 10. Hold the handle so the hole is pointing upward and screw the “all thread” back into it. Put the wrench on the top nut and screw it down until the black “center” mark is back where it originally was. 11. Give it 3 or 4 hours to “cure”.
12. Take the two wrenches and remove those 2 hex nuts from the “allthread”. 13. Repeat the procedure: mix up a dab of epoxy, part in hole in handle, part on threads, screw handle down on “allthread” to where it originally was, let it cure
Or, take it to someone that has worked with that epoxy.
And that was so long I'll hafta say it was "my 50 cents worth".
