Much chaos and delays in getting to work on this, but some progress. I have one hub finished and the other well along now. The second hub was worn so thin I had a bit of drop through to deal with and as a result I didn't get a portion of it filled sufficiently so i want to revisit it and improve it....

I've seen a number of high build videos using the ERCuAl-A2 Aluminum Bronze, including a Jody vid building an entire vise mounting ear from all buildup. Since this will be entirely in compression or even no load since it's just a pivot and can be re-clocked to put the load on the un-repaired side, I...

A project to repair badly worn areas on two cast iron hubs has landed on my bench. These hubs are pivots (partial rotation and slow) that normally ride in a nylon bushing and when those bushings wore out they didn't get replaced resulting in a large amount of wear up to about 3/8". From what I'...

More searching and it's appearing that TIG brazing with ERCuAl-A2 may be the best bet and far cheaper than nickel rod.

When I have a chance later I will try the spark / file tests to try to confirm the material. TIG is also an option if it might be better.

I have two cast iron hubs that I need to repair some serious worn areas on. The problem area is about 4" diameter and is worn up to about 3/8" deep about halfway around. These ride in nylon bushings and are a pivot point, not full rotation, and someone did not replace the worn out nylon bu...
