I also did some tests silver soldering 2 similar sized dummy steel blanks together, more out of morbid curiosity since I have no prior experience with this. I could get what appeared as an acceptable looking joint that seemed to be penetrating the annular gap which needs to be quite small for gear concentricity. But I was getting enough of a fillet that I thought was going to interfere with the teeth meshing & filing it out did not seem like fun. The tester blanks came to a decent red glow by the time the flux turned glassy & silver solder melted. I don’t think the heat would adversely affect the commercial gear alloy as they were unhardened. But it also took some effort to clean the blanks after soldering, so I am going to have to figure out pickling & all that. In summary it was an interesting exercise I would like to return to one day, but I chickened out for this application.
