Let’s try to keep this discussion to the topic of sizing rings in particular, even more specifically, gold and silver alloys (my apologies, Mr. Grahl, but we know platinum is special).
For the last 15 years of my bench career, I have sized rings with solder. Usually a plumb solder to match the alloy being sized. However, people on this forum have occasionally mentioned fusing (using the same alloy) to make the joint. This usually leads to hours of nervous fretting while I question all I’ve been taught. In these moments of self-doubt, I have attempted to fuse and have had limited success. Then I revert back to my soldering ways until the next time someone triggers me. So I want to know what are the accepted guidelines for when to solder and when to fuse. Do some alloys work better for this than others? Is this simply personal preference or has experience led you to chose one method over the other?
Let the games begin!
