Excellent suggestion, shortbus. I've already bought 3 syringes and they're on their way. Many thanks!I just don't think if your going to depend on those micro welds to hold your pin in place that it will work, be strong enough. Those welders are mainly for jewelry not for something mechanical. For strength in a 90 degree joint situation like your doing, you need a fillet of some sort. And to get a fillet you need to add material to the joint.
I forgot all about this stuff before, but thought of it overnight. https://www.riogrande.com/Product/SilverPasteSolderSyringe560ExtraEasy/103101 Using it you would apply to the joint and fixture the parts in position and heat. It's a well respected way of doing jewelry work.
