Drillin' for fillin'...

[nachoman]

Interesting technique. When attaching details to cast metal parts, I usually drill a small hole in each part and make a little brass wire pin to span the joint. The whole thing can then be glued with CA or epoxy, and the pin makes it tremendously stronger. Your situation is a bit different in that you needed some kind of a post to secure the plastic lever to. Just using CA to attach the lever to the metal would not have held for long, especially with the lack of surface area to attach to. I think your solution is perfect.
