Um-hmm, I'm thinking cold connections. It's something I've been dancing around for quite awhile now; I'm not sure I'm actually going to give it a go, but I'm thinking about it. I'm not as comfortable with my hammer as I should be; sometimes I slip. That's okay when I'm working metal; I can always file or pound a bit more to disguise my oopsies; but riveting things together, especially things that break when hit with a hammer, requires precision.
And a light touch, I fear.
I'm a bull in a china shop; I plow through and make things happen by whatever means necessary. More heat, more solder, and file off the odd spot; that's my credo.
Holding things together with single piece of wire and a few taps of a hammer scares me.
