Arnold - that's a beaut of a runner you've got there! I was worried that she might fly off the track at the first corner, she was up to such a good clip, and sounds spot-on. She's really living up to the name "Cracker"
A quick side-note about solder:
- Olde Worlde electronics & plumbing solder were 60% tin, 40% lead, or very close to. This mixture melts readily, and re-melts readily too. You can still buy it (in the UK at least), e.g from Farnell.
- New electronics (and maybe plumbing?) solder is a mixture of tin & copper - 99.3% tin, 0.7% copper according to the reel I have here. I believe some lead-free solders also contain silver. Lead-free generally melts at a higher temperature than the old lead/tin mix, and needs different fluxes.
The old stuff (& rosin flux, which is also pretty much considered to be evil these days) smells much better than the new stuff, and is easier to use IMHO.
