Don't melt the chain!

Here's how the Polar Bear was set up today to add the third jump ring on the back. The coin is there to stop the heat melting the chains, but that plus the two sets of tweezers really absorb the heat, which means it takes quite a while for it to get to temperature for the solder to flow. Ideally all three jumps could have been soldered without the chain in place, but this piece really needed to be hanging on its chain to work out exactly where the last ring should go. Phew!
