Re: Lead-free solder
I say, screw lead free solder!
If one does not have a temp controlled iron, the effort is a waste.
It has a higher melting point with less working time... It is more likely to spatter when un-soldered...And it needs specialized fluxes to perform the same job.
It does not flow into heated joints like lead solder, and is less likely to be satisfactory.
No one is going to die if you use good solder methods, using good solder tools. Lead is not the bogeyman, as long as normal modern methods are used.

On the larger Earth scale, far more lead is introduced into the eco-system through the common "sweated joints" of copper plumbing during house construction...or in the auto industry, where car batteries full of lead/acid are recycled...as well as crashed on city streets.
A small "pancake" fan, as those used to cool computer power supplies, are good for clearing fumes. The fumes burnt off regular flux compounds don't bother me at my job, but that is not to say some people cannot be really sensitive to even small amounts of the cook-off.
