Mike,
I was in Pompei in 2000 and saw the lead pipes that were used to distribute water throughout the town. They even had valves to turn the water on and off, It looked like they made the pipe by rolling a sheet around a dowell and then folding the lead to make a seal. They may have used other methods also that I did not see. It was pretty interesting. We seldom give the antients credit for what they did and think of things like indoor plumbing is something new. According to the guide, they knew that Lead was a problem back then (Pompei was covered with ash from nearby Mt. Vesuvuis in 79 AD). They were in the process of changing from lead to something else which I cannot remember. 73, Harry, W3IIT "Mike Coslo" wrote in message t... kenneth scharf wrote: Jeff Spidle wrote: hmmm, I have recently had the same discussion with my XYL, we have a 1 yr old.

In my production engineering job I would routinely hold
my breath and stick my head in over the solder wave in the wave solder machine. Large amounts of soldering fumes would come up from that molten commercial-grade organic solder. After pulling my head out, I'd exhale. One time I did this maybe 20 times a day for a week in the pursuit of soldering refinements. Aggravated by poor sleep from a change in the work routine, my health went down hill quickly. My ankles were puffing up, possibly indicating the onset of liver disease. I got the message. I stopped exposing myself to the airborne lead and flux particles. It took several months for the swelling of the ankles to go away. Workers at the factory would set up muffin fans to suck the hand-soldering fumes away from them. This is a good idea. Otherwise, the fumes seek out the rising column of air around one's body and are thus breathed in directly. Also, most people lean over the work while soldering. Doing soldering next to muffin fan and a cracked down-wind window should readily resolve the problem for the most cautious hobbyist solderer and family members. Regarding someone's comment about putting solder in his mouth: Remember the historians' speculations about the contribution of lead wine vessels toward the fall of the Roman empire. Also, I can taste regular spool solder. That means I'm dissolving something from it. Henry Hello everyone, My wife and I had been 'discussing' some of the effects of my hobby, such as the possible exposure of my 2-month old baby girl to lead vapor from soldering. I typically have been using coventional 2% silver electronics solder wire with my 12 watt pencil. I do a few connections every day, but my wife wants to take absolutely no chances, and on reflection, I don't really want to either. I'd like to know if here is anyone in the homebrew community who uses lead-free solder for fine electronics work, what brands or compositions they recommend, and where such can be obtained retail for a reasonable cost. Oh, yes, and can someone lend me a yard of it until I can afford my own large spool? Thanks in advance, The Eternal Squire --- Outgoing mail is certified Virus Free.

Henry, your ventilation on the wave solder machine is all wrong! If you need to look into it, therre is no way that the vent air pull should be past your face. That thing should have a side plenum vent. the fouled air will then not make it to you when you look in it. As has been stated, the fumes are from the flux, and I have inhaled a bunch of it:-). The lead portion can only hurt you if it is ingested, not sniffed. I am sorry you had health problems, but it may not be for the reason you If rosin based fumes are bad for you, than I get a double whammy, since I make telescopes too, and the polishing laps are made out of pine pitch. Between that and the soldering rosin, my garage always smells like pine. Yummy! - Mike - |

Hi Henry, that was not the best idea in the world, but I have been soldering for over 40 years, and have never experienced any health symptoms like you describe. I solder a lot, both at work and at home as a ham. I'm 57 and never had health problems. I think you should look for other sources for your apparent health problems. Henry, your ventilation on the wave solder machine is all wrong! If you need to look into it, therre is no way that the vent air pull should be past your face. That thing should have a side plenum vent. the fouled air will then not make it to you when you look in it. As has been stated, the fumes are from the flux, and I have inhaled a bunch of it:-). The lead portion can only hurt you if it is ingested, not sniffed. I am sorry you had health problems, but it may not be for the reason you If rosin based fumes are bad for you, than I get a double whammy, since I make telescopes too, and the polishing laps are made out of pine pitch. Between that and the soldering rosin, my garage always smells like pine. Yummy! - Mike - |
