Yep-yep on the lead solder, but I guess it doesn't apply here. Copper and brass are really clean metals (which is why copper is so popular for pipes and pans, anyway). Anyone reading these comments can rest assured.Interesting thought on the chemistry/metallurgy vein, boatmaker. Hmmm...
Down Draft Sanding Table (On the Cheap!)*
Ooo! You could install a tube and collect the H2 gas in a balloon for fuel! KIDDING! Oh please nobody try that!This is very cool and handy... I may have to try building a backpack version if I can find a more suitable (lighter) case of similar dimensions. Ideas?

Another "yes" vote on the safety of copper heating: I have a long history of remodeling and I have done copper pipe "sweating" on both plumbing and HVAC systems in some of the strictest code states (Maryland, Florida, California etc.) and I've never run into any special hazard rules. That said, however, it might not be a bad idea to pre-heat your grill once to burn off any coatings or oils that may be there from manufacturing or handling before getting food near it. Just to be sure.
