Were discussing a lot of lead, lately. Please be very safety conscious with lead as we are with radioactive things. Breathing and injestion as well contact through the skin.  My daughters job is working with lead wheel weights, manufacturing and distribution to shops like Wal Mart, etc. She has to come home and shower before she can touch or hug the kids, or eat or drink anything. She has to have her lead level checked during the year, a few times. It's very close to being as hazardous as radioactive stuff. Heck, I guess it once was uranium. Be safe, wear your masks and gloves. Bob
