You have to burn the lead out with a blow torch make sure you have a fire extinguisher handy.If the joint is easy to get at you can sometimes drill out the lead but you normally end up burning it out anyway.Make sure the area is well ventilated and be carefull when you pull the yarn out the joint it bursts into flame as it hits the air. Hope this helps, Calked lead joints who needs them.
