To all the new members who ask questions as their first post.......STOP IT!!!!
Make an intro and tell us a bit about yourself including where you are from.
Before asking questions on topics that have been covered ad nauseum try using the search box with keywords like " burnt wire" or " stripping wire" or "tin coated wire" or what ever it is you are looking for an answer to.
There are thousands of posts here on SMF and trust me when I say ALL your questions have been anserwed at some time or another. If after searching then ask your question and someone will weigh in or direct you where to look.
