This week the maker skills crew talks about welding. PJ makes a huge precision tool hall by outlasting everyone else at a long auction. Tom reminds us that you can get started welding with some coal and a hammer, and Tanda survived a childhood of unsupervised welding just to be on this show. If you've been wanting to learn how to weld, and you've read this far, you should go for it! (despite the lack of any practical welding advice in this episode)
