MIG and TIG welding, plasma cutting, milling, lathe, laser etching, embroidery, commecial-grade sewing, and more can all be done at TechShop in Menlo Park -- http://www.techshop.ws. They have one hour classes on all the above machines (and more). The woodworking community workshop is The Sawdust Shop in Sunnyvale -- http://www.sawdustshop.com/. I've never been there but hear that it's fun. The tape stuff is Rescue Tape -- http://www.rescueta pe.com/. It's awesome stuff. I got mine at the bike show last year for a much better price than is on their website; I think it's probably worth waiting until the show to see if they have a booth again this year.
