anodizing aluminum

Today we will begin anodizing and dying aluminum and then hopefully get to an introduction of using a manual lathe. I have included handouts on both topics in the content section of D2L for you to download and print out for the demonstrations. Remember I have additional info on anodizing in the content section on resists, etc for anodizing. There may be some addition information that you find interesting. It would be beneficial to add this information to your notebook. I have included information on the anodic coating of different alloys, details on the alloys themselves and the handout on anodizing and dying that I will go over in class. 
Additional references for your interest are as follows: (LaPlantz book is number 4 and it's a great book)
