On September 28, 2007 I started building my Master Chief Armor with the helmet.  Currently I am still working on the project.

Updates:

As of October 11, almost two weeks after I began the project, I have finished building the Helmet, Chestplate, Belt/Codpiece, and biceps.  Yesterday I bought some black underarmor at walmart to wear under the armor.  I put on the completed pieces today and... wow... it looks great so far!  I can't wait until it's all finsished.
