Walter would remain quiet as he had dozens of washers scattered upon a table  and he was quietly linking and patching them together with calm steady hands and precision and as he worked they formed a kind of metal mesh. Many would know of chain armor but probably fewer have ever seen how it could be made from such simplistic items as a bunch of washers and twine. Or in this case surgery twine to be exact. Walter however wasn't making a full suit but rather was focusing  on the limbs and shoulders as the parts he wanted to have protected. Hopefully those things wouldn't be able to bite through metal but if all goes well at least they might have some kind of protection from a zombie at close quarters combat. This took a tremendous amount of time and patience but in the dead silence of the majority of what went on, Walter felt it best to keep himself busy lest he might go mad from all this.
