Operation 60: Cold Bluing Operation

Cold bluing will be used to create a more rust preventative surface coating on the Cylindrical Washers after they are completely machined and deburred.

Watch the video to the left, pay attention to the cold bluing section of the video. We will use the same Birchwood Casey cold bluing chemical to blue the Cylindrical Washers.

Note: This is the same process used on project 1 to cold blue the step block bases.
