Read the manuals FIRST [link] (paper copies in the cabinet, digital copies on the Group Wiki and the research drive). They are short and informative.

However the information about changing the filament (in the e-Gun Manual) is a little confusing, and we ended up successfully completing this task using our own method. This guide will explain the steps for how we changed the filament.

You'll need several small Allen keys, some flathead screwdrivers, 0.01“ and 0.04” feeler gauges |

	Here's what you see when looking at the e-gun and crucible holder from the front. The filament is around the back (you'll need to remove both sheet metal walls from the chamber to reach it).
	Here's behind the crucible holders. The filament is the curly piece of metal. To change the filament, we'll need to remove the filament, the two ceramic blocks holding the filament legs, and the cathode shield together as a unit. Before we do this, we'll need to disconnect the voltage leads from the filament. Before unscrewing anything, UNPLUG the e-Gun control unit!
