A Ta tube was coated with TaC.  The inner of the tube was filled with TaC solution and the excess was drained out to give a homogenous coating.
 The outer layer of the tube was brushed with TaC.

The endcaps are stacked together with a punched out disc of graphite foil placed in between each endcap for separation so endcaps won't fuse together.
The end caps are further wrapped in a larger piece of graphite foil to hold together as a tube [same method used in elogID # 158]
