Ivy: Silicon Carbide Pt. 3

Finally finished all 36 holes.  Finally.

Started truing and got it from a 6mm runout / 2mm hop down to 0.4mm/1.0mm.

Continued Dremel'ing with the silicon carbide.  Used up another 4 bits.  It takes 150-200 "rotations" inside the hole to get it wide enough.

Silicon carbide bits seemed better, but they still wear down pretty quickly.  The one I had only lasted for 5 holes before breaking.  I ordered another 20 from Amazon.
