Hello all,

yesterday I started a overhaul on a boiler feed pump. inside I found special "honeycomb wear rings". these are a non standard type of wear rings. I wonder how they are made. Maybe you guys could help me. I don't have to make them, I'm just fascinated by the way they would be made. any ideas??

:D

Seriously, I wasn't around the time the boiler feed pump was torn down at work.

Some posting more pix, and maybe a manuf's website would go far.
