[Steam-engine] Wachs vertical Excentric oiling question

[Richard Strobel]

Howdy again gang...real nice day here in the big sky.

  I've temporarily assembled the "D" valve operating mechanism and hung in 
on the engine hoist and put a pointer on the reservoir for the excentric and 
the pivot on the slide guide.

  Here's a closeup of the small reservoir.

  To my knowledge, there are no provisions for automatically filling this 
reservoir cup.  The upper bearing surface does show signs of being hot.

  This is a dry crankcase, and from the slide guide on down are hidden 
pretty good by the connecting rod and crosshead.

What would your suggestions be for maintaining lube in this so-called 
Reservoir??

TIA
