[Steam-engine] lubricating oil

Tue Apr 25 19:22:46 PDT 2006

I have a Skinner engine that I will be setting up to run a saw mill. It is  
similar to a Troy in that it is not lubricated by greasers or drip oilers. It  
has a gravity oiling system. The oil is below the engine in a reservoir it is  
pumped up into an oil water separator and then it gravity feeds the over flow 
to  the crosshead and the main crank bearings. The rod is splash lubricated 
as far  as I can see. At the bottom of the case water is separated and then oil 
runs  back into the reservoir.

  OK here is the question. Does anyone know what type of oil to use in  this 
application? Conventional oils emulsify or mix with water and make this  
creamy buttery mixture.

I was thinking of a mineral based cutting oil like what is used in a valve  
grinding machine.

Any comments or suggestions?
