I'm only on my second model but hope to get to more complex units as my skill level allows.
As I look at multi cylinder models I wonder how lubrication is catered for.
Many have exposed crankshafts, particularly I/C engines, so a sump wouldn't work.
Some thoughts would be appreciated...
I am building an opposed piston engine which I downloaded. It has its origins in the December 1977 issue of Popular Science.
On the drawings it has a number of letters inside a small circle. These paper adjacent to dimensions. they are (separately) a C, an S, and a P.
Can anyone enlighten...
