the machine work in the chamber amazes me.  i am easily amazed, but it took at least 2 cuts on different planes to make it.  very cool to me.

next will cc this old thing to see how it ticks before further disassembly.

hope to get squish and trapped comp this evening.  got to mix up some putty.

so far beer based plan is to vinegar soak the cylinder to get rid of the rust ring.

rechecked chamber volume.  13cc. 

took everything apart, soaking in vinegar.  do not know if this will actually work for cleaning.

CN Rail was running them into the early 80's when we could no longer easily source parts, the only saw that had the torque to cut creosoted ties.
