Reworking the 273 Adjustable Rockers

If I remember, when I get back from Maine on Monday or Tuesday, I'll get dimension and pix. The grooves are definitely angled a bit from the axis of the shaft, but I'm not convinced it really matters to oiling, or was just a matter of the machining setup or something else.

Oh, and a typical chainsaw file would be too thick to cut the grooves; a Dremel, or air cutoff tool, and cutting wheel is more like it.
