   I'm not 100% sure of the cross section you're trying to achieve, but the standard answer for making a straight cut on a log is to mount it on a plywood sled with a runner sized to your miter slot. Alternately you can mount a plywood box jig to the log and use a router.

   If I understand you correctly , you want to rabbet one side of a log on a 45° angle.Fasten a straight edge for a router with a 45° champher bit,remove the bearing if there is one.The straight edge can be two pieces.Thin piece for the router to sit on and another attached to the thin base for the straight guide. This way the router will slide easier than if you slid over the log itself.The rabbet may not be the same width and depth if the log face is not flat.

   If you want you could plane a narrow surface flat before routing the champher.

   I like the plywood box idea- I hadn't really considered using a router like that. I'm not sure I can find the base plate for my router though- since I've had it mounted in a table and moved a couple times- who knows where it could be...
   I'll go stare at the log pieces for another hour and see what else I might be able to think up.
