Three things I'd try:
Bore a hole in a wood scrap, put the stick in and wedge it, and fill with paraffin wax. Then,
with a heavy workbench vise, you can hold it still for a swipe or two with a sharp plane.
Low-angle (block) plane would be suitable, maybe a final pass or three with a card scraper.
Hole, wedge, wax again, only this time make a crosscut pass with a steel plywood blade in
a table saw.
Hole, wedge, wax again, only this time make a light pass with a straight carbide router bit.

Planing a loose knot is a close approximation to the task you have ahead of
you; making it a NOT-loose knot would be a high priority.

This sounds like instructions for planing the end of his "stick", like the end grain of a dowel. Am I thinking correctly?

I think he wants to plane along the length of the stick, which is a core sample, which the end grain is along its length, is perpendicular to the length.

That's correct. Wit3rd, are you thinking of encasing the core in wax and then shaving off small sections with a planner?
