Rive first, true the dowel later; use a trivial cylindrical hydraulic cavitation method, extract dowels...only what trivial method was that again? Packing group twice, cavitate once mon.

I suppose you take off your ring and stick it on one side of the branch, push it with a series of hardwood staves while a friend brakes the stock so that a density minimum always appears true, ahead of the ring, and then continue until the limit theorem packing fails to brake?
