Ron, I wasn't suggesting scrub planes as a step in a process in planing a timber flat & smooth, as I see only two steps in that process, the first involving a cord. (All timber here is purchased locally and rough sawn, and planed with a 12" power plane with out much attention paid to dimension or squaredness - That's but two passes on each face following a bandmill - And even planing up & out on Rough or textured frames for ease of snapping, drawing, and scoring lines)

But suggesting scrub plane ripples as a finish unto itself, sort of an easily achieved subdued hewing some find appealing.
