I forgot to add this to the first post. I talked to Jack Sobon once about hand planing, and he makes two passes. The first cleans up most of the band marks and any dirt, and the second is made with a freshly sharpened iron to leave a nice, smooth, although still undulating, finish.

In white pine, I think I could hand plane band sawn timbers in one pass at a rate of two square feet per minute. I haven't tried the two pass technique yet.
