Some tools just have a mind of their own. I'm trying to figure out how a 12" by 6" piece of quality walnut came out of the planer lower on one corner than the other. The wood looked fine when the whole board was jointed. I'm bummed because this particular piece was supposed to be a show face on the clock it was destined for.
Back to the planer problem. My theory is that my feeding pieces to alternating sides of the 12" planer somehow skewed/elevated the board while the corner was between feed rollers. There is an analog in the computing field where I have some real expertise: I often want the computer to do what I want, not what I told it to do. I guess the machinery in any field is a harsh reflection of the operator's skill.
On the bright side, some small taper files arrived today. I'm taking up saw sharpening, but was stymied by the dearth of taper file options in the retail world. I finally found what I needed at Lie-Nielsen Toolworks.
