Ski planing using a 1 3/4" bottom cleaning bit
Yesterday I received my 1 3/4" bottom cleaning bit from America and had to test it straight away, with rather surprising results. It took very little time to plane the surface of this very cupped piece of Jarrah, I then, having a reference surface, cleaned-up the other side because it fitted into the planer. It could well have been flipped over and planed like the first side. On close examination I could feel small ridges in the routed side which at first puzzled me. After a while it dawned on me what probably caused it, the four corners were not EXACTLY the same height, and with such a large bit it was tilted a fraction. With a smaller straight bit this would not have been at all a problem and to prove the theory I fitted the 25mm (1") bit that I normally use and re-planed the piece and it was now perfectly smooth.
My conclusion is that if one wants to precision set the four corners of the Skis, which takes time, then the large bit would be fine, but if a quick set-up is the order of the day, then a smaller bit would be the way to go and probably be the fastest of the two.
