Jim, do you find that the speed of the saw and the speed of the cut also tends to influence the width of the kerf? When I do my sample cut on a piece of scrap, if I use a higher speeds, I seem to get a wider kerf which influences the fit. In a perfect world, I would love to have the inlay a tiny bit smaller so that it needs to be lightly tapped into place. Even when using scrap pieces cut from the working stock, I am experiencing variability that is puzzling. It seems that the speed of the blade and the speed of the cut will influence the width of the kerf. I would be interested to get your perspective on this.
