Just curious what rake angles other saw sharpeners use. As some of you know I am in the process of rehabbing about 4 back saws and have sharpened about 3 of them so far. Previously I just stuck with the recommendations of Vintage Saws, since I mostly had one saw to sharpen at a time. This time I had multiples so I experimented a bit. The rip was filed with a 4 deg rake which I think is just about perfect for my needs. On the X-cuts I have tried both 4 deg and 8 deg. The 4 deg was a little too steep, the saw wanted to grab all the time and the cut was not very smooth either. The 8 deg is much better, still grabs when starting but cuts very smooth and fast. Is there any significant advantage going higher than 8 deg, the most common recommended angle I have seen is around 12-15 deg range. For me that doesn't cut fast enough.
just curious what angles others use or recommend, or do you have saws with multiple configuration for various woods.
