does anyone know of a video where it shows someone sharpening the belly of a knife on a belt sander? I'm having a hard time keeping the right angle.
It is hard to explain in writing all the little nuances of sharpening. I have spent countless hours beating around it, but I will never be able to accurately explain "All" the little nuances - and those nuances vary with different shaped blades, different lengths and different equipment.
For most people, the belly doesn't seem to be a significant problem area. <img src="/ubbthreads/images/graemlins/confused.gif" alt="" /> Tips and recurves tend to be more common problems.
I have seen some different people post their own tips on tips <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />, but those posts are probably well scattered around. I would probably search the various sharpening threads. There have been a few.
In the end, the best thing is to just practice with different shaped and sized "CHEAP" blades first. Then attempt your nicer blades. Idealy, you can practice on a cheap blade that has a similar size and shape to the one you want to work on.
Google Video has a "Few" good videos and a TON of crappy sharpening videos. I am sure without having a fair amount of your own experience most of the crappy videos cause more problems than do good.
BrianA has some pretty darn good videos at his web-site. Some of the best I know of.
