Sounds as if you've nicked your blade or bent the kerf in some way.  You don't name the machine but I'm ASSUMING it's not caused by blade wobble.  The tuning steels DO NOT SHARPEN the blade. They simply dress the cutting kerf.  You lift the inner edge to keep it from curling under and you flatten the top with the other to keep the blade from "biting into your hide".  Sharpening a blade needs to be done by professionals with special equipment.  I HAVE sharpened my blades a bit by using a carborundum stone with a sharp corner.  Placing the corner into the inner radius of the blade bend will sharpen the blade, but remember, you're eating away surface. Eventually, you won't have any edge left.  Tuning the blades just keeps them straight and narrow in their operating band.

sounds like you have a nick or dent/chunk missing in your blade,  Maybe you hit a bullet/pellet or a rock,  To get rid of it you will need to have your blade reground.  Oh and overusing your steels can also cause the chatter. Go light on the steels till you learn the feel of them, its not really something you can describe.... Maybe one of the other guys can.... But I can't.

George, only you, can manage to find a word, I have never heard before! Kerf? The only thing I can think of is tip.LMAO Those 1/8 inch lips, are useless as tits on a boar hog!LOL

Steel size, could also be a problem?

Just like Shelby already said, we can try to explain tuning a knife, till we are blue in the face, but putting it into words, is almost impossible! I have tried too many times before, and always felt like, I was wasting my time, in trying.

Its kinda like Taxidermy, JBX, you will get better, with experience. If you dont have any in the freezer, buy you some deer hides, and practice, before you start working on skins that you plan to mount. Tell the company, that is grinding your blades, you want a lip, at least, half that size, and keep at it. You will get the hang of it, I promise!

Have a good one, watch those fingers, and take it slowwwww!

Actually, OS, Tits on a boar hog are kinda important! Shows good matrenal traits that are passed to offspring! But I'll let you two argue about whether or not its lips, tips, or Kerf. However, On a wood or metal cutting saw blade, Kerf is the right term.
