Hi everyone, Hope I have asked this question in a correct place. I have a skiving machine. Recently I have bought a new presser foot which is longer in length (5cm). After installing it on the machine, I found that the bottom curve of the presser foot does not have the same shape or curve as my bell knife nor my feeder stone. It seems that it is a bit narrower, which means there is still a thin gap in the middle after both ends of the presser foot touched the feeder stone. I hope i have explained it clearly. May I know how to solve this problem? This problem has caused the thickness of the leather skived not in consistence. Thanks in advance. Ellis

Many thanks Ferg! The article is useful. I tried to sharpen the knife very slowly and bit by bit, and the lines are fading away now! Thanks again Ferg. Ellis

Thanks Ferg, I tried and this time I stoned it longer and tried to remove the burrs that may cause, but still i can see them though they appears to be not that obvious this time. So does it mean I need to sharpen the knife in a more aggressive way: deeper and longer? And I also found that the leather tends to move upwards when feeding along. I tried to think of the logic: is it because the roller stone is more closer to the knife at the bottom side that near the user? or the "presser foot" not parallel to the roller stone? Is this thinking correct? Ellis

The leather has lines remained as the attached picture after skived by my skiving machine recently. Is it because of the problem related to the bell knife? Can it be fixed? Many thanks!
