Hey All,

So iv been sharpening on a belt sander for about a year. And yesterday as I was sharpening my fuel ignite I noticed something that puzzled me.

My edge, seems to be "polished more" in some areas than others. Every milimeter or so it alternates between polsihed to less polished.

My question is, is this due to my belts being old? Have they developed too much slack and are now "shaking" too much (thus making contact diffrently at each part of the blade)?

Thanks
Nader
 
Im havin the same issue. Having a platten helps a little but i was wondering if it would shrink a little and take out the slack i soaked the leather belt in water.
 
Its driving me nuts! Whats even wierder is that its only on one side of the blade..I should go try and expirement with different tensions. Maybe that would fix it?
 
Why is the belt going slack? What type of belt sander? Have you reached the end of the belt tension? If the polish is inconsistent are you moving the blade too fast? I usually go light pressure to remove the burr and go several slow passes per side.

Leather belt, it just naturally stretches with use (like leather wallets, shoes etc). Yeah, end of belt tension, no where else to go! Seems nice and even the blade movement, this is just a recent problem that iv developed. Iv been able to put full even shines on about 100 blades?
 
If it was really the belt would it only effect one side? I'm guessing not.

Thats a good point, but I think it could still happen. If my tension was "uneven" to being with and iv been using the machine for a year, then it could have stretched one side of the belt more than the other?
 
Wouldn't be my first or third guess. Belts are pretty cheap just get a new one and find out if that fixes the problem. I'm still guessing not. And didn't you say it was only effecting one side of the knife and not the other side? That doesn't sound like a belt problem at all to me.
