A dozen years ago, I bought a roll of chain. I think I got it from Oregon maybe (??) They cut it into loops for me so a box arrives and I've got 20/30 individual chain loops in boxes ready to go.
(I did this because I had taken a chain out to be sharpened.... was felling a tree and the tree settled, pinching my bar. I smiled, went to garage and got my extra bar and freshly sharpened chain......which would not cut butter. They didn't touch the rakers. I'll leave it at that rather than describe how I felt, especially with a tree halfway sawn thorugh)
Now I sharpen myself. Rakers annoy me so last time I thought I'd try an experiment. I might get skinned alive for saying this but, I took my hand held 4" grinder and with a couple light touches, ground them down as best I could to zero.
Went to go cut paying attention to what's going on.... if chain got wonky I was going to flush the project and just slap another chain on. Worked great. I might do that to the rest of them when they are up for sharpening. Didn't take too long.
