Re: Ripping chain cut narrow when cutting across the log?

Would it be normal for ripping chain to cut narrow when cutting across a log?  The chain I used to cut lumber with got used a couple times to cut fire wood and seems to cut narrow and stick the blade.
Yes most definately it will cut narrower because of the ripping chain's 0 - 10 degree top plate angle. The opposing cutters attached to the sawchain's chassis have some play in the rivet hub / drive link area, so a sharper 30-35 degree top plate angle will allow the cutters pull outwards and cut a wider kerf.

An old trick I do when my chisel cutters are filed down to the witness marks and the chain doesn't cut so good especially if the bar rails are spread more then normal which causes the chain to cut on and off in the wood. What I do is file a much bigger angle like 45 degrees then the witness mark's standard 30 degree , gives me some extra filing life and the chain cuts good again.
When the cutters are filed back this small safety with the more aggressive angle is not an issue, only edge holding capability is lost a little.
