OK, I tested three different chain styles on the log posted in the thread here.
First one was the Stihl Square ground chain I turned into Granberg. Only thing I have to say about that one is make sure your clearing cutters rakers are close to .020. This chain came out of the box at .035, and it was grabby as hell. Chattered all the way through the log. I could only take two cuts, and Id had enough. I would suggest using a chain thats as close to .020 to begin with, as it seems to make a world of difference.
Second was a ripping chain from Baileys. Modified to Granberg style with the scoring rakers taken down to .035. I didn't touch the clearing cutter rakers, and don't know what they are set at. This chain has been sharpened a few times prior to its transformation. It did cut faster, quite a bit, but at the cost of smoothness on the boards. It left a very rough surface.
Third was a Lazer ripping chain. Untouched. It cut just as fast as the previous chain, but left the surface very smooth. Normal for what its done in the past.
MY conclusion.....Its not worth the time and effort to cut the tops off. At least for a 28" chain its not.
