Last November, while I was at Woodworking In America, I participated in a class on Western saw design. When preparing for the class I tried writing notes on how saw teeth work and I got totally bogged down. Everything is intermingled. Aside from explaining the terms used in saw tooth design you have this whole question on why we make a saw finer or coarser, the effect of changing the angle of the teeth, and all the other factors that influence how a saw cuts. So at the end of the day we came up with a chart that shows how it all works and we think this makes the terminology a little more comprehensible.
Download the chart here. I hope you find it useful.
