Stumper
One Man Band
Okay Tzed, I concede that you are technically correct but I am using common parlance. In that usage torquey saws have the ability to keep the chain moving under heavy load/in big cuts where a fast revving and cutting saw might bog down and stop cutting altogether. A screamer may fly through 10 inch wood much faster than a slower design but be difficult to use on a 30"stump cut where the slower saw keeps on cutting about as fast as it does in 10" stuff. Those of us who have run a lot of saws have observed this first hand. Personally, I haven't really compared saws of the precise same displacement just noted that some relatively slow designs don't seem relatively slow when the bars are buried. I'm trying to understand enough to know what to expect from a given saw without actually doing side by side tests.
As far as flyheel weight is concerned-compare the seemingly unstoppable ability of an old one lung diesel with a 200lb flywheel turning at 500 rpm compared to some little engine that supposedly produces the same horsepower at 3000rpm. The difference is dramatic. Smaller faster spinning engines are definitely more effecient but they bog out a LOT easier. Compare Chippers with identical engines but different size/weights of cutter wheels. Big flywheels make performance differences-responses are slower both in getting up to speed and coming back down.
Thanks everyone-keep it coming! If I'm full of beans okay-just make me understand.
