So I've been around a few older saws and a few newer saws, all of the being direct drive, and my general observation is that the newer ones have greater cutting speed, and the older ones have more torque. I can understand how gear drive would greatly increase torque, but what is it about the older direct drives that give them more torque than the newer saws (all direct drive as far as I know)? Heavier cranks?
And why can't the older saws be tuned to run regularly at the new saws rpms? Tolerances?
Thanks in advance for any replies!
