Mike, you SDSOG! lol. Don't worry about that. There isn't going to be anything much faster than a fairly short toothed square ground chain on that maple and beech. A little can be gained by streamlining for chip flow at the rear of the tooth, but like Andy says, a heck of a lot more of it is up to the operator, the saw builder and having the carb set right for you and the chain. EHP can take the saw out of my hands and cut 10 to 15 percent faster almost every time. What I have learned is that it takes a heck of a lot time to get to be a consistant winner with chain and technique. You got to give the devil his dues on that.
Al, the brazed junctions are N / S poles charged by the rare earth magnets. The top of the strip is ground parallel with the base before the locating pins are set. The teeth snap on quite determined to stay put. You got to be a bit crazy to go to the trouble to disassemble and rerivet a chain to do this. It narrows the kerf 30 or 40 thou and is enough faster to win you zip if you are not doing all of the other hundred things right. It is nothing but a disease!
