Maybe this comment was missed? It would seem to indicate that a longer than normal bar would be used for the odd cut where the bar length is desired.
Power head wear has never been questioned and overall cost comparisons of buying a larger power head vs wear factor costs for a few cuts should be considered.
Chain speed is a variable. It should remain constant at a set point determined by tuning as long as the maximum power requirement of the engine is not exceeded.
The power requirement demanded by the chain has many variables. These can be adjusted to kept the power demand within the power band of the power head. Being older I could even refer to Slugs in reference to the power demand.
So why should I be taking medications Waynebro? Are you qualified to evaluate and dispense medications or are you working on a "Sir Yes Sir" type type format? Cause if you are it will not work. Saluting has never been an ambition in my life.
I also believe the Canadian school system is working quite well. It should be right on Parr with other G8 nations.
