My neighboring sawmill and mine had a Logger That Ran a chain so loose there would be AT LEAST 1" of daylight on a 28" bar. Larry would start with a snug chain but seldom stopped to retension it (LAZEE) and some times the stretched chain needed shortened. He cut Cottonwood and other pallet logs for me and walnut and grade logs for the neighbor. He got started logging when ground for the Milford Kansas Damn was being cleared. A lot of lumber had to be left. He started with a hard nose bar in the 50s' .. When cutting walnut there is a lot of Bore cutting and he still had a loose chain, not many twigs (branches) but a sh#t load of buck brush to clear before the cut. Before he laid the saw sideways the chain was moving . My neighbor (and Me) still mention this every once in a while. He would use J 2095/5 or 2188 or Stihl 051, 56, 084 when I would see him logging Sometimes he used a 48" bar same slack. He seldom threw a chain. Side not he was 5ft. 6or so inches and less than 140 lbs. He logged here locally from 1969 or 1970 to 2002?(guessing from memory) My long winded comment is attempting to acknowledge "TECHNIQUE" and "EXPERIENCE" Has a place when using a chainsaw and you may not realize it but you are certainly acquiring it and yes I have read every post on this thread so far and I am still gleaning information. Thanks for starting it.
