It all honesty it was very tough to train skills to young men on the job. It takes time. And that cuts into production. .
How true that is Jerry. No matter whether it was ultility work or logging , training on the job has a price and that's production. In my later years at the cut and skid logging camp I worked out of, it seemed like I was the only one to take a trainee under my wing. All the other guys couldn't be bothered so I guess I had the patience and the generousity to help someone out.....and my foremen wasn't allowed to work the equipment.
I only trained when my regular logging partner was sick or off for sore back reasons. But today as an arborist I still have the training bug, only thing is I don't want to do it full time......not yet anyways.
Yes the Stihl file holder works just as well as the Oregon model, the Stihl holder has a nice designed tightening nut versus Oregon's cheap wing nut. ha ha.
It's no secret how to judge when a sawchain needs to be touched up or sharpened. Just look down at the front edge of the cutter's top plate cutting edge, if you see a band of shiny light along that edge that means it's dull, if it's sharp there is nothing to see .....unless you are looking through a magnifying glass then only then can you see the sharp cutting edge contour.
My experience is after past age 45 I need reading glasses to properly "see" the cutting edge...... so you gotta do what you gotta do, to do it right.
I found fallers who swapped chains throughout the day were not good hand filers and relied on the bench grinder at home, they messed around carrying pre sharpened chains that eventually through out the day got dull from the cutters rubbing against each other.
They could have touched up a chain faster with the file then the time it takes to swap a chain loop. And not being good hand filers, when their last sharp loop slowed right down they would resort to the flat file to lower the depth gauges to get a little of the cutting speed back....put a sharp edge on that chain later....over bite and severe kickback potential.
Learn how to touch up your chain at the stump before it gets "dull"!
Another tip to save your knuckles, always file the right hand cutters first, because when you should slip your file out of the right hand cutters gullet ...you won't have a sharp left hand cutter to make contact with your index finger knuckle which would slice you to the bone, even right through a heavy leather glove.
