Yes, they are inertia driven.
Kickback that doesn't engage the brake means either the inertia wasn't high enough to trip the brake, which means it wasn't high enough to cause you injury. OR it was high enough to cause you injury, and you allowed your chain brake to become faulty by not following the testing procedures in your manual.
That statement couldn't be further from the truth.
My statement was 'generally speaking'. Of course there are exceptions to the rule, however, I have found my statement to be generally true.
Well just inside the last 30 yrs there were saws on the market that I used as new in '89 professionally such as the Husquvarna 2101 (manufacturer's production yrs: '87-'90).
They have brakes but you never would have what I call an 'inertia brake kickback'
I had some scary kickbacks comming for between the eyes that bent me so far back that I hurt my lower vertebrates. Definitely much to be said about working from the side ..as one would learn.
Anyway... I am firstly addressing your first statement of you saying that chain brakes are inertia driven?
I have always separated the early from the modern (example: production yr1996, 371XP as modern)
In the past I have separated the difference in threads between the very early and what we know today as the modern inertia chain brake. This includes saws that SHOULD activate from a 1ft drop on to it's belly and/or releasing the front grip from a standing position as the tip drops onto a solid. Then of course ' The kickback Zone' I see them as automatic & manual vs manual??
After a short stint as a creek cleaner and then onto the dry sort Buckerman on the west of coast of Vancouver Island, B.C. , I then moved into tree thinning with snag falling and deciduous control so my experience with the saws with the older brakes are both limited and very dated.
I will invite anyone with a greater mechanical understanding (or otherwise) of these early chain brakes to weigh in on this what seems to be a 'fuzzy area'.
What about the 266xp
as well the 262? Was there a difference as they were about 8yrs apart? Those were the saws I ran up to the 371xp in 1996
I just don't remember the inertia kicks that are so common with the 371/372.
Maybe I am trying to block out the fact that I was a juvenile tree spacer? I do sadly remember a 21 yrs old got killed with a company I worked for in '93. That was in Chillawack with a 266. We used 16" bars because of the steep topo. He got a kickback in the neck and had no brake on the saw.
That was also the end of Rob's company which was one of the biggest spacing company's on the coast.
This is the difference I am sure I remember...
That is, you could run these early model's without a chain brake handle and there was no inner way for it to lock up??
I know the Coast Fallers were taking them off in the 80's because they would knock them on when they had to backbar big wood. This is certainly something I could see one speaking generally about or not positivity knowing the difference.
Post is long enough just to hopefully shed more light about your first statement.
*Prehaps you could explain what you ment in greator detail in the second statement that I initially quoted in your first post?
As it stands, 'it still doesn't merit my time' so I feel the onus is on you.
Brother you certainly don't want the layman's terms of my real opinion of your statement, you really don't.
I am true about learning regardless of how one may have conducted themselves. At the end of the day it was another trick in the bag and the b.s. stays on the hill. A Faller told me that he had an old guy that would hit him in the back of the head from behind with a stick ever time he did something wrong.
If you don't take your bumps then you are going away empty handed and filed under rookieville
Are you ready for a serving ?
