Have personally NEVER seen any bar break like that through normal use- and I have used some pretty crappy budget bars over the years.
Cannot think of ever seeing one clean break like that, but have seen plenty cracked and or bent at some pretty peculiar angles at about that point- always caused by the "nut behind the but" or a tree doing something the faller was not expecting when the log leaves the stump.
NoAnyone else had this happen?
Been used as a lever one too many times, extreme cold along with stress can shorten the life of high tensile steel.This is the second 32"sugi bar i have had that's done this. First was broken off right by the spikes. Anyone else had this happen?.View attachment 865529View attachment 865530
You'd think it would atleast bend a bit not just bust clean off. You run any Sugi's Bob? We get them pretty cheap down here it seems
I thought it could be me leaning on it or something but id expect some funky cuts . I put it in the vise to sharpen? surely it aint that. Its not a falling saw only gets used on the deck. Its spring here dont reckon its the cold its warm as. Think if it was operator error i would be breaking or bending every bar i put on. Hard to see anything by eye on break now, but when fresh you could see shiny bit just under groove about 10mm bit where it had be hanging on. I will put another bar on and see what happens.
Thanks
I’ve only used Oregon and Stihl bars, and neither commercially, but I know Oregon bars are pretty flexible. I had around 150 pounds slide down a 36 inch power match bar and, despite the tip flexing out about 3 inches out of line, it sprang back as straight and true as an arrow.And neither of those bars was ever clamped in an Alaskan style mill?
I should have worded that better- not so much jammed and clamped like those ATV mounts that clamp the bar to the vehicle, but the powerhead is unsupported, drive up and down a gravel road to a logging job a few times and the powerhead has been flexing back and forth while the bar has been held rigid- snap goes the bar eventually.
The only way I can see that happening is from repeated sideways flexion- where it is happening, I cannot tell you. Maybe get another sawyer to watch you cutting and see if he can pick it up- I have seen guys "assist" butts off of logs with a flick of the bar and not even know they were doing it.
Tempering and composition will vary between bar makers- maybe Sugi Hara are just not suited to your style and other makes are more forgiving of flex.
