Title: Blade Carnage
Post by: fluidpowerpro on July 25, 2024, 02:51:35 PM
Been sawing at home the last few days and hit a nail in one of my logs.
Here is what a 10 penny ring shank nail will do to a blade. I've never seen a nail do so much damage to a blade. Maybe its because ring shanks are, I think extra hard. It certainly was a pain to dig out of the log. 
No doubt many of you have seen much worse however this so far is mine. 
This must be the summer of nails because I have never hit so many in such a short period of time. Maybe its because I'm using new blades that I have not sharpened myself yet.

Thinking it would be a good thread to keep going with more posts of Blade Carnage.

Wow, that's painful to see.  I don't think I've ever had a regular nail do that to a blade.  Bigger stuff has but not a nail.  Sorry it has to happen to a new blade- that hurts all the way around.

It must've been a pole barn nail. They are ring shank and hardened. Hardened steel will take care of a blade, for sure.

Just wait until ya hit the hard stuff. Drill bits, increment borer (unlucky forester), and the undisputed king is the porcelain insulator. All three will take all the teeth but with a insulator strike you can't even tell the blade ever had teeth. ffcheesy ffcheesy

Of course it was a new blade: metal seems to come near the surface once you replace a blade...  :wink_2:

I was sawing Black Locust one day and heard the hit, didn't know what it was but the scream from the band was like a Yeti death yell.  So I grab my chain saw to cut off the slab so I can figure out what to do - yup the saw began to scream just a bad - hit a porcelain fence insulator both times....There was nothing left to the band or the chain.

If a day starts like that, I just go back in the house.

Been there done that more than once. :veryangry:  I'm in an old mining area, where every tree was considered a potential power pole.

No pictures. but one time we were sawing up some cedar logs, with my old Stihl powered swing blade. I noticed the mill wasn't cutting as well as it should. Shut down to check, and the old blade (no idea how old, it came with the used mill), and ONE carbide left (from 6). It actually still cut, just not very well.  ffcheesy

I've hit about everything you can imagine. Insulator and cotton picker spindles are the worst for me. The only thing that lined up in the same class was when I hit a 12" long flat b@#$%d file that some farmer had laid in the fork of a tree, years earlier.

Ian,

  During a service loop stop over a couple years back the WM service team found a similar case to what you describe only it was on my debarker blade. It was down to one tooth and I had not noticed.

A file: that's handy, steel doesn't get a whole lot harder than that...

The frame of the pulley didn't cause the blade much grief. . . then it hit the hardened pin that the pulley wheel spins on. 
Full Stop.

Wrecked this one twice and put into spider web storage. Insulators

"Someome" hit my log turner with the Debarker which will shell the teeth off of the blade, so I've been told by a friend.  smiley_smug01

 Being that you don't let anyone else handle Mrs. Pat or your sawmill controls, I think I know who "someone" is😊
