Bar Straightening and Repair

WTF? Wow. That's one for a conversation piece. LOL

 

[fearofpavement]

that one would be a challenge. I'd probably salvage the tip and put the rest onto the scrap pile.

Here's another conversation piece. Nobody knows how this happened, but it did.

This 30" Stihl bar was rather new at the time and in good shape. An experienced logger was cutting a felled cottonwood tree into 9' logs for a sawmill when the bar broke apart at the tail. He had never seen this happen in 25 years as a sawyer.

Wow. Scarry. WTF

 

[Duce]

Think those bars are used to make dug out canoes.

 

[Wood Doctor]

Wow. Scary. WTF

Yes indeed. He was using an MS 660 at the time and simply buck cutting the big logs. He normally brings in about a grand worth of logs on his flat bed to the sawmill for pallet making. He uses a 30" bar for the smaller trees and a 36" bar for the bigger ones.

That....is impressive

Sawhawgz, ruining the internet since 2012...

A good welder would put it back together. A good machinist would just make a shorter bar out of it!

The logger who did this is a good welder, but somehow he lost the small tail piece that broke off. He also doesn't do very good machining. I think he figured the $100 bar wasn't a great loss and his time was worth more as a saw operator, log loader, hauler, etc. With two men working, they can easily bring in a grand a day.

 

[Philbert]

Most guys would replace it, without s thought. A few guys would see 'a challenge '

My hardhead self would try to fix it.
I would get another bar but still spend a lot of time tryin to fix the bent one.

I don't need to think about bent bars, all mine are straight and i now have a new 28" LW Total.
Bad juju

This looks like the runoff from that bent bar thread over at AS.
Is there anyone over 40 here?
Forget the press
Hammer it, I've brought the flat memory back to a bent bar right from the nose joint right back to the tail, for over 40 years lol.
Here's a pic... anvil, hammer and a shim. I like using a bar cleaner tool which is .050 for a shim , another for .058. Just stick inside the rails and pull it along by the exposed hook as you hammer.
Hammer the bend out from both sides and opposite sides of the rails. Keep eye balling down the bar until it's straight.

Now a laminated bar is a different story. You can't get the straight memory back by hammering them on a bare anvil. But if you lay a piece of thin rubber belting between the laminated bar and anvil you can hammer them out pretty straight.
But they usually don't stay straight for long.

yep, that's how i do it too, I hammer my own circle saws for the mill also. bars are easy. try getting the tension right on a 52" circle saw

You be a hammering fool tuning that blade.

I need a new brass hammer. My tree pounder is gone.

 

[tickbitintn]

yeah that'll buff right out...
lol

 

[Bilge Rat]

The hammer, anvil, and shim reminds me of tightening a 1911 frame/slide.
Did a few of those.

Having 2 anvils, a few pieces of RR track and over 50 hammers this method of repair is the go-to method.

If it offends you , take a hammer to it!!!

A hammer keeps most everything on a farm working.

There is a skill to knowing how/where , how hard and with what kind of hammer and anvil to assault the problem with.
The only claim i can make about using hammers is that i still have both my thumbs in working order.

If a hammer won't fix it....
It must be an electrical problem...


My favorite though is...
All you need is a hammer and a screw driver... If you can't hammer it....Screw it!

"Or get a bigger hammer". Lol

I've hammered a few of my older Stihl ES bars. Good hard rails, different quality then the Oregon, Windsors.
But don't laugh about that S bent Stihl bar. If I hold it down flat I could hammer those 2 bends out.
Can't guarantee the rails won't be all cracked up though.
