Seen Another Cracked N14 Bolt

[painter777]

Monday morning after coffee I headed out to my local range, finding only 1 other guy there. I noticed he had a carbine on the bench, so we got to talking.
He said he had just got there a few minutes earlier.
I laid my gear on a nearby table and went over and signed in.
Pinned up a few targets and pulled my carbine from it's case.
He seen it......... we talked again, showed him mine, he showed his to me.
His was a NPM, that got me to talking about how many N 14 bolts that I'd seen over the years. Sure enough while I started to show him where the cracked lug is usually seen....... I could see his was cracked. It looked like a scratch, but looking closer you could see the crack circled around the rear of the right lug. I bring a small parts/tool pouch with me and loaned him a extra bolt that would work, so he could send some ammo down range. He had his share of FTF and FTE, besides that carbine begging for a thorough cleaning, I seen he was using old ammo with the French or Italian head stamps. He'll bring it over this weekend and I'll go over it for him. Overall it ended up being a decent day. But really gets you to thinking about making sure you look these over on a more than regular basis.

I borrowed this picture from a recent ebay auction which also happens to be a N14.

How could one miss that as that ain't no scratch I can even see it down the back face of the recoil lug crikey that would just about be staring you in the face lucky boy you were there Charlie hopefully a good friendship will ensue.

I know that feeling Charlie see pic of my Savage bolt that cracked being a 6.5 x 284 there was allot of horsepower in front of my beak discovered by shear accident thankfully.
Upon extracting a fired case the bolt kept knocking the safety on as it sits at the rear of the bolt race I now have a much beefed up after market one all thanks to Brownell's Australia awesome to deal with.

Cinders,
That is a example picture of a broken N14 bolt, I BORROWED from a Ebay auction. Not His bolt.

Look at my reply #14 on page 2 showing the hairline crack I found on my N14 bolt.
His looked just like mine... looked like a scratch, until seeing it out in the sun light.

It feels good to helpout another carbine guy. Nice going Charlie.

The Norwegian army and police changed out all the flat bolts on the carbines with round ones, becouse of some of them was breaking. This makes it easy to find nice flat bolts here.

It wasn't just National Postal Meter that had bolt breakage problems. The type 1 bolt was very prone to breakage and that led to the type 2 to add a bit more support to the web for the extractor. As we know it did not cure all the problems and many type 2 bolts broke too. That did lead to the type 3 also known as the round bolt which was beefier in the extractor web area. Not that it was a cure because a few type 3 bolts failed.

I had a pristine Underwood type 2 bolt crack and break at the web while shooting with USGI ball ammo years ago. Took awhile to find a just right replacement. I stopped shooting any of the collectables I had then and they just sit in my safe now.

That did lead to the type 3 also known as the round bolt which was beefier in the extractor web area.

The round bolt is not " beefier in the extractor web area". That area is the same as the second variation to the flat bolt design.

Hummm well I must have assumed that is was a few thousands thicker then the type 2. It was heavier and it did help with the timing and dwell of it's travels.

I could post another picture of a cracked N 14...but it would look EXACTLY like the one in OP's post #1. Cracked in the same place. Mine broke day before yesterday.

It would seem to me that this failure was/is occurring on the closing stroke of the slide and not the opening stroke. The front of the lug and the web is not molested....the crack is directly behind the extractor opening.
