Well, this is the first time I have ever seen this. While working on my flaps the other night, I was happily riveting the top skin to the spar, and I noticed that my bucking bar felt....weird.
I keep it wrapped in athletic tape to make it easier to handle, and to keep it from scratching my surfaces on the non-bucking ends. But after about 20 rivets or so, I noticed it felt "floppy". After un-wraveling the tape, my heart sank just a tiny bit. One of my favorite tools had given up the ghost...
Here's what it looked like with the tape on, and slightly "floppy":
And a close up shot of the break itself:
This was from an Isham took kit, so I sent off an email to see if this might be covered under some sort of warranty. I sure hope so, considering these things are $130+. It kind of looks like there is some contaminants in the tungsten when it was made as you can see the specks in the photo.
Has anyone else ever had one of these expensive tools break on you like this?
