After breaking the bolt off my new DAPNet logging hook, I had a student at the local tech center go to work on it. He replaced the broken bolt with a new grade 8 bolt, shortened a bit. The result is an excellent tool, light and much stronger than the original. I have used it for about a week now, and it is great. That small change makes a huge difference!

Did the student weld the grade 8 bolt? If so, I am curious to see how it holds up as I have not had luck with welding grade 8. I believe the heat from the welding process destroys the temper/harness in the bolt and it becomes much weaker and more brittle. I have had better luck sizing up (i.e. 3/4 to 1″) and using mild steel. I have also had luck with cold rolled.

Yep, he did. And we talked about that in the shop. He got help from a tech welding instructor, so we will see how it holds up.

Hi George and Brad, I am glad this is working. let us know when you feel you have really tested with big logs and stuck logs and such! This is great news. At this point there are quite a few of the original ones, but not everyone will break them, and I don’t mind taking them back and fixing them.
I think this application is particularly well suited to welding the grade 8 bolt becuase the weld is not what was to weak or broke. I think Brad broke the head off the Bolt (There is some torque there). But there is plenty of welded area, and I don’t think they will brake there.
I am glad you like it. I think they work great for the first goal, making them easy to pick up for beginning teamsters.January 22, 2015 at 7:10 pm #84678
Had interesting event today. Was working my team in loose rigging with DAPNet hook. Got onto a big stick of maple with three logs and firewood on the top. They began to move it, but one of the trace links on my mare’s harness shattered at the weld. I have never seen one of them break. Has anyone else ever had that happen? In any case, the hook did not fail, so far so good…
