Stripped Threads--Quick fix

[lakngulf]

First law of using brand new equipment--tighten all nuts and check them often, then check them again.

I bought a new chisel plow this year and it worked great to break up pasture land for food plots. I forgot to double check before each use, and one of the bolts holding a spring loaded chisel lost its nut and almost worked its way out. I was able to pry the plow enough to drive the bolt back in, but, of course, that stripped the threads so that the nut would not start. Had work to do so just kept going and stopped often to drive the bolt back in.

Finally, I was able to bring it home to ?fix?. Well, I could not figure how to release enough tension on the springs to replace the bolt

So, I tried another approach. I drilled a hole through the bolt large enough for a cotter key. I realize the key might break, but maybe I have learned my lesson and will check it before and after each use.

By the way, how does one release the tension on those springs?

Chain from the spring attachment point to an immobile object. Pull gently to counter spring force.

Looks like an old fashioned brake tool would work. You remember- the ones you use to work on drum brakes to remove and replace that retaining spring holding the shoes together.

Thread file might let you repair it in place.

I was able to get out of a jamb using my thread files. There was a burr on a bolt I had to reuse, and none of my taps fit. One edge of my thread file was the correct pitch, so I was able to clean the threads back up. I have two thread files, one SAE, and one metric. Combined, that is 16 pitches covered.

Sounds lkie you have the same set I have. Double ended, four sizes each end.

It sure does. I don't get a heck of a lot of use out of them, since I will us a tap or a die* in any case where I can, but I do value those thread files for all the other cases.

*In my post, I said none of my taps fit. I should have said "dies."
