Some ideas I came across today. Fixing buggered threads.

Anyone every used stuff like this?  Thread file for fixing threads.


PRODUCT OVERVIEW
Model # 33024

The Nicholson 4-Piece File set contains an assortment of files that will help restore damaged threads to a useful state. Restoring threads on damaged and worn bolts and pipes can help lengthen the life of each. Files come in a canvas pouch for easy storage.

    Each thread restoring file will work with 8 different thread sizes
    Type 2 red cap: ex. fine/ex. coarse bolt; 9, 1, 12, 16, 2, 27, 28, 32 tpi
    Type 7 green cap: regular pipe; 8, 1, 11 1/2, 14, 16, 18, 24, 27 tpi

Looks a little crude in the video. I'd run it through a die instead...

Thats my thoughts too.

What about left handed threads.

Also pogo was talking about a file type string thing that his NAPA dealer used to straighten out the threads on the end of a crankshaft. Any idea?

Kev, left hand dies are available and not that pricey.  Adam Artzer bought one recently for a 3120 that the crankshaft shop booger'd the threads on somehow. Two piece clamp together dies work well when the lead-in  threads are trashed.  You clamp the die on the inner thread area and back off to clean up...

Split die thread chaser is the proper name I believe.

I have used thread files before. I think they work good. Seems a little bit of a cheaper route to go then buying dies. I agree with Adam a die is going to give a much better result.

I've used triangular files in the past.
