Some ideas I came across today. Fixing buggered threads.
Anyone every used stuff like this? Thread file for fixing
threads.
PRODUCT OVERVIEW
Model # 33024
Internet # 205215048
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.
Used to restore damaged or worn external threads on bolts,
pipes, etc.
Each thread restoring file will work with 8 different thread
sizes

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 used a thread file before i got split one and hex die set.
File works pretty good if thats all you have.
