For a full run down on this project and rules please go to: "The Patriot Woodworker and MWTCA "What's It" project"

• Only Patriot Woodworker Members are eligible to participate and receive the award.
• The MWTCA only accepts a verified source to support your answer, so one should be submitted with your answer, such as a patent, catalog entry, tool book reference, or a respectable website on the subject. Do not let these requirements prevent you from having fun and submitting educated answers on the subject without verification, we can worry about references later. All answers are welcome, as well as healthy debates regarding "What's It".
• If a verified and referenced answer is not arrived at by the end of each month's "What's It" project, a random draw will be performed for a "One Year MWTCA Club Membership".
• Only Patriot Woodworker's who participate in this "What's It" topic will be included in the random draw.

Thread chaser for straightening out threads that have been damaged.

Sure looks like it, Dragon. 

Did a Google image search for that pic. Ya know, Google aint all that smart.

Seems a worthy description to me.  Maybe used by a pipe fitter on a specific size of pipe.

Yep, from a Journeyman Pipefitter. 

...Looks like a 1". Also handy for reforming out of round pipes.

It would help to know the diameter and TPI, straight or tapered.

It seems that the answer was posted and confirmed.  Great job, all.

I would agree with the consensus but what is the cup end for?

I wondered the same Gerald.

Some were made to accept a two piece insert that would do a smaller size.

The insert fit into the groove visible in the top photo.

There should be a notch about center that I can't quite see, that keeps the inserts from spinning in the groove.

There was a set of these in the shop that I was told dated from the 1920's-30's.

That would have been the Nash era for our plant, and way before my time.

I don't remember seeing a brand name on them.

Man I just don't see it.

So exactly how does this 'thread chaser' thing a ma jig work? I've seen hand held thread chasers before and typically they are only one thread cutter or two, or three, not the multiple threads you see in this example, that would be very hard to plow through specially with those very short handles, hardly any leverage at all. Now threading machines for threading pipe have rows of threads to cut and clean as it goes, but hand held thread chasers to re-groove threads, typically one cutter or just a few.

 

Just think about it, with the tool you see above, you'd have to clamp the tool down on all threads at once, and with damaged threads, how lucky are you going to be to hit all the threads correctly?

John,

They weren't the easiest thing to use. They actually worked better for reforming the end of pipe that was slightly out of round. In that use you had to get one side to align with the threads, and hope it didn't damage the threads further when you closed the handles. You had to get it started from the end threads for chasing the threads. I much preferred using a hand die myself.

If I remember correctly the largest size these would handle was 1", with inserts for smaller sized pipe.

Some of these early tools were a good idea that weren't really practical in use.

For those that question, think of it as being able to go around a pipe or threaded rod. Back in the old days it would slowly straighten out the threads, not cut them but bend soft steel back into undamaged shape after cutting the rod or pipe.
