Thread chasers rethreaders etc.

[coolmercury]

I had a National, Jackson, Mich thread chaser for some time and picked the second one in a recent box lot.  Both are SAE and the National has one larger size.  Now to the second picture, I am guessing these are also thread repair tools, but have no idea how they are used.  Can someone enlighten me?

Got a car with a front spindle (or vintage car with a threaded rear axle) with damaged threads? Use the clamp on version, and clamp to the good portion, work your way out.

The thread files are nice tools. Practice on some bolt that you can mess up with a hammer tap. Skip to the 5:00 mark.

Those thread files have saved my butt more than once. I've always wanted one of the axle thread chasers but haven't ran across one yet. All good finds.

They are quite cheap at Harry Epstein -- US made by Wilde.

Good stocking stuffer (hint, hint)

I've got a pair of those thread files. They come in handy.

I'm currently trying to acquire a valve seat reamer and rethreader for hose bibbs. Most newer valve have replaceable seats, but alot of older bibbs don't. Sure, you can redress them, but eventually you remove all the metal. The kit I'm looking for cuts out the old seat material and re-threads the internals to accept new replaceable seats. Sounds like a "gotta have" kit.

I've got a few of the files in the box as well,  they were all duplicates my Dad had brought home from work when he retired.  I've used them a few times to clean up some threads.

Thread files are great tools that a lot of folks don't know about.  I had a damaged bolt or plumbing fitting a few years back and knew I had some of the files in the showroom for sale.  I went up and got one, it worked so well it never made it back to the showroom.  Second one has made it into my box also.  Just waiting on a Metric on to come through. 

I know there are at least 3 different thread files.  2 sae and one metric.

The metric ones don't turn up too often around here. I have one and it's the only one I've seen at the swaps.

Also if you don't have a thread file you can use valce grinding compound and a good nut.

Go very light on the compound as it can make things worse if you is too much.

That's a great idea, Muddy!
