tapered thread rethreader

[uasrs]

I'm needing something to clean up the threads on my 47 Champ rear axles. I haven't seen a die big enough. I've seen pictures of an old tool that would do it but have never seen one to buy. Any of you run into this and is there a place in central Arkansas to maybe rent something?

Mac tools sells a variety of spindle rethreaders. No doubt Snapon does as well.

I bought one from Dan Webber a year or so ago, if all else fails...

I'm ASSuming that having in my possession the correct tool will ensure that I never strip another axle shaft

Not familiar with 47 but if it is the same as later axles it is a 7/8"-14NF nut. A die could be found at any industrial supply house such as
Fastenal or MSC. Don't have a Sears tool catalog handy but should be available there as well. NAPA is probably another source.

If thats the correct die I will be happy to pick you up one here in SC and ship it to you at cost. I have to go to the tool place tommorrow anyway. Steve

I bought these at an old tool sale last weekend. I think this is what you need.

this is more like what I have

it doesn't care what the diameter of the part is that you're chasing the threads of, only the thread form and pitch.

I had a Stude axle with bunged-up threads awhile back, and I took it to a local machine shop. It wasn't too expensive, and I felt better knowing the axle nut would hold.
Be sure to look closely at the axle nut, too. The threads in those get squared off, and the nuts can developp cracks from all that torquing. I've found nuts with the same threads at specialty hardware stores, but they were too thick The cotter pin would not go through the axle). The correct ones are available from Stude vendors.

I have a thread chaser like in Nate's link. Not sure the one I have will work on something as small as an axle end.(maybe). I use those on full-floater axle tube ends where bearing nuts go. The thread chaser Ann pictures looks like the thing to use if it has the right size dies in it if threads are damaged to the point a hex is difficult to start. Those can be install behind damaged threads and worked outward to damaged part of thread.

I have always found thread files to come in very handy for these tasks. I have one for Coarse threads and one for Fine threads.

For what it's worth, and that's probably little[:I] I thought I'd add my two cents worth. My trade, (Journeyman), we studied all the threads of industry;

Whitworth - English, a course thread mainly used for industrial bolts.
SAE - USA, Society of Automotive Engineers. A fine thread used on cars.
UNF - USA, United National Fine. Similar to SAE, but just a little different.
UNC - USA, United National Course. The same as Whitworth in all sizes except 1/2".
BSP - English, British Standard Pipe.
NPT - USA, National Pipe Thread.
Gas - English, for small size pipe threads, mainly brass fittings.

These are the main ones used but there are many more, metric of course, and many bicycle mfr's used their own threads. The main difference in threads is the angle of the actual thread form, and the pitch - the number of threads per inch, (TPI). As mentioned before the Whitworth and UNC are similar except in 1/2". Whitworth is 12 TPI, and UNC is 13 TPI.

Especially for an axle that someone has mushroomed the threads on, I used a thread chaser that you clamp around the axle. Start at the inner end of the threads and work your way out to the end of the axle. I also believe in using a new nut afterwards. I have done this with good results on Studebakers and Mopars.

Matt, UNC threads are 60 deg. included, Whitworth are 55 deg. In addition to being different pitches. I had to make adjustment screws for a British 4 jaw chuck once. It took a while to get organized.

In case this hasn't been previously mentioned - Never use a die to chase a thread! The die removes too much metal virtually guaranteeing a stripped thread later on.
