Topic tags/keywords: plane thread repair threadmate mate

I picked up an old Stanley-Bailey #7 off of E-Bay a couple of weeks ago. It was very rusty and took a lot of WD-40 to get everything apart. In the process of restoring it, I found that the threads on the lever cap screw and the adjusting nut screw were all boogered up. Normally, I would chase the threads with a die, but I was unable to find a 9/32”, 24 TPI die in either right or left hand thread. There appear to be plenty of replacement lever cap screws available around the internet, but the LH adjusting nut screws seem to be a bit rare. However, I stumbled across a gadget called ThreadMate and decided to give it a try. This thing worked beautifully. It does both the right and left hand threads. You just swap the blades around for the left threads. In ten minutes last night I had both screws turning like they would have over 100 years ago.

I thought I’d just post a little note about it here in case someone else has the same predicament. This gadget might be worth a try.

Glad to read the external re-threading tool worked.

LOL
Sources for Stanley Frog/Tote tap/die are listed everywhere!

Wayne has it summarized in his blog
https://www.lumberjocks.com/WayneC/blog/38068

and Don W also has it on his blog and web site. :)

Victor also sells a 9/32-24 tap for lever screw,
Now if Stanley plane restorers could just find that elusive 9/32-24 die made today …..

Wait – before you leave, there is another trick to fixing Stanley Plane threads:

If you are lucky enough to own an old Well Brothers tap/die set, the kind with the adjustable thread inserts, you can make both 12-20 and 9/32-24 threads. They look like this:
http://www.vintagemachinery.org/photoindex/detail.aspx?id=36213
Except you want the set with FINE threads to get 5/16-24, not standard course thread set.
Warning, They are somewhat scarce in used market and fleabay prices can be unreasonable. Most often seen in east coast US flea markets near where they were made in MA.

Just use the 1/4-20 die closed down slightly for 12-20 threads and 5/16-24 closed down to make the 9/32-24.

Wells Bros ‘Lil Giant’ brand also sold 9/32-24 standard round dies. If you can find one of the old round die sets with fine threaded dies in used market, then you have same tool used back when Stanley make planes in USA. :)

If you simply need to clean up old buggered threads, you can have some luck with 5/16-24 standard round style die, if your die holder provides enough force to close the die to near 9/32. I used this method for 12-20 screws using 1/4-20 die before I found my Wells Bros Lil Giant die set. :)

Best Luck.

LOL – Might be surprised?
Just looked and fleabay is flush with Lil giant die sets ATM:

There are several #5 sets listed that have the 1/4-20 die.

Found a set with both 1/4-20 and more rare 5/16-24 listed by habitat for hummanity in CA,

Oh wow, found a set without box and both ‘Stanley’ dies for <$15 right now:

Just have to know what look for, try ‘Little Giant Tap Die Set’ in search box. :)

Cheers!

Do most of the sets have the 1/4-20 or just the little giant ones?

I contributed to the info on Don’s site that came from my blog and he expanded on it. I think I had links to some that were less expensive than the long term ebay seller (NICOBE?) or St. James Bay. Looking at it, the links were the victor links. I also bought a bunch of drill rod on Amazon to make tote and nob rods. I should look at getting the other size tap and dies.

This whole discussion got me wondering if I could make a 9/32” die. It looks like I’d first have to make a 9/32” tap. Maybe I should acquire a small metal lathe. Hmmmm…...

That’s one thing I don’t need is Stanley tote rods. I have more than I need. Some of the short rods for the front knobs I might only have a couple extra. I read Dons article on his site.

The secret to why the antique Little Giant die sets work:
There are 2 threading dies, opposite each other.
Can adjust the position of them, closing the gap to create a #12-20 thread (0.2160 OD) from the 1/4” (0.250) dies. Same goes for the 5/16-24. You can close the gap between the individual dies and make 9/32-24 thread. The threads will not be a nice tight class 3 fit, but they will work for silly old Stanley plane.
https://en.wikipedia.org/wiki/Unified_Thread_Standard

BTW – when I am setting up my 2 piece dies for odd size, I use a non-damaged old Stanley threaded part to loosely set the diameter. :)

The normal round threading die sold everywhere today are ether fixed diameter, or you can only pinch one side of die and make a smaller thread. If there is enough space in gap die, you can do same thing. Trouble is I have never been able to get die closed enough with modern style dies.

YMMV
