Lee die disassembly problem

I‘am trying to remove a stuck brass in my Lee full size die. I’ve placed the die in my press , used the two proper size wrenches and cannot get the top nut to loosen or turn. I currently have the die in the freezer. The last time I had this problem, I gave up and ordered another one. Any last suggestions?

Wrap the die in something that will protect it and lock it down in a vise. Using a boxed-end wrench turn the top nut.
 
IIRC, the lee is intended to have the rod driven down with a hammer to drive out the stuck case. If the nut is that tight, the hammer may not work. What lube are you using? Just curious
 
The one time I had a similar problem, I locked the top nut in a vise and used an open end wrench on the die flats. Don't remember what it was. It was close to getting buggered when it let go. Next step was a big set of curved jaw vise grips. It will mess up how the die looks, but, it will still be functional.

FWIW, you can drill them out too. The stems are soft enough to cut flush, use a center drill to start. But, you need replacement stem/nut. If you have other Lee die the nuts are the same.

Yes, you can drive the stem down....if you can get the nut loose enough.
 
I hate Lee sizing dies for this reason. To keep the stem from moving it has to be tightened like you never intend to take it apart again, and then you have to take it apart…
 
I've never had this problem, how much force did you use to tighten the collet nut holding the stem in??

I tighten the nut "normally" and try a few pieces of brass through the die. If the stem moves, I tighten it a little more until it doesn't.

The Lee decapping stem is usually left with a slightly rough finish to grip the inside of the collet nut and keep it from moving easily.

If you can't break it loose, I'd suggest using a six point socket on it. If that doesn't work, send it back to Lee after calling them. They might replace it free of charge, they're good to deal with in that respect.

I think they offer a service to remove stuck cases as well, so they may just remove the case, polish the die and send it back to you.

Incidentally, I had a stuck case a couple of years ago in a Lee FL die (my fault) and I tried using the decapping stem as they suggest, to drive the case out of the die.
I have to admit, I was pretty skeptical about it A: working to get the case out, and B: the stem and die surviving the attempt.
It worked like a charm, and I'm still using the same die and stem today.
 
You don't need to remove the split nut on a Lee die if you use this: Frankford Arsenal Platinum Series Stuck Case Remover
Product #: 251956
Manufacturer #: 1078192
But I don't use it as the directions say!
I remove the die from the press, retain the stop nut on the die. I thread a 7/8 nut on the die. Add a bushing sized to reach the bottom of the die. Attach the stuck case remover, crank the Allen screw real tight. Place the assembly in a vice and use the 7/8 nut to pull the case out of the die. In other words turn the nut counter clockwise, the stuck case should gradually be pulled from the die with no damage to the die.
If you need a picture I can mock up the setup and show how it works.

If the freezer doesn't work, try heating it up.

Not cherry red under a blowtorch hot, just a gas flame on the die body around the nut for about 10 seconds or so. The idea is to get the die body very hot, but the nut not so much, so the thermal expansion difference will help disassembly.
