Lyman all American turret press knurled cap stuck

To file the threads, use a small triangle file and dress the threads one at a time. It will take a while but should work.

My dad may be able to find a die for it to clean them. He might be able to borrow one from his job as an oilfield mechanic

[TupariSD]

For future reference in case anyone needs to know the threads are 1-1/8"x28tpi

[TupariSD]

I chamfered the edges of the hole the detent ball resides in, because I noticed it was jamming inside, I won't be able to tell if this is helpful until we've repaired the threads (they're far beyond what I could do with a triangle file in places, I may have to order a used 1-1/8-28 die on eBay or something)I'm going to put a cut slug of brass rod stock between the lock screw and threads from now on, to prevent further damage to the threads in the future, as brass is softer than steel.

A piece of Nylon rod or a soft lead (think shotgun pellet or two) will be much better than brass, brass is too hard.

I am glad to see you got this figured out, my press is not coming apart. I hope I will not need to take it apart in the future!

[TupariSD]

FYI they don't make dies for that size and thread pitch anymore either, you might get lucky and get a used one on eBay, but it'll be from the 60's latest, I bought a used one and it snapped in half when I tried to tighten it(split die), so I had to special order one for $115, the cost of an rcbs 6 die turret press, but I'm hoping to recoup the loss on eBay. For anyone interested it's an outmoded thread standard 1-1/8 - 28 UNS(outmoded and replaced by the UNC standard), so if you damage the threads beyond what a 28 tpi thread file can fix prepare for quite a sum or to throw it out.

The threads could be single point cut on a lathe. I assume you have it fixed now or I would offer to buy it as I have the means to fix it. I also have one and it is my favorite press.

[TupariSD]

I hear it's night impossible to get the main cylinder out of the base.

[TupariSD]

And a lathe is even more expensive than a die

And a lathe is even more expensive than a die

But the lathe is much more useful.

But the lathe is much more useful.

Which allows you to save more money by taking on more gun projects,,,,,,,,

[TupariSD]

I don't have anyone to teach me how to use it. They don't even have vocational schools for machining anymore besides CNC

[rbuck351]

I already have a lathe and with a four jaw chuck one could center up the " main cylinder" by chucking on the base. Anyway, did you get it fixed? If not, I am interested in your boat anchor.

[TupariSD]

Yes it churned out .22-250 rounds like a champ yesterday
