Hey guys. I have nest of boxes brass and one of them are stuck. Does anyone have any ideas on how to open or separate them without damaging the brass box?

Sometimes you can loosen stuck parts by cooling then heating them. What I'd try first is to turn them upside down and tap firmly on the bottom.

Thanks Ray. I've tried the tapping firmly but nothing. I'll try the cooling then heating method. Meanwhile if anyone else has any ideas I'm all ears.

Can you spray some penetrating oil (like WD-40) into the box or under the lid?

Heating the whole box probably won't help, but if you can figure how to heat just the top, that would be best. As you'd only want the top to expand away from the bottom.  I know the boxes are small, I have a nice Viking set, but that rubber jar opening pad (tacky rubber disk) may give you  a better grip. You'd probably need 2.

Have you considered taking it to a local, privately-owned machine shop? (Assuming there's one near enough.) I have a nice Okito Box, probably 35 years old. I dropped the lid on the floor and it must've hit just right since the lid had a noticeable ding and would no longer fit the bas. Took it a machinist, he looked, said, "Give me a couple of days to get to it" and fixed it right up.

Try putting the stuck set in the freezer for an hour. It'll heat up quickly when you remove it, so any action you take has to be immediate. Maybe wrapping it in a towel and then tapping the wrapped item on a hard surface while it's still at a low temp. Worth a try.

Different shapes are going to be affected by different amounts. It's not clear whether heating or cooling is the way to go. If cooling fails, try heating.

There's a classic physics experiment where a brass sphere won't fit through a nut. But when both are heated, the sphere falls through. It's because the different shapes expand differently.

So I've tried everything you guys have posted. Cold, hot, towels and found one of the craziest methods to work. Butter knife opened it up. Had to be extra careful. Found a few pocket lint stuck in the creases. Thank you everyone for all the advice and help.

Glad it worked out.  So was the lint the culprit?  Is there a chance of it happening again?
If the tolerances are that tight, perhaps you need to have it addressed for future use.

I would also think that keeping them brightly polished will help.  When brass or anything similar corrodes, there is a film that develops on the surface.  That film might be adding just enough friction to where it hinders smooth operation.

9 out of 10 times I keep them polished and clean unless I want them to look old fashion. But in this case i missed some lint. Could it happen again ? I don't see why not. But my guess is to make sure it's always clean, which would include any of my brass items I put or use in pockets. You never know what could happen if you don't check you brass items before performance. Not that I use them that often, but sometimes it's good to have them around.
