Unbelievable Trick--Freeze Shrink Metal Parts with Just Canned AIR?!?

[@LockyourHubs4WDing]

What other applications for air duster freezing can you think of?

[@Oz4me_craig]

Careful application to circuit boards, can show up the location of temp sensitive components or dry solder joints, helps isolate the source region of a fault.

Gee i would have paid a lot more attention at school if you where my science teacher. great video. Easy simple term to understand. Thanks that was awsome

[@LockyourHubs4WDing]

Cheers! Though I'm not sure I could tolerate that many teenagers in the one place like teachers seem able to do....

[@craigclarke1628]

Great work Simon. Practical science presented in an interesting way.

[@LockyourHubs4WDing]

Thanks! That's exactly what I aim to do.

Was looking for something to freeze a bearing down will def try this hopefully it will save me 1hr plus putting the bearing in the freezer. Thanks

[@LockyourHubs4WDing]

Glad to help, anytime mate!

I'm off to the Dollar Store to see if they have anymore cans of this stuff. I have rusted header bolts i'm trying to get off and curious if I can knock the rust off and shrink the bolts with rapid freezing. I only have one can and need more.

[@LockyourHubs4WDing]

That's a great application for this technique.

[@aaronhogan2371]

Looking forward to part 2 where you mig weld an external race to expand it.

[@LockyourHubs4WDing]

Hahahaha

[@smiththers2]

im going to try using this for installing ball joints on my polaris. i really hope the cold is enough to shrink them because its a press fit and i dont have the tools to press it back in. cant even get the spindles off the quad because ill def end up breaking other parts trying to do so lol

[@LockyourHubs4WDing]

You'll definitely get shrinkage using this method, whether it's enough, I'm not sure. Let me know how you go!

[@smiththers2]

@@LockyourHubs4WDing I'll have to heat up the aluminum spindles too, but not too hot because they will just drip lol...

[@ObscureStuff420]

I'm trying to get a tie rod end off that is stuck I'm thinking of blasting the bolt with this. Might also work on the ball joints.

[@LockyourHubs4WDing]

Either heat or cold should help loosen it up

[@ObscureStuff420]

@LockyourHubs4WDing yah I've seen people do both. I talked to someone who has used both liquid nitrogen and dry ice but the dusters are easier to find. If not I'll blast with a propane torch :)

[@MiniLuv-1984]

I bet the endothermic phase transition of the liquid can be turned into an exothermic reaction if you ignite the gas :) Like the idea of freezing a stuck nut...didn't think of that.

[@LockyourHubs4WDing]

Hahaha 🤣🤣🤣 definitely exothermic with a spark!

[@philg2468]

Maybe put the bearing cups in the engel at minus 20? I would have thought thats enough to make a difference. Might mean one less casserole on the next trip though

[@LockyourHubs4WDing]

That'll work, but this is quicker!

[@Falcon_Overland]

haha who needs a 12v fridge

[@LockyourHubs4WDing]

Exactly! Cold ❄️ drinks coming right up!

[@mickwolf1077]

Don't wanna be getting that shit in your lungs but I wonder how it'd go in an ac system

[@LockyourHubs4WDing]

Those sort refrigerant are what's in modern AC systems. They aren't as effective as old school refrigerants, though not as bad for the ozone layer.

[@mickwolf1077]

i ran LPG in my ac, worked great.

[@Bigcountry_littlelegs]

You won't have any issues with rust, as you end up with grease and oil everywhere

[@LockyourHubs4WDing]

Usually!

[@Bigcountry_littlelegs]

@LockyourHubs4WDing your in a heap of trouble if ya don't lol generally about 15km is when it starts lol

[@LockyourHubs4WDing]

🤣🤣🤣

[@lucysoutdoors]

looks like I need to add another can to the tool kit,Thanks 👎👎

[@LockyourHubs4WDing]

You're welcome!
