Old Mechanic's Trick: Freeze-Shrink Metal Parts WITHOUT Nitrogen.

Happy Father's Day. This is a useful little trick to stow away in your Zombie Apocalypse file. You can freeze stuff down to 40 degrees below zero (either C or F) with a can of duster. It's also great for testing elecrical components and super freezing your buddy's beer.

Love it. Just used this trick the other day to test a temperature controller that was acting up. Needed below 0C but couldn't generate it with the wind tunnel down. Wouldn't have thought about it if it weren't for messing around with a can of it in the back. Every once in awhile a few of the loose wires in the brain box short and something miraculous happens. Simply amazing when horsing around gets valuable results.

[@syty747]

This is an old school trick with A&Ps, in fact, one of the standard issue tools they hand to us over here at Bombardier is a can of freeze spray so we can shrink panel screws and frame bolts that dont want to come out. works great on valve spring retainers that dont want to come out too!

Just about lol. Seriously though, sometime in January last year, maybe the year prior, my dad left a bottle of Jack on the porch. It was frozen solid the next day. It was -40C/F -52C with windchill that night. That's up north though, where winter lasts from about mid October to the end of April.

When I first started working as an engineer, the older engineers call that stuff "Technician in a can". We actually get stuff marketed as freeze spray though. Not sure exactly what the difference is, but it is helpful.

[@TheAmmoniacal]

Let me just expand on this.. When buying a can of air duster for cooling purposes, first find out what's in the can. Read the label or look up the MSDS (material data safety sheet) on the product. Some of them are just a butane/propane mix, which is very flammable - not something you would want cooling a PCB while it's powered on. But it does work for cooling. Ideally you want the air duster cans using CFCs (inert chloro-fluoro-carbons), this is the type of refrigerant used in A/C etc. It's not flammable.

[@russell6167]

Aaaaand many aerosols these days proudly claim to be CFC-free, what for not turning the Ozone layer into swiss cheese.

[@TheAmmoniacal]

Large-scale release of CFCs is not good for the ozone layer, but the amount used in household A/Cs and air duster cans is insignificant.

[@russell6167]

+TheAmmoniacal I didn't say it was significant, but, at least where I live, it's hard to find any aerosols which contain CFCs.. and the reasoning the manufacturers give is that isobutane and similar propellants are "ozone friendly"

[@danieljones317]

I used dry ice to plop sleeves into an Izusu 4BD2 engine I rebuilt. Getting the old ones out was a totally different story. You have to be a damn good welder to accomplish that!

srsly theres nothing like this in the EU dusters. Where do you get your dusters??

[@joshmx28]

In the US and I assume Canada dumb children would huff the dusters so they added some nasty chemicals to make the duster taste terrible. When used properly you don't really get it but when you turn the can over to freeze stuff it goes everywhere and you will be tasting it all day. I use it to remove mylar from pinball playfields.

[@oliverrapp93]

im pretty sure that any duster in the US is required to contain bitrex

[@axeavier]

actually no, it's just the US. There are NO restrictions for the beavers up north on when and who could buy the dusters. It's literally just a thing in the US and nowhere else. Edit: forgot the no part

[@MochuisleMocroi]

The propellant used in most of these air dusters is R-134a same refrigerant used in most car ac systems nowadays. It doesn't contain chlorine like most of your older refrigerants it's an HFC (hydroflourocarbon) so it's considered "ozone safe" just remember that this stuff is still heavier than air when it boils off it displaces the oxygen in a room. So don't use a lot in a small unventilated space.

Thanks for the video! Please keep up the great work.

[@rynomilner]

A temperature of +60 degrees C is indeed +140 degrees F, but a *change* of 60C is only 108F. You only multiply by 9/5, you don't add 32. As an example, a change from 0C to 1C is an increase of 1C and 1.8F, not 33.8F.

Back in the old days use to use the big co2 extinguisher from the shop (weren’t as afraid of fires back then) ya gotta take the big defusing horn off the hose (pocket knife will do) so you have a more direct stream of coldness but in a bind it’ll temporarily shave a couple mils off a part for ya.

If you cool acetone with dry ice, you can get it even colder than this. Dry ice sublimates at negative 78.5 Celsius, and acetone doesn't freeze until negative 95 Celsius, meaning you can make a very cold liquid bath. This would also probably end up being cheaper if you're doing this to multiple parts at once.

[@markdaniel8740]

[@mikefennema5561]

If you are brave you can use propane. Remove the orifice from your propane torch. Hold the cylinder up side down so when you open the valve liquid comes out. This will cool down to about -40 C. Only do this outside away from ignition sources. Can also be used to get rid of annoying smokers.

Having experience an empty CO2 Fire Extinguisher when I really needed one, then a second empty one, I can tell you that my reaction to someone misusing a CO2 Fire Extinguisher wouldn't be cool at all. Even CO2 must be taken in for recharging even if used just for a second or two. The valves will no longer be guaranteed to seal perfectly and it's very likely that well within a year it will be effectively EMPTY.

+animalmother556x45 the metric system is used world wide, which is not the case for imperial mostly used by the US. If someone have to change something, It's the USA.

Old Navy trick. Use a Co2 extinguisher with a big funnel nozzle. Put the part in the nozzle and stuff a rag behind it. Give it a shot and there you are nice and cold with dry ice.

this is a great trick, use it near daily when changing wheelchair wheel bearings

You can use dry ice crushed in acetone to get it to about -75c. It is much less volatile, and available at the grocery stores (well at least the dry ice is) Just don't put it in a sealed container. It's got to vent or you get some extreme pressured with it.

The "solvent" he's referring to is actually a refrigerant - R152a. It is an acceptable substitute for R12 or R134a. R134a used to be the refrigerant in there, too. Odd that it's illegal to release R134a into the atmosphere but it's fine to spray your keyboard with this stuff.

Good old Joule-Thomson expansion.

That propellant is awesome amounts of flammable.

[@brotherlove100]

that was a good tip. I can't imagine what the whole thing would have looked like

If you take a paper towel/shop rag and run it under hot water and wrap it around the can, the can will blast for longer. The same effect that you are taking advantage of (It takes more energy to go from a liquid to a gas) is what lowers the pressure of the cans as you use them up.

You can buy cans of freezer spray (here in the UK anyways) that'll do the job without leaving that goopy mess. Freezes right down to -35°C.
