DIY Co2 thoughts on this one

[Dominick]

Here is something i work on Jet engines and we use Dry Ice to shrink
some of the metal parts its also "in lamence terms" compressed Co2
if you where to put it in some kinda sealed container how long would
it last?
mean i can get this stuff for free from work but is it worth it over a
sugar/yeast solution?
not only that it could serve as a multi purpose DIY Co2/Chiller lol

let me know what you think

From the threads I have read, it doesn't seem very feasible as a means of getting CO2 into the tank. Here are some previous threads:

forshortned version..
possible- I think so
practacal- probibly not unless you have the tools and some brazing and HAVC experiance.

greenmaji sums it up. sure its doable, but its not practical, and if you don't already have all the tools and knowledge, it'd end up being more expensive than pressurized CO2, let alone a DIY yeast setup.

 

[greenmaji]

the cost of a spair recovery tank alone is the same cost as a presurized tank and you still need the same gages and needle valve to use the CO2 for your tank.

bottom line is even if you have the tools to do it, CO2 gas is Cheap and thats the only product your going to get out of it (and it is going to be contaminated with air in this instance).. this just isnt practal at all (even if the dry ice is free)

sometimes I need to keep what I think I can do with what is practical in mind before wasting my time
