Good video. I would add the follow if you want to be really safe 1. Don’t refill to more than 80% capacity, especially the larger size canisters 2. After refilling, submerge into water to check for leaks, make sure it’s dry before using again. 3. Mark RI, RII, RIII etc with each refill, I limit mine to 10 refills 4. Don’t put a winter blend gas into a canister for a regular blend. Winter blends have more propane
@@crazysquirrel9425 they’re not labelled as winter blend but are designed for lower temperatures by using a higher percentage of propane and sometimes replacing the butane with isobutane, for example Coleman Xtreme which can operate at -27C, but these blends will have higher pressures, so it’s important to refill the right type of canister
@@DavidDoyleOutdoorsI'm going to try refilling a 70/30 cannister with a 60/40 cannister (funnily enough the Coleman one you mentioned). I'm only going to refill it to 80% though. That's a really good idea re submerging it in water.
As a newbie to refilling gas canisters I found this video to be a very helpful approach to staying safe. Not going to attempt it until well versed in the subject.
Nice video Big Skies - I really like the graph you made, showing vapour pressure vs temperature. I'm guessing you have some sort of technical background? Cheers.
Thanks Joshua. Yes, I think that really illustrates the significant rise in pressure with heat. Definitely something to be aware of. As for technical background I dabble a bit in anything and everything!
@@bigskies2202 I was thinking about doing an experiment video, intentionally trying to explode a canister in an overheat scenario (safety precautions in place obviously). I've made some content somewhat similar to your own video in the past. I actually found your's on the stovaholics fb group.
I couldn't say for sure and wouldn't want to open myself up to guarantees. However the vapour pressure of 60/40 versus 70/30 is going to be something like 10% higher at normal temps. Given the operating range of temperatures the canister is designed for will almost certainly have some leeway I suspect you would be fine with a canister in good condition but would have to make your own judgement. A check on the gross weight of the canisters will give an idea on how much steel is in them. I.e. are the 60/40 built heavier.
@@bigskies2202 Thanks for your reply. No worries, I wouldn't hold you to anything 👍 Strangely the 60/40 gross weight is 351g whereas the 70/30 one is 381g. I'm in Scotland so it's likely I wouldn't be subjecting it to relatively high temperatures. The 70/30 cannister I'd be refilling is practically brand new, I purchased it last year. I think I'll give it a shot but maybe only try filling the 70/30 cannister to approximately 80% the first time. Thanks again for your response 👍
