Imaginative repurposing of now redundant Calor gas bottles? :-)

[LittleSister]

What imaginative, useful or plain daft alternative uses can forumites suggest for the now apparently redundant* Calor 4.5kg and 3.?kg bottles?
(*see Calor 4.5 Butane and 3.5 Propane to be discontinued)

Thinking caps on, folks!

Virtual prizes galore on offer for the best (and worst) answers!

Along with old (steel) SCUBA tanks make a mini wood burning stove, go careful with the angle grinder though...

A slightly harder hat than your regular tin foil hat.

When changing to Portuguese cylinders I left my somewhat larger Calorgas cylinder, empty, (14kg?) next to the marina skips. Some one found a use for it as it disappeared after a couple of days.

Could I point out that you can never own a Calor cylinder, you only rent them. Disposing of them other than to a registered Calor dealership or repurposing them for your own use is theft.

Or make a mini version of my Mass rocket stove stove which was part of a 47kg.

Kicks out big heat, burns atleast 50% less wood and smoke free

I consider taking a cylinder fee and then never ever offering a refill over three years and refusing a refund to be theft. Each to their own.

Hey, don't shoot the messenger dude!

One enterprising company on an industrial estate near us has "repurposed" a BIG C**** gas bottle.
It now stands on a steel column outside his industrial unit. Resplendent in bright Blue and Yellow , a rather good likeness of a Minion !

A slightly distant neighbour has cut a slit in his and uses it as a letter box.

I fished one up once (the toe of our anchor caught into it), it was full of scrap metal, it sort of rattled, metallically, and seemed to have been used as a kellet. I did not investigate how they got the scrap steel inside.

Or, coincintally, obscure support for Ukraine.

What about fishing floats for creel fishermen, there could be a wee gas light on top if there was any gas left, so easier to spot in the dark

Don't give them ideas!

What about anchor buoys to mark the end of your tripping line, we could then merge this into another thread

That looks good though not quite sure how it operates....... publish or be damned......!

 

[Refueler]

I know people who use them as Compressor pressure vessels (low to mid only of course) ... paint spraying as example to smooth out the pressure delivery to 'gun'.

I've seen cylinders sliced in half lengthways and turned into a barbecue.

ha ha i publish then as i do like to pop in now and then

First chamber/fire box is well the fire box where the wood goes in.
the burn tunnel which is tapered to a riser tube which makes the fire into a vortex. at the bottom it has a secondary air in take which burns the gasses int e vortex. hot air goes up the riser tube then down inbetween that and the outer ( gas cylinder ) heat exchanger.

then out the flue at the bottom.

Temps get to 460 Deg C in the fore box, heat exchnager to 230Degc. Flue max 70 DegC. I can modfidy it to get more heat out but in the shed is a T shirt job when its -5 outside so gets a bit warm.
In the riser it can get to 1200Dgec so i need to make aproper fire brick rise soon as this is made from 6mm steel which i am seeing how long it lasts.
It burns less wood as it also burns the gasses more than the wood.

I've bought the hose and will be refilling them forevermore.

I have two - a small one and a big one on wheels - for inflating tyres that are nowhere near the compressor. Really handy.
