Co2 Cartridges

How about an accumulator for a small hydraulic model?

The casing of these little cylinders is (at a guese is somewhere about .025"/.0390", have not actually measured one. Saw one use in a shop in town that sells some doubtful items, about 10 mm of the base of one brazed on the side of a second one, and a hole communicating between the two parts, looks like a little smokers pipe, yep, a bong, and all nicely chromed.

  Used one as a pressure vessel on a little water pump.  Also used a CO2, and a slightly larger niros oxide one to make an oxy ascetylene(?spelling) set for a model workshop.   Ian S C

Scallop a piece off the fat end. Add a handle and you have a superb ladle for hot lead or hot most things? Works beutifully!!!

spent bulbs make decent handles for files

Further thoughts inspired by Axel's excellent ladle suggestion above:

On steel cyls that are empty, the necked end could be cut off, the cylinder cut in half lengthwise, and a wire handle welded on to make a nice firing shovel for small models with a round or oval firedoor. The hemisphere shape of the back end might be easier to get back out the door opening if it went in too far and dropped. The flat backed ones can be a pain to get back out. Front corners can be radiused to suit.

Just food for thought.

Bazyle asked earlier fo a use for plastic milk bottle tops. I was just about to throw one away - not sure if the tops are re-cyclable here- when I thought they would be ideal for mixing small quantities of flux with water. I usually use a yoghurt pot or similar and always end up making too much - hopefully this will result in less waste in the future - Bob

I would guess the cylinders are made of aluminium

All the small cylinders I have used are steel.

I have both

Surely these are still used to operate small CO2 engines for indoor model aircraft like the Gasparin, Telco etc. These motors are provided with a clip-in mounting for these cartridges. Offer them on the BMFA website. You might get a bob or two for them. TomOl.

Why not paint little faces on them and stand them in your workshop to scare away all the goblins and pixies that come in the night and move/steal your tools?

I have some plans for a model gas turbine which uses empty CO2 cartridges as the ignition chambers. Each has a glow plug in them and the motor revs at around 30,000 revs. Never got round to it because of the problems in making the compressor and turbine rotors.

I can acquire a few from my gun club if any body needs some? In the weymouth area!!!!

Bob, one of the earlier gas turbine models, made by a German chap ( ??Schekling), had a centrifugal impeller made of plywood, I think I would try recycling the innards of an old automotive turbo charger.

The wooden impellor worked since it was in a flow of cool air, and was a lot easier to make than milling from a solid piece of tough metal. Turbo charger impellors from cars were widely used later, the particular one which was popular was from a Porche engine. Bearings were one big problem at the speeds and the temperature involved. The use of ceramic bearings was the big break through. TomOl

The gasparin adapters use the smaller sparklet sioze, not airgun size.
