    Pineapplerose found this one and mentioned it here

    Gas Pak


    Sooty's kindly made me it's new custodian and here are a few initial shots after taking delivery of it today.

    Fuel is from a Ronson blowtorch, now obsolete as a fuel source but that's an unused can and the Gas Pak will enable me to refill the cartridge - but more of that in the 'Frankies, Mods and Hybrids' column in due course. Svea 123 included for size comparison of course

    Thanks again Sooty!

    What a smarty you are, I am so pleased to see it working, that is quite a flame thrower. Does it need a simmer plate to disperse the heat, looks like it will burn the arse out of the coffee pot. It's former life may have been in a dental technician set up.

    If it had stayed with me it would have just ended up being used as a prop for photography, it is such a lovely shape.

    cheers Sooty

    Looks heavy with all the brass and steel?
    Powerful little thing.

    That's quite a flame it has there! Surely there are butane canisters compatible with it? Perhaps at a Tobacconist?

    G'day sootyfingers,

    I never thought I'd see the day when your old gas pak made it to these shores, with John, it's certainly in good hands, he's sussed a way of re-filling his cartridge, whether it's of a type which is obtainable out of a tobacconist is something I have no knowledge of.

    Looking at it's flame, it's similar to one thrown out by an old rechaud bleuet can gas stove, looking at it, it's quite likely to have been popular with backpackers, scouts, cadets & cyclists.

    Definitely a rare beast, best wishes=Johnno.

    ------------------------
    If in doubt, brew up.

    Working week over, I've had a bit more time to tinker with the stove tonight, which included looking more closely at the hose connection and fuelling arrangement, hose disconnected here

    1367606551-12.JPG


    The Ronson butane cartridge I've been using is only an approximation to the long-obsolete Australian original brand. It takes the stove's fuelling hypodermic needle, but the black sheet metal spacer mounted on the control valve ...

    1367606567-13.JPG


    ... doesn't match up to the dimensions on the Ronson cartridge, so doesn't offer any support

    1367606647-20.JPG


    Pity, because removed from the control valve it fits the Ronson cartridge's support boss

    1367606635-19.JPG


    By unscrewing the needle injector from the control valve the spacer/support can be removed

    1367606574-14.JPG


    There's a rubber seal inside the needle mounting nut ...

    1367606583-15.JPG


    ... which makes a seal even hand-tightened

    1367606592-16.JPG


    Impracticable as a fuelling device without a spacer/support, since it's just too vulnerable to knocks

    1367606613-17.JPG

    1367606624-18.JPG


    Constructing a taller spacer/support would be one option to retain the needle fuelling from a Ronson cartridge, or, using the control valve taken from one of those Chinese-sourced flexi-hoses and control valves to fit screw gas cartridges, bought cheaply as a spare for the Chinese TK-something stove

    1367606726-25__2_.jpg


    To make use of that screw-fit control valve I'm relying on a useful feature of the Gas Pak, which is to use a couple of these ferrules ...

    1367606688-24.JPG


    ... to make a secure, gas-tight connection at the control valve and stove

    1367606657-21.JPG 1367606667-22.JPG 1367606678-23.JPG 1367606714-25.JPG


    By soldering a small length of brass tubing to the screw-fit control valve's hose barb, I've bulked out the diameter of the control valve fitting to suit the Gas Pak's hose

    1367606740-26.JPG 1367606757-27.JPG


    Alternative fuel source, but with the conversion readily reversible to install the needle injector control valve to keep this old butane stove original and authentic

    1367606771-28.JPG


    A side benefit I had in mind was to create a refuelling rig for the now-obsolete Ronson gas cartridges

    1367606784-29.JPG


    It lets me keep another old-timer from the tool cupboard running and that's good because there's nothing quite like the Varaflame feature for achieving the optimum size of flame to heat soak a (small) component for soldering or sil-brazing and simply feed the solder wire or brazing rod into the joint

    Tried my hand at producing a waterslide transfer, tidying up an image of the worn example on the stove ...

    1416953254-2.JPG


    ... to get onto a sheet of waterslide transfer paper for a laser printer

    1416953284-32.JPG


    Off with the old ...

    1416953309-33.JPG


    ... and on with the new

    Ian, the waterslide transfer looks great, especially on the stove.
    You mention that you used a laser printer.
    After you printed did you coat the transfer with anything or is the laser printing stable?

    Hi Trevor.

    A feature of the laser printing transfer (decal) paper and a laser printer is that there's no need to seal the surface with an acrylic varnish as is the case with the bubble-jet paper printed version.

    Same end result in terms of durability and finish I expect, but I'd the use of a laser printer so I went for that option.

    John
