    With a birthday imminent, I was asked by my immediate family whether I'd prefer "a surprise gift or something you'd really like to choose for yourself?"

    No contest, I chose this

    The burner parts

    Fuel cock and fuel cock to tank adaptor ring

    Pump and non-return valve components

    Tank, enamelled windshield and pot rest 'superstructure'

    The burner in process of assembly

    Here's the burner cap with the gauze lining to prevent flash-back/underburning

    1304632730-17.JPG


    A comparison shot here between the Tilley stove vapouriser/generator and internal pricker wire (about three-and-a-half inches long - 9 centimetres) and a Tilley vapouriser and wire from a PL53 lantern, the lantern vapouriser and wire being about twice the length of the stove's.

    1304632756-18.JPG


    With replacement vapourisers for the Tilley stove being virtually unobtainable, I've a plan in mind to cut down a readily available lantern vapouriser and pricker wire to size, silbrazing the adapted components together. There's one significant issue however, and that's the greater jet orifice diameter of the stove's vapouriser, evident from these photos

    1304632776-19.JPG

    1304632794-20.JPG


    Food for thought about constructing a spare vapouriser tube - oh, and a Vapalux-type priming cup to construct too - but meanwhile I'll reassemble the stove and post some photos of it fired up, shortly.

    Hi John, first of all happy birthday when it comes and what a great choice of a stove and not too common, in fact quite hard to come by.

    On another note, brilliant documented thread and write up. These stoves I must say are really interesting and have some great features like the burner cap gauze lining to prevent under-burning. The only snag with the Tilley stove is it has a seperate flame system to keep the vapouriser hot enough to vapourise the fuel so a little extra fuel is used on this process. But still more economical to use than a gas cartridge stove and when lit it gives a more interesting flame pattern. I am looking forward to seeing this fully fettled to your very high standard and running.

    Many thanks for the best wishes all ...

    Well, it's not my birthday just yet, but I'm having a lot of fun with this Tilley already.

    I decided to have a go tonight at making a 'short' stove generator out of this candidate, a well-worn vapouriser from a PL53 lantern

    1304719113-1.JPG


    Yes, a ropey old thing ...

    1304719121-2.JPG


    ... but with a brass screw fitting, which I prefer to the economy steel version in later production runs of Tilley vapourisers

    1304719130-3.JPG


    I cut the tip off first, then a section of the middle section so that silbrazing the tip to the screw-mount part gave me a vapouriser of the right length

    1304719139-4.JPG


    This funnel arrangement was in the tip, which is a guide for the pricker wire, so I'll keep it there

    1304719148-5.JPG

    1304719162-6.JPG

    1304719173-7.JPG


    Job done

    1304719194-9.JPG


    I said in my original post that the stove vapouriser has a larger jet orifice than the lantern version, so I prepared and silbrazed in a brass insert with the correct size of hole (0.23mm) using the techniques I developed and reported on in the fettling forum, here:

    Easy 'drilling' of 0.23mm holes and repairing a Monitor lipstick burner


    Here's the result

    1304719206-10.JPG


    I've a pricker wire to construct yet from a cut-down lantern one, but I'm getting nearer to that test firing!

    Trying the original short vapouriser pricker wire in the vapouriser tube I'd constructed, I found that it wouldn't engage with the jet orifice.

    The problem was a slight off-centredness to the jet I'd inadvertently imparted when brazing the insert and I'd not made a smooth enough 'lead-in' taper to the hole on the reverse side to guide the tip of the pricker wire into position.

    1304768015-1.JPG

    1304768025-2.JPG


    So I'd to make a better job of it

    1304768068-3.JPG



    Brazing cleaned up, vapouriser in position

    1304768106-6.JPG


    Checking the pricker functions properly ...

    1304768126-7.JPG 1304768141-8.JPG

    ... it did.


    Stove reassembled, ready for a fill of paraffin, using the distinctive Tilley funnel and with the Tilley priming jar and Tilley pre-heater torch to hand. The original vapouriser is now a useful spare.

    1304768163-9.JPG


    Flame shot

    1304768196-10.JPG


    On full power there's a tendency for the flames to lift away from the burner cap, but I've a feeling that's a characteristic of the stove rather than an issue with the vapouriser

    1304768227-11.JPG


    It certainly puts out the heat, which is pretty good going for a stove with a jet orifice the same (0.23mm) as that of a Primus 96's.

    Hi John congratulations on a remarkable fettle through out and it realy does put out the heat considering it has only a 0.23mm jet orifice. And all the pics of these stoves running at full power has the same flame lifting away from the burner so a perfect job you have done, John :clap: :clap: :clap:

    Thanks Brian.

    Some detailing next.

    Though it's my first Tilley stove, I've handled quite a few Tilley Lamps and still keep a few. Something I find perks up the overall appearance is to re-line the white paint in the engraved "Tilley Lamp" in the plastic control knob.

    On the stove's control knob what remained of the faded white paint lifted when it was in the ultrasonic cleaning bath with the other parts

    1304787169-1.JPG


    To re-line the paint I use a white paint marker pen intended for metal layout work

    1304787178-2.JPG


    At first the result's a mess, but a quick wipe with a solvent-dampened rag while the paint's still wet gives the intended effect

    1304787189-3.JPG 1304787206-4.JPG


    Later tonight when it's dark I'll round of this topic with some flame shots, including those remarkable 'flamelets' on the three vertical tubes below the burner that play on the vapouriser tube.

    Meanwhile, a couple of shots in the half-light

    1304805008-4.JPG


    Tilley put what they call the 'burner outer gauze' (that stuff glowing red in those flame shots) there for a reason. Their instructions for the Tilley stove recommend that the stove is working at optimum pressure when the tank pressure indicator ... that's this thing here ...

    1304805061-IMGP0885.JPG

    1304805049-6.JPG


    ... shows the centre level with the outer rim.

    Without the burner outer gauze and the tank pressure at the level recommended by Tilley, the flames lift off the burner and are extinguished.

    There's no doubt that without the gauze, the burner head shows a purer blue, but the tank pressure has to be reduced to make that possible

    1304805072-7.JPG

    1304805081-8.JPG

    1304805131-9.JPG

    1304805145-10.JPG


    I'd be quite happy to use the stove without the gauze, but the tank wouldn't be putting out maximum power (when that matters for specific cooking tasks) and I can understand that Tilley wouldn't want to market a stove with the potential to self-extinguish if the user pressurised the tank above a certain level.

    Indeed, Ian.

    It was your CCS shots of the burner in action without the windshield and seeing your stove burning contentedly at Newark last year that made me hanker after one.

    Took a birthday (and a sixtieth one at that) to justify the expense though!

    Hello All,

    I just wanted to say thank you to all of you who have posted information regarding the CS56 on this page. All this information greatly helped me in getting this CS56 back to working health. After some consultation with the folks at Fettle Box I had the proper replacement gaskets and was in business.

    I do have one significant question regarding this stove. In the pic you'll see that the stove is lit and working just fine. What I'd like to know is if I was dangerously close to killing myself.

    I did not have any kero at hand, but did have some White Gas or Coleman Fuel. The stove lit easily and burned well, but I have read elsewhere that it is very unsafe to use this fuel in Tilley pressure lamps. Is the same true of the stove?

    Again thank you for putting this information out there. I'm delighted to have a new stove to tinker with, but just don't want to blow myself up in the process.

    Take Care,

    John

    Glad the details were useful to you John

    Close to killing yourself? Probably not, but the stove is meant for paraffin and hasn't got the safety features that make Coleman stoves safe for burning Coleman fuel or white gas.

    You did right to change all the gaskets and that's ensured that your foray into using white gas was uneventful. If you hadn't it could have become a fireball and even if you got off unscathed your lovely Tilley would have suffered, cosmetically certainly but also probably de-soldering of the pump base joint and damage to the pressure indicator pip device (not user serviceable, so a replacement font would be needed).

    Not worth the trouble to use anything but kerosene as fuel, de-natured spirits as priming fluid.

    John

    Hi John,

    Thank you very much for a very nice post. I missed this one when it was first posted.

    I do have to say that the Tilley burner is a beautifully complicated little beast that I wish was more common a little more westward across the little puddle that sits between us!

    Thanks for sharing and the great work up!
