    A 'no-brainer' purchase. The ebay seller wouldn't post it, which kept bidding lukewarm, and he lived a couple of miles away from my place of work.

    1310836660-1.JPG


    The Shinabro didn't have its silent burner converter cap, but I found one from a Primus 100 fitted and worked fine

    1310836671-2.JPG


    Packing up ...

    1310836683-3.JPG


    ... packed

    1310836697-4.JPG


    For comparison, I took 'Rustbucket' (an Optimus 111) but fitted with Big Si's silent burner, which I'd been fixing, so Rustbucket became 111T-ish for a while

    1310837238-5.JPG

    Rustbucket

    Big Si's burner repair


    Most obvious differences first. The Shinabro's got a smaller tank; it has a roarer/silent convertible burner; it lacks the Optimus's control wheel controlled cleaning needle and has to have its jet cleaned 'manually' by a conventional pricker; it's BROWN and not a pleasant metallic green; the pot rests on the Shinabro are better than those on the Optimus - more on the benefit of that feature later; the case lid flips right back - again, more on the benefit of that feature later

    1310837254-7.JPG


    A shorter tank of smaller diameter on the Shinabro

    1310837286-9.JPG 1310837274-8.JPG 1310837304-10.JPG


    Burners - Optimus pictured first, then the Shinabro's

    1310837334-11.JPG 1310837387-12.JPG


    I stripped the Shinabro's burner for servicing, and had Big Si's burner in bits to do the repair on it, so compared parts.

    Control spindles - Shinabro's obviously lacking the teeth to fit a pricker rack

    1310838208-13.JPG


    The jet nipple on the Shinabro (left-hand one in each photo) has a flat reverse side to the jet top surface and not the conical contour of the Optimus one, which 'guides' the jet pricker in place. The Shinabro jet nipple also has a dimple around the jet orifice to make it a bit easier to find the hole with a hand-held pricker wire

    1310838220-14.JPG 1310838247-15.JPG


    Looking at the Shinabro burner, it appears to have been designed to accommodate an on-board pricker rack and I'm pretty sure my example could be modified to take one

    1310838276-16.JPG 1310838293-17.JPG


    Issues to be overcome to get that modification done are that the Optimus control spindle doesn't fit (the thread's different), and an Optimus jet doesn't fit (ditto) ...


    Continuing to service the Shinabro and with the non-return valve pip replaced - NRV at the end of the pump tube was conventionally 'Swedish', I turned my attention to the tank filler cap, equipped with a safety release valve

    1310838920-18.JPG


    As is often the case, the SRV 'pip' was rock-hard, so wouldn't have allowed the tank to get up to it's design pressure

    1310838940-19.JPG


    There's been a lot of discussion in these columns about the rights and wrongs of SRV servicing, some of which discussion I've indulged in myself

    Safe stove strategies


    Assuming I'd have little chance of obtaining a genuine Shinabro spare tank filler cap, servicing the one I had was the obvious way to go.

    Ah, a 'bottomless' thread - meaning, no positive stop for the valve insert ...

    1310838960-20.JPG


    TO BE CONTINUED

    Yes, that 'bottomless' thread. It meant that from first engaging the threads to as far as it would go there was quite a variation possible. Consequently, the SRV spring tension would vary a lot too ... so I opted for the valve insert being set flush with the tank cap rim

    In this post ...

    Discussion about Shinabro Royal stove



    Oh yes indeed, Dan, gloriously noisy it is (I like roarer burners to mean it)

    1310840196-24.JPG

    1310840207-25.JPG


    Simmers well though

    1310840221-26.JPG


    The Primus 100 converter cap worked really well ...

    1310840235-27.JPG

    1310840246-28.JPG


    ... but I found a conventional silent burner inner and outer cap worked fine too

    1310840268-29.JPG


    I said earlier that the Shinabro has better pot rests than the Optimus's and that having a case lid that folds right down is an advantage too.


    Demo

    Shinabro pot rests form a perfect rest for a wok, appropriately enough for a stove originating in the Orient. Of course, for a decent-sized wok at least, the wok-friendly pot rests would have little use if it weren't for the flip-down case lid to provide the clearance

    1310840288-30.JPG 1310840312-31.JPG


    Some might argue that the large-diameter base of a wok would result in an undue amount of reflected heat reaching the fuel tank. It's not proved to be the case in practice. The tank has an efficient heat deflector and the curved contour of the wok base creates plenty of clearance where it matters - which a large diameter flat-based pot wouldn't.


    Just to emphasise how the Shinabro scores over the Optimus for wok cookery, here's why

    1310840329-32.JPG 1310840345-33.JPG


    At first glance, pot rests that work so well as a firm platform for a wok fail for small-diameter pots

    1310840369-34.JPG


    Not a problem, the pot rests are simply switched around

    1310840388-35.JPG 1310840425-36.JPG 1310840457-37.JPG


    Excellent stove, especially if I can work out how to build in a pricker device ...

    Hi John brilliant post and documented photos as usual, the shinabro realy does look a great stove and built to a high quality, the only thing missing to the original 111 is they dont have a built in cleaning needle which is no big deal if the user dont mind or prefers to manualy clean the jet.
    I my self like the look of the pot rests better than the 111 but in your demo it is perfect for wok cooking which beaing a eastern/asian manufactured stove is proberbly designed for wok cooking or larger pots, but not very practacle for smaller pots which make the 111's pot rests more practacle,but still a very nice stove to have i have been looking out for one at a good price for a while once again John well done there on a great score and a brilliant post

    Thanks for the comments, Brian.

    I've not long ago polished off a chicken stir-fry, courtesy of the Shinabro, which worked great! It's powerful enough for the job, which as I posted here, is essential for a wok-burner

    Good wok burner stoves


    One thing I didn't mention in my original post, and that's the fact that the control wheel has a 'clean' function marked on it. This model most certainly isn't simply a stove with a missing pricker needle as you'll gather from the control spindle design. Presumably Shinabro just picked the control wheel out of the parts bin of another stove's set of parts - one with a pricker function.

    Hi John

    Great post, The shinabro is one of my favourite stoves, probably because it was my first silent pack away. The only think that stops me using the stove more is that it is very awkward to prick.

    I will have to look out for a primus 100 cap as my shinabro cap touches my wok when I use it.

    The inner cap on the shinabro has a down tube, like the one on a phoebus 625. I will post some photos today.

    Here is my shinabro. Things to note, different pump handle to the one above. Holes on the base of the tin are very uniform and I think they are factory done. I wonder if this stove once had rubber feet? I notice Johns stove above does not have the depressions which mine has around each hole. I have no reg handle (sob sob). Mine was brown when I got it.


    I really rate this stove, I once had a shinabro 170gr (8r clone), I now wish I tried the cleaning needle assembly from that in this stove.

    Interesting thing! :thumbup: Ok, an unashamed copy, but that's cool, looks like they did a good job of it. Looks like it goes like a good'un, too! 8) Can the pot supports be turned around for very small coffee makers? My back packing espresso maker is only about 3 inches wide. Wont fit over the stands of a 111.

    Nice stove!

    Hi, John,

    Another of your wonderfully illustrated "travelogs" of a journey through a stove. Fabulous. I read every word even though I don't own a Shinabro and indeed have never even seen one. Thanks for taking the time to put this together. Exceptionally clear photographs.

    John, excellent review and comparison. Looks like a mighty good stove that is comparable to many of the swedish types. I'm most impressed with the pot support design. Just swap them and they'll work just fine.

    Have a great day,
    sam

    Lovely stove, great photo's! Maybe a 'copy', but with well thought-out panrests, and both 'roarer' and 'silent' options in one stove. Hey, there's no problem with making something good already into something even better! 8) :content:
    Thanks for sharing,

    best regards,

    As Big Si says.

    Good colour match for the Shinabro, 400c is Plasti-kote, Rust Not, 793 Chestnut Brown, should anyone need to respray them.

    A quick trawl through South Korean stove examples in the Stove Ref Gallery shows that all of the Optimus 111-pattern stoves have those wok-friendly pot rests. Convertible burners are the norm too, but not all have case lids that fold flat to accommodate a larger wok

    It certainly does Mike

    Yes, the pot supports turn around so no problem with that espresso maker

    1310921092-Measurement.JPG



    As you say, Dan, the arrangement's quite different on mine, with this drainage grid in just one corner to cope with fuel/primer spillages or overflowing pots

    Hi John,

    The Shinabro 400C is an excellent stove, I bought mine from Bryan when he was selling his collection.

    It has a real "roar", in fact the "roar" is greater than any other stove I have.

    I like the design as it is so simple to change from roarer to silent.

    Great post, thanks.

    Cheers,

    Rob

    Excellent article, thanks. My 400c starts well but quickly looses pressure. I think it is the SRV pip. I can not find spares for sale so repaired the old one by gluing a disc of rubber to the old one. How did you make replacements? Any other suggestions on pressure loss? Thanks John

    John,

    Somehow, I missed seeing this post back when you first wrote it! That stove is flat-out wonderful!! I have to see about finding one of them for me-self! Many thanks for another wonderful report and photos, and for sharing this neat South Korean stove with us. I have grown to love the stoves made in So. Korea, and continue to seek them out, when I can! Take care, and God Bless!

    Every Good Wish,
    Mark
