  • Reppingen EKB - thread in English

    Hallo,

    A few things more to mention...

    The gas filler adapter from Reppingen was filled with brass dust and chippings.
    I didn't discover it before I attached it to the filler valve, thus the valve
    and tank was filled with brass dust.

    I scrapped that valve anyway and instead replaced the small valve
    with a self venting Ronson valve as used by Accucraft.
    It has the same M5 x 0,5 threads.
    (Note that the Roundhouse gas valve is M4,5 x 0,5.)
    I can then use the same type of gas filler adapter as I use on my other locos.

    Reppingen valve right. Accucraft valve left.


    To be able to close the lid on the left water tank I chopped off the bush on the gas tank.
    There is still more than enough of the threads left to fit the valve.

    Best regards,
    Thomas

    Hello EKB-fans,

    Then my railway has got a new loco in working condition.
    After a long and sometimes frustrating building process
    the end result seems to turn out very well.

    After adding the cab I got some nasty sounds while driving.
    It was caused by the brackets on the water tanks being too deep and
    getting in conflict with the bolt heads on the expansion links on both sides.
    Some more milling and filing fixed it.

    The switch from CTI-Modellbau works very well.

    A few updates...

    The steam regulator was shipped to Reppingen for a fix
    and now works very well.

    The safety valve was a lot easier to adjust when hot.

    I have doubled the size of the hole in the footplate for
    the whistle steam.

    The servo used for lights turned out to be too cheap.
    After a while it got very hot and the lights got dim.
    Instead of using a more expensive servo,
    I will try the Lokbeleuchtung mit RC schalten. and
    have ordered a switch from CTI-Modellbau.

    Zitat von Thomas

    Wie weit ist den Grävesberg weg von Gävle?
    Die TGOJ M73 würde mich für Details schon sehr interessieren.

    Hallo Thomas,

    Grävesberg? Ich denke du Grängesberg meinst? :GR
    Ich kenne der Ort nicht, so dann muß ich Google Maps benutze. :wink:
    Bitte schreiben mir ein pm in Englisch,
    und ich kann vielleicht weiter helfen.

    I have done the first few test steam-ups and have some issues.

    The steam valve doesn't close properly.
    It leaks steam when supposed to be shut.
    I have verified this by detaching the steam pipe from the valve.
    I have contacted Reppingen, but not got any reply.

    According to Reppingen the safety valve should open at 4 bar
    and close 1 bar below, ie at 3 bar.
    My safety valve opens at 5 bar and close at 3,4 bar.
    How can it be adjusted? Is it like the Roundhouse valve?
    I have tried to use a plier in the holes on top, but it seems stuck.

    Else, it seems like this is a very powerful and easy rolling engine.
    It will probably require a heavy load to pull.
    Though, it ran quite well at only 0,3 bar on air, but I'm not happy
    with the timing on steam, so I think I must do a second round of fine tuning.

    Hi EKB-fans,

    Very slow progress, and I only have my self to blame. :pff:
    I have now mounted the lamps and done the wiring.
    I think it is a good idea to do it before mounting the footplate to the frame.
    The lights are controlled by a small and inexpensive servo which is
    controlled by a tree-way switch on the RC transmitter.
    The servo motor is removed and the potentiometer is replaced by two resistors.
    By using the trim for the center point I get 'on forward' - off - 'on backward' on the switch.

    Fröhliche Ostern,
    Thomas

    Hello again,

    Thanks for the info. I found myself sounding a bit grumpy here, but it is not really the case. More a matter of frustration. :roll:

    Anyway, I have got an e-mail from Ralph Reppingen saying he is getting help translating the user manual into English. :TOP Though, I don't know whether this indicates that there exist a user manual in German. (?)

    Note that my criticism of the building instructions is not related to language issues. In case any other read this and wonder... the building instructions are only available in German. I have had no problems with that. I have also got the building instructions as a PDF file which makes it easy to copy and paste into Google translate if needed. Though, Google sometimes makes some funny and weird translations.

    For "Deutsch - Norwegisches Wörterbuch" I can recommend Heinzelnisse.

    Regards,
    Thomas

    Hi all,

    Thanks for your answers. As I said, disappointments are all about expectations, and mine where certainly wrong. Sounds like this is what to expect from a Regner kit as well?

    Yes, the Brits seem to be a bit paranoid regarding boiler testing and certificates. Then I assume that non of the German vendors like Regner, Herrmann and Reppingen deliver their locos with such. (?) The reason for asking was this image on the Reppingen website showing an EKB with what seems to be a serial number on the boiler.
    [Blockierte Grafik: http://www.reppingen.de/images/Lokomotiven/EKB19c/EKB19c_02_gr.jpg]

    I think I manage very well without a user manual. I just expected there to be one. I'm only looking for specific info about the EKB. Things like the working pressure can vary between models and vendors. As Reppingen also sells RTR locos it is strange not to provide any user manual. Though, I find it even more strange (and a bit annoying) that Reppingen does not answer my questions about it. Investing some time in documentation will usually pay off in less support, but of cause it is a trade-off. Though, I guess Reppingen would save both time and extra shipping costs by at least making a check list for him self. :wink:

    In January I started on a Roundhouse chassis with Riverdale boiler, and it is a totally different world. Nice and detailed building instructions and complete check list for all parts. The Roundhouse building instructions can be downloaded from their website and can actually be useful reading when building any live steam loco.

    Kind regards,
    Thomas
