Installed a Bark Box in my K-27 and there is good chuffing even with no load on the locomotive.

  • @paullubliner These are questions you should be asking Richard Jacobs. He makes the Bark Boxes one at a time by hand to fit a particular locomotive. Richie is a good guy so email or call him.

  • @trainav8r No I never heard of this before. Okay, silver soldered, so it's MAP gas instead of propane. What else is there to it?

    In 1 1/2" scale I've seen the petticoat pipe being left off to do this as well. See on you tube: "Chula Vista Live Steamers Fall '09 Meet" for my Hudson.

  • @paullubliner It's more than a tube and it is silver soldered to withstand the high heat of the smoke box. Are you confusing the Bark Box with a Suymmerlands Chuffer tube?

  • @trainav8r: A bit pricey for a short length of thin walled copper tube with nothing more than

    soft soldered ends, don't you think?

  • @paullubliner

    google bark box live steam to reach trainsales

    then ask Richard Jacobs if he has a bark box to fit your loco

  • @trainav8r: Thanks. I'd like to fit these to my Aster Gresley A3 and A4s. Any drawings available?

  • @paullubliner

    These will not work with a coal fired loco because the draft must be controlled, but they will work with gas or alcohol fired locomotives. Also see my video "K-27 Bark Box Under Load"

  • How significantly does this affect the draft? Is it only useable for gas fired engines?

  • @foreversteam

    The device is placed over a shortened blast tube. No screws. See also my video titled K-27 Barl Box Under Load for great sounds.

  • Wow!!! Must say that is impressive!!! It looks like a steel "resonance chamber" or drum attached to the chimney above the blast pipe amplifies the sound? I have heard of a chuff pipe which is directly screwed into the blast nozzle which goes directly up the chimney. Do you connect your blast pipe to this one/screw it into the blast pipe or is it seperate? Has anyone tried this bark box on a coal fired model? Thanks a million for posting! B.
