    Default Nn3 Climax A kit coming

    Well, as of last night, my 'proof of concept' idea on getting a Rokuhan critter mechanism to adapt to my existing Climax A kits actually appears to be successful. The prototype just test-ran under its own power, with a gearhead motor, on the test track, so I'll start to announce it as progress made, photos to follow. This is the same general kit I've had in production for ten years now with the following features:

    18-ton horizontal boiler version: Cast metal boiler; older wood-frame version, round water tank. This will have a 25:1 gearhead reduction in it as standard design instead of the rocket motor you get with the Rokuhan chassis. This will creep like a Climax A should, and also have an open-format cab for realism.

    13-ton vertical boiler version: Pretty much same deal but I haven't built one yet so stand by.

    If you look at Climax A production records there were probably more narrow gauge ones than standard, so this is a pretty logical fit. Because the shorty log cars are available from Showcase Miniatures and done in pewter (same ones that WBV used to print on Shapeways in FUD) you can do a legitimate Nn3 eastern logging operation on a very minimalist basis. I'm dipping my own toe in on Nn3 with this now.

    If you've been looking for a reason to get one of those chassis, this is it. Rokuhan SA001-1, I got mine from Plaza Japan, but I know there are others. This is as much fun as the Kato 11-105's has been, just a smaller version of the same idea. I've been incredibly fortunate that Kato has kept running those critter chassis for about 12 years now, I have no idea if these Z Rohukans are a flash in the pan or a staple product, but they are a game changer for sure.

    Looking forward to seeing these results. I had held off on your Climax because i wanted it for Nn3. In 2009 (can't believe that time has slipped by...) I exchanged emails with you regarding a possible narrow gauge Climax.

    As my tribute to Halloween..... "ITS ALIVE!!! ITS ALIVE!!!" The FrankenClimax Nn3 version passes its running tests:



    I've still got to write instructions. Just to prove that I'm not messing with you, the standard gauge version on N track is in the back, this is setting on Z track and the log car behind it is a Showcase Miniatures Nn3 log car with MT trucks under it.

    If you want to prepare, you'll need the following:

    Kato 11-105,6 or 7 chassis
    Rohokan Z shorty chassis (pretty much just for the trucks)
    Solarbotics GM15A 25:1 micro gearhead

    The only real change on my kit is a new frame designed to work all that stuff together.

    Kato has been putting out their chassis now for almost 15 years, but I have no idea if this Rohukan is a one-shot or not, so I'd get one if I were you. The Solarbotics motor started out as the GM15 with a pulley on it, now it has a D-shaft and is the GM15A, but other than that it's identical to what I've been using for years.

    This does it, I'm going to put a Nn3 logging line in. Back in the day, I bought a Micro Trains Nn3 C&S 2-6-0 when they came out and didn't think it would do very well for a logging loco, but what you have here, Randy, is justification to put the logging line in.

    Well, it works. The Nn3 version of my Climax 18-ton kit. Got to set up some test track tonight and run it around, with the gearhead drive.





    And just to prove it really is the Rohukan Z shorty trucks under there....

    Kits are shipping now. I send out the instructions first before I'll accept an order because make no mistake, this is a challenging kit. But I'm satisfied that's it's both repeatable and worth the effort to get a tiny gearhead-driven Nn3 Climax out there.
