    Hi All,

    I need to get motivated to start turning out some motive power.
    The PVLW is currently building a Brooks 0-6-0, Vulcan 0-4-0, Baldwin 2-8-0, and a Baldwin 2-6-0.
    The CNJ Brooks 0-6-0 is on this thread:https://www.trainboard.com/highball/index.php?threads/building-a-cnj-camelback-b-3a.130120/
    The CNE Baldwin 2-6-0 is on this thread:https://www.trainboard.com/highball/index.php?threads/building-a-baldwin-2-6-0.127751/
    Next I started on a Vulcan 0-4-0. I used Two castings from my dad's work with RLW of a 0-6-0 tank engine and cut it up to create the 0-4-0. I used a Marklin shell for the boiler/smokebox sticking out the front.
    The chassis is a shortened Marklin #8800 0-6-0 chassis.

    A few questions. How did you shorten the chassis? And are you changing motors then?

    Joe,
    Using a scaled image of the prototype and the motor size, I figured out the location of the motor to get the length of the chassis. I cut the chassis at a point were I still have the center channel, that runs down the center (gear channel) on each side. I cut a piece of aluminum to act as a key to fit in the channel, to tie the two pieces together, and epoxied the two ends together.
    I am using a 6x10 mm can motor.

    Here are some images of the prototype.

    As seen before in my other build threads, I use Illustrator to layout out proportions and motor location.
    The red lines are the chassis, gears, and drivers. The blue lines are the shell proportions. The orange lines are the motor and gearing.

    Hi
    A bevel gearbox doesn't work well. Why not make a gear chain made of step gears. This can be used to increase the reduction.

    Modellbau,
    I just wanted a 1:1 transfer of power at a 90 degree angle. I do not have a lot of experience with gears, so can you explain why this set up will not work well. I appreciate your input.

    Bevel gears bring a lot of side forces. That means friction. That's why you don't find them in watches, except on the winding, but it is operated manually. In addition, there are running noises. I would advise against it.
    The most important thing in a small locomotive is a flywheel. As big as possible. And the highest possible reduction to achieve a high motor rpm. Then something like this is also possible (skip to 1:25):

    Modellbau,

    Thank you for the input and the video. I know this was some what addressed in the other saddle tank thread, but this is still helpful.
    Can you recommend a source for gearing?

    I thought I might post some work that has been going on at the Pleasant Valley Locomotive Works.
    Amidst facility maintenance, physical injury, family health issues, and other necessary functions, the PVLW has been
    trying to build motive power through modification of existing Marklin chassis.

    In the past I roughed-in some essential dimensions in Illustrator to create a housing and modify a chassis.

    I am now embarking on a new approach. I am looking thru my research to match the stock of chassis I have to the prototypes I want to build.

    I am also trying to avoid changes to the gearing and drive wheels where possible.

    Two recent additions the the PVLW stable are a CNJ L6 Brooks 4-6-0 and a CNE/UTCo Baldwin 4-4-0.

    I have removed the original pole motors and replaced then with 6V can motors. I am creating housings using SLA. The pilot trucks will be remade.

    I will post drawings later.

    Impressive work and research thus far. Why WE are "gluttons for this punishment" when it comes to Z-scale is beyond me. Maybe it's because we enjoy pulling off the impossible. Not sure.

    Promised drawings...
    I am using MR Locomotive Encyclopedia for the underlays. I also use other sources such as the Locomotive Cyclopedia, early railroad periodicals, and builder plans when I can find them. I draw in Z scale and shrink the underlays to match driver diameter in that scale.

    Hello! I was looking at some of these saddle tank Engines a while back and printed this shell but never got a powered chassis built for it this was 3D printed!

    Walt,
    Good looking saddle tank! 0-4-0 or 0-6-0?
