Multi-Scale Bachmann Mogul

Postby Gnemo » Mon Nov 02, 2015 1:19 am

As noted in another thread, I am trying to convert a cheap Bachmann 2-6-0 into a Heywood-inspired Gn15' 0-6-0, with the option for a tender with a seat for a 1:12 scale engineer to represent a half-scale 7.5" gauge loco in 1:12 scale (to confuse matters further, I may also use it as a 1:18n1 loco with either a different tender or an interchanging seat).

Currently trying to decide whether to build the loco itself as a side tank 0-6-0T, with an extended back footplate for the 1:24 scale engineer, or as a non-tank loco with a tender (in which case I may want to leave off the side "deck" ahead of the spectacle plate, as it looks odd at a different height than the tender deck). Of course, running a side-tank loco with a tender in 1:12 scale will also look a bit odd. The side tank loco may also require a dedicated tailing car attached by a drawbar, as the overhang is likely to be more than the couplers can accommodate.

Decided to put side tanks on the loco, so will use a riding car rather than the tender.

Riding car superstructure slips onto a Gn15" 3x6 Heywood flatcar; the sides extend 1/16" below the seat supports and bracket the flatcar deck. I made the back wall a little lower than originally planned to allow better access to the storage area.

Sides and end are 1/16" basswood, seat support pieces are 1/8" basswood, and seat parts are 1/8" mahogany.

I am still undecided whether to cut the seat parts into individual slats. Engineer's front hips were carved away a bit further to let her sit lower.

One difficulty with these types of figures with bendable joints, is that they are sometimes out of proportion, with long legs and arms. Also being hard plastic, they won't 'sit' like a real person.
A big advantage of the low seat in wagon, is that centre of gravity is lowered. Not so much of a problem with lightweight figures, but even resin figures(and there are some very nice ones in 1/12th scale) are heavy, and can overbalance small gauged models. The same can happen in real miniature trains, and where as derailing a model is a nuisance, it is far more serious when real people are involved.
Making models that can be adapted for various scales is a good idea, not only saving money and time, but also showing how versatile these designs are as models.

Ms. Targaryan seems to have reasonably well-proportioned limbs, although her double-jointed knees will need some work to look right once the final pose is determined. Will test for stability first and rebuild with a lower seat if necessary (helps that the car has a cast metal underframe).

Some small progress on the side tanks and end platform. Alternate 1:24 and 1:12 engineers.

Progress stalled for a while due to wait for 1mm thick brass wire to arrive from China, distractions from some 1:10 and 1:6 scale projects, and trip to Oklahoma for the holidays.

Plan is to frame the portholes in the spectacle plate with wire rings installed on either side, sandwiching a piece of clear styrene glazing. 1st attempt, using 2mm brass wire on hand, came out too thick and clunky. The bottom 2 photos with the thicker wire demonstrate the technique, taking several turns around an X-acto #1 handle, snipping off rings, and flattening them. The ends are then soldered together, and the joint sanded down. Top photo shows a couple of the 1mm rings in place on the spectacle plate. Now need to figure out how to make nice even holes of the proper size.

Side tanks and the foot plate have been attached, and a couple of braces added for the foot plate.

Spectacle plate piece is only slid into place here, not glued. It slides into the same notches as the front wall of the On30" cab.
