Porter Tender: Paintwork

With working couplers between loco and tender finished, I finally wanted to see some colour on the side walls. First, the stakes were painted with carmine red acrylic paint, as were the handrails. That turned out to be a bit tricky, but a second coating provided an acceptable surface.

After all handrails looked nice and the paint was dried, the red areas were masked with tape. You have to work carefully and pay attention to apply enough pressure at the edges of the tape, in order to avoid fresh paint to seep into the gaps of the wood’s grain.

Porter and Tender: Coupling

Of course, the electrical connection between loco and tender made it necesarry to add a coupling between the two before there could be any test runs. In order to stay close to the prototypical concepts and to make a long-lasting connection, I wanted to use threaded rods and square nuts. Unfortunately there was not enough room on the loco to use nbw on both ends, so I soldered a square nut onto a threaded rod with a diameter of 1,6mm. That way it looks like a genuine nbw from the outside, but can be screwed into the thick plastic frame.

Porter: Conversion to Battery Power

Now that the tender’s basic construction is finished, I wanted to achieve operational readiness. That required the porter loco to get converted from rail to battery power. The most important thing to keep in mind is to insulate the loco’s circuits from the rails in order to avoid “supplying” the rails with the battery’s current. Only then one is completely independent from other loco’s and can really enjoy the advantages of battery power.

Porter Tender: Stake Pockets

By finishing the tender’s frame (german version, translation pending) it’s about time to focus on the side walls. Quite an important part is to build the stake pockets, with the prototype they form the link between the side walls and the frame, with the models most of the time it’s just cosmetics. Since I’d like to build as many parts as possibly by myself and some prototypical pictures revealed that sometimes simple solutions prevail in the 1 : 1 scale, I chose the most primitive approach.

Porter Tender: Blueprints

After the basic requirements regarding the dimensions were cleared, an extensive online Image research took place. Apparently, opinions are divided whether a model Porter with a tender is a prototypical sight. Fortunately, I can avoid this topic altogether because I’m not going to model an explicit prototype. Instead, I’ll experiment with different themes and decide on a case-by-case basis whether and to what extend I’ll let the prototype reign supreme or just get some inspiration for my own creations.

New Construction Report: Porter on Battery Power

Since last September I’ve worked on a project, which I’d like to present now. It’s about a small Portor steam locomotive by LGB, which I want to switch over to battery that is accumulator power, controlled by R/C. At a later time I’d also like to adapt the looks.

This loco is supposed to make the starting point for my own garden railway, hopefully within this year. September and October were spent with some experiments to place all the necessary components within the locomotive. Alas, I had to take away too much of the lead ballast, so the loco wasn’t able to transmit its motive power to the rails.

Spring Suspension

After a long, long break I’ve found some time to work on my locomotive. In order to finally construct the drivers’ axle bearings, I need to be sure about what the springs’ suspension is going to look like.

Trailing Wheel Axle Bearing

Trailing Wheel Boom - Long Version — Trailing Wheel Boom – Long Version

Today I focused on the Axle Bearing of the Trailing Wheel. I’m currently wondering which would be the best length for its boom. Right now, I’ve got the choice between two versions: the originally drawn, long version and a new one, which is considerably shorter.

3D-Drawing Revision

A few weeks ago, I re-read my construction diary over at the railroad-line.com forums. Doing that I noticed that I failed to implement all of Thayer’s suggestions into my drawings. Most importantly the stack’s dimensions were too big while the boiler was too small in diametre.

Correcting the Frame

Why do I always notice such things afterwards? There I was, building the smoke saddle with trouble and care, brazing the bracket to the frame, attaching crossbeams… and then the bracket is misplaced and the whole saddle sits lopsided on the frame! -___-
