Crescent Limited 4-6-2

Post by JoeMalinchak »

I started on a new Crescent Limited 4-6-2 steam locomotive. I am making some small improvements to my design.The first one is that I added some weight to the tender. My Pennsylvania 4-6-2 is running well with out any weight as long as I have a car attached. I am think a little weight will help it when running alone!

I painted the Garolite tender frame black, and then added the pickup wires. The springs were then added, and I soldered the top of the springs to the wire to assure good contact.

This is my printed foam parts sheet that will make up the locomotive body and tender. I just have to cut them all by out by hand with a #11 knife blade!

Nice progress, I bought one of these in N-scale in Oct 2015.
Hopefully yours doesn't explode after 10 mins of running, but then again, mind had a faulty DCC chip in the tender.

Hi Siegfried,

The weight is 7.25mm long. I just cut one of the weights that comes with the 16-27 M adjustable chassis.

Hi Siegfried,

Sorry for the delay in posting this, the tender weighs 1.12 grams. I really haven't tested it yet, but it should be better than my original version.

I have finally returned to work on this project after taking a long break! I just completed my training with American Airlines on the E-190, and I am now back to a semi normal work schedule. Actually, I will be on reserve for the next month or two, so I will have even more time to do some modeling if they don't call me to fly!

This is my second prototype of the model, and I really enjoy experimenting with improvements to make my design better. On this model I used a more powerful 4mm motor out of a micro R/C drone. I also used M0.2 mod gears from shop.kkpmo.com instead of the M0.15 gears I used on my Pennsylvania 4-6-2. The M0.2 gears have larger teeth, giving a little more bite on the gear mesh. However, this lowered the gear ratio a bit. I used 12 teeth M0.2 gears to drive each steam wheel, and 13 teeth for all other gears. This gave me the same spacing as the M0.15 gears, so I can use the connecting rods from TGauge.com.

The model is running beautifully, and has lots more power than my PA 4-6-2!

I glue my wheels onto the axles using Gorilla glue. After gluing them on I place the model in this vise to keep them aligned while the glue dries. The glue sets up in 30-60 minutes. However, I was having a little problem with a few wheels sticking to the frame. I solved this issue by just running the motor for a few seconds every 10 minutes or so until the glue dries.

Hello Joe,
I let my gears with 0.6mm bore finished, so the wheels can be firmly pressed in without glue.
Kind regards
Uwe
