Re: Smoking QTT/T Gauge steam locomotive

Post by MIHS85 »

Interesting discussion and hats off to all of those here working on coming up with a working T-Gauge steam loco.

A couple of thoughts:

1) Uwe is probably right in saying that a fully detailed, reliable and commercially viable T gauge steam loco might be very expensive. Most special Z-scale loco models from European small-volume manufacturers go for somewhere in between $450-650, some for up to $1000. And whilst quite small compared to H0 an N, I would assume that the Z-scale market still is substantially larger than the one for T-gauge. If someone asked me how much I’d be willing spend on a T-gauge steam loco, I’d say that $200 would be my limit. My reasons for that, apart from a finite budget, are twofold: all the other current limitations of T-gauge (points etc.) and some lingering personal doubts about the long term viability and availability of T-gauge which presently keep me from investing too heavily into this scale.

2) The experts here will correct me if wrong, but I would imagine that fitting a fully functional valve gear onto a T-gauge loco might be one of the biggest complications and potential source of both cost and trouble. If so, I’d be perfectly happy with a compromise of getting a steam loco chassis with functioning big wheels, a 3D printed body shell and etched static gear valve imitations for in front of the wheels. Fully working gear valves could then be left as an option for the more advanced tinkerer. A bit like the kit solution mentioned by Jesse.

Just my five cents,

Chris

I also think that it makes sense first to offer a steam locomotive as a series locomotive like Joe's steam locomotive. So kept simple, also regarding the valve gear. A complete valve gear, as I build it on my locomotives, is a lot of work, I'm experiencing that again while building the Flying Scotsman! MÄRKLIN has also produced many, many years steam locomotives in Z with this simple valve gear like Joe's locomotive. With such a locomotive a price around the 300 euro is at most feasible. That could fed the market. Above all, it would be important that such a steam locomotive drives well, so has a much better transmission reduction than the trains offered by KK Eishindo today. My locomotives have 24: 1, this is a reduction that is more than three times higher than the ultra-high-speed-trains of KK Eishindo.

Not good! The tender is driving too slowly.

An improved wire lets hope that in fact there will soon be the first smoking steam locomotive in T Gauge!

The project smoking QTT steam
locomotive has failed!
If I take a wire with little resistor (5 Ohm), the generator smokes, but the locomotive does not drive, because the motors get hardly any power. If I take a wire with greater resistor (15 Ohm), the locomotive drives, but the generator smokes only slightly. And the little smoke does not penetrate through the very small holes in the chimney.

The Flying Scotsman is now finished!
Overall, the locomotive consists of 232 single parts, of which 182 made by myself (210 hours of work).
Steam Wheels, Magnet Rings, Spokes Slices and Rivets by TGauge.com (24 single parts)
Back Run Wheels & Axes and Tender Wheels & Axes by KK Eishindo (14 single parts)
Gears by Mikroantriebe.de (2 worms and 8 gears)
Motors Made in China (2 motors)
All other parts (also the Valve Gear, 42 single parts hand made!) made by myself (182 single parts)

The locomotive is NOT for sale!
I will donate this locomotive together with the MALLARD one day to the National Railway Museum in York.

..... Not really sure what to say more than its very very impressive. You are for sure pushing the limit. Great craftsmanship.

Do you mind if one of use posts a link on the Facebook Forum to the YouTube video?

Thanks for the compliments!
What I upload to the internet I generally release for general use. You can do anything you want with it. But wait, the right video will follow!

Great work on your Flying Scotsman!

Please tell us more about your smoke system. Is it your design? I am sure the problems with it can be worked out, or you could make a new design for it.

Joe.

The photo shows the first smoke generator with 0.2mm wire, 5
Ohms. This smoked very strong, but the locomotive did not drive.

https://youtu.be/7wKmhO6dFqc

The video shows the second generator with 0.1 mm wire, 15 Ohms. As you can see, he smokes very weakly, but the locomotive drives.
In T Gauge a smoke generator will work only digitally, if you have a decoder that is small enough and delivers 0.5A for the smoke generator.

As smoke substance, I use the viscous UHU Superglue SUPER.
It burns to white powder, which can be easily removed with a brush.

Thanks for posting pictures, and the video of your smoke generator. I agree that a decoder should work to power the smoke unit.

Hi Uwe,

Can you share some of your techniques on how you are building your beautiful locomotive bodies.
What type, and thickness of material are you using?
I know you mentioned that you are using a small scissors to cut out parts. How are you getting smooth edges on the body parts?
How are you assembling the parts, glue or solder?
Are you hand painting them?

Thanks, Joe.

Hello Joe,

sorry that I'm answering so late, I have not get any info mail about your post.
The bodies of the 18 201, the S1 and the Flying Scotsman are made with 0.1mm copper sheet metal. The body of the Mallard I milled complete from a piece of ebony wood free hand with a PROXXON. The 18 201 is partially hand painted, partly covered with decals, the MALLARD and the S1 are completely hand painted with a brush (I take Email Color from HUMBROL, made in Great Britain, this is the very best color, more better than the colors from REVELL!! They are thin liquid and so they are going very well, so that it becomes with a brush nearly like air brush!), the FlyingScotsman, however, is completely covered with decals.
I solder as the first choice. I glue only if it can not be soldered, which is usually the case with the small locomotives. I often make electrical connections with liquid silver, for example, the lamps are so contacted, but also the motors.
I use a vernier caliper to mark the metal sheets and then cut them out with the small scissor. So I get exact parts that I do not have to rework. To bend the boiler plates, I take a tube with 4mm diameter to help. The cabs of the Flying Scotsman and of the S1 are made with many small single parts, so that the windows are broken. WARNING, it was a terrible fumble to glue the parts together! (-: But I also have already cut windows with a scalpel, such as my last locomotive the Köf.
Otherwise I do a lot with acrylic glass. For example, the connectors of the frame parts from the chassis or the cylinders. The buffers I make out of pins. I put this in the PROXXON and turn it freehand off with a diamond grinder. The valve gear I make with 0,1 steel plate from old mobil phones. I first drill the holes and then cut the rods freehand with the PROXXON. But I think, nobody does that like me! That's because no pliers help because it does not hold the parts tight enough. I hold the tiny parts in my fingers (I have hands that are smaller than most women! (-: ).
I hope I have expressed that in English reasonably understandable, it is not easy in a foreign language to describe exactly what and how to do something. Otherwise, ask if you want to know exactly.
In my videos on YouTube is always the building of the locomotives in some photos to see. At the Flying Scotsman also here in the forum. There is also a photo of the tools I use.

Kind regards
Uwe
