Bn2T Locomotive

Modeling Subjects Scratchbuilding
1

Ok here is the plan. I intend to use a paper model which I received today as a pattern and scratch build the little loco out of plastic, metal, or what ever else I can find. So I guess we will see how this works out. I have heard of ship modelers doing this so it ought to work for this.

Frame is coming together…

Still plenty to do.

Progress on the frame…

Added some more rivets…

Installed some of the brake parts.

Learning things as I go along like some holes don’t need to be drilled or damage will occur.

The second locomotive will be better.

Building the locomotive wheels.

This is the assembly jig.

The wheels are built up in layers. I have decided to go with a solid cast wheel instead of a spoke version.

On the frame.

I continued to work on the drive wheels for the “The Little Engine That Could”. Counter weights and driver offsets added.

I assembled most of the left side wheels. I still need to add the driver cam’s, but the loco is setting on all four drive wheels.

The wheels were pretty tough, but I’m sure there will be more challenges to come.

All the rivets are in and I have added part of the connecting rod assembly.

I’m still smoothing things out, but I think it will come around sooner or later.

The beginnings of a steam cylinder.

A mostly complete steam cylinder. Ready to move to the other side.

Ok that brings us up to date.

Thanks for looking! More to come.

Hello!

A nice idea, and the model is lookin’ good so far! If you need some help with the translation from polish please don’t hesitate to ask me. I’ve seen those loks built out of paper, too and they looked good. Of course those little details can look a little better done out of other materials. Good luck with your build and have a nice day

Super cool! I like trains, wish there were more train kits. I can’t wait to see more.

I want to scratch build a 1:24 Link trainer. I had enough pictures and published measurements of the prototype to do a set of drawings, but then I found a 1:24 paper model of the Link. That has sure eased the job. I put the paper model together, and am continuing to work on the drawings. I think paper models are a real boon to folks getting ready to scratch some subject!

Thank you Pawel

Yes not nearly enough.

Thanks

They sure seem to be good place to start anyway.

Thanks for stopping by.

Terry !

Now you see why I use the Paper Models as patterns !

As a train buff too , I laud your efforts here . The finished Locomotive ought be a stunner . You must keep at it ! Note; Did you know that for a time some engines and a lot of rolling stock ( Passenger cars ) rolled on compressed paper wheels ?

Yessir . A fellow was trying to develop a wheel that was lighter , but was just as strong . he found back in the thirties that if you compressed paper with Aliphatic resin to 5000 pounds per square inch , the resulting wheel with a steel tire could travel many rail miles before becoming to weak to use .

The ones used on engines were rare , But , that’s what yours look like . Good job . T.B. P.S. On some locos you can use thin wall P.V.C. Pipe for the basic tube for the boiler ! Also the holes you drilled could be filled with rivets made out of brass rod epoxied in place .The strength then wouldn’t be an issue .

Well I sure didn’t know about the paper wheels…wow!

I have been considering pipe for the boiler. Just been leaving that till later. The connecting rods are next.

Thanks!

Yeah Terry !

I found that tidbit in a book about the famous passenger rail cars of the early years .

Supposedly , one of the benefits was indeed a smoother ride !

More locomotive progress. Started on the connecting rods and springs.

Just a small update. Thanks for looking.

Before moving on some paint needed to be applied.

Hallo!

That engine started looking a lot better with some paint on - and it wasn’t lookin’ bad before, neither! In case of this project replacing paper with styrene seems to really make sense, although I’ve seen people building it out of paper, too, and with good results. Anyhow - good luck with your build and thanks for sharing, have a nice day
