Project: minimum Gn15 layout with hand laid stub switch.

For discussion of the issues faced when building a model or layout - how to replicate wood, what glues to use, exactly how much weathering can a Gnat take, a good source of detailing accessories - you get the picture, I'm sure.

Project: minimum Gn15 layout with hand laid stub switch.

Postby Shozo.K » Wed Aug 29, 2007 9:58 am

Suddenly I wanted to make a stub switch but it is no use to lay only the switch alone. Hence the new project.
The plan in the 34cm x 24cm space intrigues both for fun to run and shunting puzzle. It is equipped with 90mm radius endless track and two short side lines. Each side line contains one trailer or two disconnect log cars.
Image
The switch fits to like this tight curve must be very hard to be laid by normal hand spike method then I decided to employ the solder laying technique.
Here the very helpful page to lay the turnout with solder and PC ties.

This is the result of my first trial of making flog parts.

Looks very promising Shozo. Looking forward to seeing how this project develops.

I'm watching this one with interest :) And I agree that is a prety tight curve.

solder laying track

Postby Shozo.K » Fri Aug 31, 2007 2:31 pm

After the PC ties were fixed on the plan drew on the cardboard with adhesive tape, I laid the rails on them with solder iron.
Image
I used a temporal track gauge made of thick cardboard but it didn’t work well. Especially when laying the track like this tight curve, normal standard is no use. You should use truck sets of several manufacturers directly to adjust the position of the various parts within the switch like wings, guards etc.. In this case the back gauge vary to the wheel sets cause the serious problem.
All parts were laid, I removed the track sections from the cardboard and cut out movable rail parts from the stub switch sections. Feeders were put on the bottom of the rail. Processed track sections were re-fixed on a plywood base with epoxy adhesive. The plywood is recycled one from the old furniture so that it's surface is covered with something like an wall paper.

Hi Shozo

Great track work, that is really using the space to the best advantage.

All my stock will have too long a wheel base but somthing like your plan running in and out of a factory would look fine :!: :!:

I like the idea of stub points where the stock is running at slow speeds

Movable rails were cut out from the rail stock. Brass wires for the shafts of hinge joints were put on the bottom of the rails. The shafts were hold with coil springs at the under side of the plywood base. The throwbars were made of plastic strip.
Image
Image
I employed a toggle switch for the switch stand. Of course it works as an electrical contact too.
Image
Image
The photo shows my awkward wiring far from the Michael's beautiful work but it does work anyway and sufficient!
All the gaps on the ties were cut by the motor tool with the cutting disk.
Test run with Bachman On30 porter and Tenshodo power trucks was executed successfully with a bit of effort to file the guard rails in the switches.

Very nice Shozo and great illustration too! Now I feel like I could attempt my own (notice the word attempt :D )

Thank you for your kind comment.
I really enjoyed to lay the truck and switchs.
Though I found it is difficult to run a loco pulling some trailer because of the S curve.
I attempt to build a loco and trailers fit to this layout.

Shozo thanks for your compliment re wiring, I do like your solution for the stub points, I shall have to make my next set the same way, The spring connection to the switch looks very clean and simple.

Great Idea to using the toggle switches. How effective are they at positively setting unsprung points :?:

Very nice work, I want to try as well, i do like those really small loops. My first one was small but not that small, another thing on the list!! I`m watching this thread, can`t wait to see were your going.

Thanks Michael, the advantage to fix the movable rail with spring is that anytime you can pull it up a little then remove the throw bar and paint the details freely.
I admire your beautiful work. Your Mercury loco greatly intrigued me. I’m wondering how I should bash it seeing the Percy and Tomas loco on my workbench.

Yes Simon, the toggle switch stand is very effective and reliable way to drive the unsprung points. Only notice to keep the moving distance made by the toggle switch lever longer than the movement of the throw bar.
You might find the connecting rod made of brass wire is bent to form the spring and small pegs on the sleepers outside of the movable rails that restrict the move of the throw bar. They are essential to make a thrust keeping the rails in right position. Of course normal turnout system with tong rail doesn’t need such tricks.

Thanks Scott, but this too sharp curve and small layout choose the actors. I’m now planning to make a special loco and rolling stocks for this layout. They will have very short length and original couplers I think.

We've just had a look at your website. There are some great ideas on there. Your trees are very lifelike.

It is obvious that you have a lot of FUN with your modelling. We have added your site to our list of favourites. :D

May your wheels never rust.

The progress in this week. :o
Image
With white glue, the thin plywood base was stuck onto the polystyrene foam board curved the wiring space and landform. Another plywood board was attached to the bottom of the polystyrene to make light and solid construction.
Sleepers cut out from styrene sheet were glued between the PC ties with proper interval. Simple wooden bridge was made of basswood. Side wall of the hollow is made of natural substance from the backyard ground. :o
I used paper clay to form the ground surface covering the gaps between the plywood and polystyrene. I prefer paper clay than plaster because it is more flexible to form a smooth and fine shape easily. :wink:
Finally the surface of the clay was covered with a soaked tissue paper to represent a course wrinkle of the ground.

Very nice Shozo, I have seen the paper clay at a local craft store but have been shy to use it, I`ll give it a try and now I have a 40% off coupon.
It`s funny but the material you used for your base looks like plaid grass.

thanks for showing us,

Scott

Hi Scott, materials for children is not only easy to handle but also, of course, absolutely safe! :wink:
The pattern of the base is a kind of Japanese traditional wall paper 'cause this board was recycled one from the old furniture :oops:

Hi Shozo

I like the way you are going about the layout. and I may use stub points on some part of my layout. They seem to be the answer to points when you have tight curves on a layout

Ralph

Usual Gn15 loco would not run on this small layout pulling the trailers due to the sharp S curve. Also the too short side line would not allow the shunting play.
Then, I decided to build an especially short length loco with 26mm wheel base power truck.
This is the first rough sketch of a special loco for my minimum Gn15 layout.
Image
And I am planning to build the minimum trailers on HO scale arch-bar trucks.
The loco and the trailers will be equipped with original couplers. That will resemble the LGB’s one to manage the tight S curve and to realize an auto coupling.
