Kumar,

Looks very realistic. Excellent.

Thanks Michael and Dave. I'm going to use the rivets method on the next module.

With the two/three buses now fitted and powering all the track it was time to start fitting the turnout motors. I decided to use Circuitron Tortoise switch machines and purchased a set of six from Ebay.  I paid around $16 per motor.



If you've never used a Tortoise machine or powered up a handlaid turnout it can seem quite a hill to climb to figure out the wiring. Not only are you powering the motor to switch the turnout but you are also sending power to the frog of the turnout which has to switch poles depending on the direction the points have been set to.  It's been a couple of years since I last did this task so I went online to double check the power inputs.

The motors rely on a 12 volt system separate from the controller and therefore my first task was to get that rigged up using a small 12v DC adapter.  The layout now has three separate wiring systems:

  • A mains AC system for the lighting and the internal power adapters

  • A 15v AC system which then converts to a 12v DC system for the throttle

  • A 12v DC system for the turnout motors and miniature lighting around the model.



Once this new power source was installed I tackled each stage one at time and just mass produced each set of components.

This is very fiddly work but with the assistance of my 'third hand' I was able to cut, chop and solder to create the components very quickly.


Having all the pieces constructed before I started fitting the motors saved an immense amount of time and energy.


I built a second staging platform that sat on the first one. This allowed me to keep the turnout wires separate from the power wires. Not the best solution but I do have access to all the wires (kind of). If I ever rebuild the layout in the years to come I may reorganize this staging platform. The wires connect to the 12v DC adapter and then send power to the DPTD switches that power the switch machines.


Each motor requires five inputs as indicated and is fed from two separate DC systems.


I used a special adapter to fit the wires to the motor. This adapter then connects to a block and the various input and outputs required to make it work: frog, bus, and DPDT switch.


Anyhow each switch took about 30 mins to fit and 30 mins to power - so 1 hour per machine. I did the work over two weekends. It was tiring and stressful and not much fun. Nevertheless after fixing a few minor shorts and other small gotchas the whole system worked really well. My little locomotive was able to navigate the whole layout with ease.

I ended up with quite a tangle of wires. Nevertheless the underlying system is quite easy to understand and I labeled as much as possible. Shorts are quick to trace because I can isolate sections quite easily - all the wires have removable connectors. I don't know if there is an easier way to do it but anyhow it all seems to work really well. Only time will tell how robust the whole system is.






The whole video is on my blog - scroll down the page: http://thedepotonline.com/all/dc-wiring-part-3-turnout-motors/

Anyhow I am really glad this stage is over but I'm not quite ready to start modeling. I still have to build the exit points for the track to connect with the cassettes and also finish off the control panel (it needs a new diagram and re-positioning of the brackets).

I'll get to those in the next week or so and then I'll be ready to start with the structures.

Thanks all.

Very nice wiring job Kumard, I like your use of blocks to secure the wiring to. Our O-Scale switching layout should be approaching that phase in a week or so.

Back from a long break away from the hobby - first break in ten years. I got sideswiped by events beyond my control and had to take some time out to deal with the situation.

The Town's been sitting on its shelf for the last few months but this weeked I'm putting it back on the workbench to start building the structures.



The last time I posted the control panel was nearing completion. In fact I finished it and fitted it.

The diagram was printed on glossy photopaper in my color printer and I sandwiched it between the control panel backing and a sheet of plexiglass. I used a black and white version of the plan as a guide for the drill and held the whole structure tightly using clamps while I drilled the holes in my press drill.



The smaller holes drilled through nice and clean.


The larger ones did not come out so clean but the splintered edges are going to be covered by the washers around the switch.


The three layers that comprise the control panel will be held together using the switches.


The switches hold the three layers together. Switch E's thread got broken and I was unable to rethread it so this weekend I'll replace it before doing anything else.


I wanted a very lightweight control panel that I could easily remove for maintenance and I'm pleased with the result. The board can be pulled from its bracket very easily and quickly.



This marks the end of the wiring part of the project. Onto the structures and the fun part of the project!

Thanks all.

Just excellent trackwork. I always find layout wiring a little scary and yours is no exception but hay, it works and it looks like it will be easy to maintain so good job and congratulations.

It's only make-believe

Kumar,

Fine, careful work. The panel looks very neatly done with a clear diagram that will enhance operations.

Nice seeing you back at it.

Mike

Kumar, Nice to have you back posting again.
Really looking forward to your updates.
BTW Nice control panel, and very neat wiring, that we've come to expect from you.
