Kyle of Lochalsh

Finally for today I thought you might like to see some pics of the deck mods I have made to make it more like the Kyle turntable.

Thats it

Hi Toto
No I did not write the Arduino Sketch it came from WWW.DCCINTERFACE.COM Ian Jeffery had a hand in it. I just modified it to suit my requirements.
The interface board I am using came from the same place.

PART NINE

Now for the part of the code that relates to the number and positons of the deck.

First of all to define the home position.

So “FULL_TURN_STEPS” = 4800

If you divide that by 3

As in the line below you get 1600

// home location

#define entryStation FULL_TURN_STEPS / 3


I actually divided 4800 by 12 to give me 400 which is my home position.


This gives me the correct start position of the deck for my layout.

Now to get the reverse end of the deck into the same position you just need to

Take the position “entrystation” and add 4800 (FULL_TURN_STEPS) then divide by 2.


These are the lines in my version of the code


// this is home

gAddresses[0].address = 300;

gAddresses[0].stationFront = entryStation;

gAddresses[0].stationBack = entryStation + (FULL_TURN_STEPS / 2);


Now you can set up as many stations as you like . You will need to change

The “gaddresses” to the number of stations you need.



DCCAccessoryAddress;

DCCAccessoryAddress gAddresses[2];



So if you need two stations the code will look like this.

(My DCC packets start at 300 )



void ConfigureStations()

{

// this is home

gAddresses[0].address = 300;

gAddresses[0].stationFront = entryStation;

gAddresses[0].stationBack = entryStation + (FULL_TURN_STEPS / 2);



gAddresses[1].address = 301;

gAddresses[1].stationFront = (FULL_TURN_STEPS /8);// * 2);

gAddresses[1].stationBack = (FULL_TURN_STEPS / 8)+ (FULL_TURN_STEPS / 2);// * 2)

}

PART TEN

And here is a video of the turntable under test (sorry about the background noise it was the 3D printer doing its stuff) and the turntable noise is no longer there it just needed the central plastic bearing greasing.

I first reset the board then the deck moves to home then I press 301 close on the DCC controller to move to position 301 then I press 300 throw and the deck moves to300 reverse then I press 301 throw and the deck moves to 301 reverse then I press 300 close and the deck moves to 300.

PART ELEVEN
now for the base
I coated the base with glue then sprinkled on fine ballast grit.
as in the following

then I painted the grit with matt black to give the impression of ash

then I fitted the deck

Tested on the layout . I haven't got my Caledonian railway blue McIntosh 812 Class 0-6-0
so I loaded this loco for a picture.

Hi All
it has been suggested to me that others may like to build a turntable of their own to this design.
And to that end I am prepared to cut the 2 mounting plates and to post them of to
UK members at a price of £25 including post and packaging.
Note this is only for the 2 acrylic mounting plates.
If anyone is interested please PM me.

Hi Ian
thanks for your support.

Hi All
here are a few pictures of a direct drive version of the turntable If anyone is needing more details I will answer any questions you have. I do not have another Peco turntable to fit this to and as my geared version is installed and working on my layout I do not want to disturb it.

PART ELEVEN



So after all that I bet you thought that it was all finished.

Well I thought that a direct drive might be what some of you might want.

I actually made this direct drive first. But I thought that the geared system was smoother.

I then played about with the settings for the motor to get them as smooth.

So here it is.

Also required

3 off M3 x 50 mm countersunk screws for plate mount to turntable

4 off M3 x 10mm screws (motor mount)

3 off circuit board standoffs

 

I forgot the pin to connect the turntable to the motor connector is 5 mm x 20 mm glued into the turntable.
So that should finish this thread unless someone has any questions of if I can help in anyway.
Please get in touch either PM or through the thread.
