Hi all,

For my new layout (Minehead Station) i like to use magnets to uncouple the Dapol Easy-Shunt couplers.
And also they need to be operated manually.

Last week we (my little friends and i) made this contraption as a test.

Seen from below.

 

But let's start from the beginning.
What do we need:
Magnets
A miniature hinge
Screw eyes
Threaded rod M4
A hole saw
Nuts/washers M4
Knob to fit on 4mm axel
Tiny screws


First step, drill a hole with the hole saw, i used a 32mm (1 1/4" for the old fashioned  :-X)( :D).


The small disc we shall use again after some modification


Carefully remove one of the layers from the multiplex disc so when the magnets are attached it has the same thickness as the baseboard


While the crew is at work some people saw a nice photo opportunity (we don't care about Health and Safety :))


Moving back to the topside.
The hole has to be closed so in the future nothing will disappear in it (like ballast etc)
We used some very thin double sided tape and made a hole in it again.


Now a very thin piece of plastic is sticked on top.
Think it's strong enough, it can even carry a Land Rover with driver :D


Back to the other side again, let's unload all the materials.






The supervisor: "thought we would use very tiny screws, these things are huge!".


The hinge is attached to the wooden disc and it appears to be not that heavy at all.


The rod is bend in a vice and now we can assemble all the parts.


The nuts are there to prevent the rod from sliding (should have used some lock-nuts instead but didn't have them :hmmm:)


The uncoupler turned up and down



And again the uncoupler in action



Now we only have to do some testing and if all works fine i can continue (at last) with the building of the new layout.

André

That is very clever - and I like the way you use the 'props'.  :thankyousign:

I'm not sure I would use the system but love the presentation, a man after my own heart as the saying has it.
I look forward to more from you and your friends.

I don't think I would use this system it looks far too labour intensive especially if done at weekends Sat time and a half Sunday double time HaHaHa.

Nice tutorial, i found with magnets that they only uncouple at slow speeds so probably unnecessary, certainly on my layout to make a hole in the base and have a hinge.... Admire your efforts though!

Hi all,

Thanks for the tumbs ups, i am glad you liked it :beers:.

Forgot to mention some details of the used materials.
Bought it at Conrad in the Netherlands but the item numbers are the same at Conrad UK.

The magnets are 20x10x2mm (Conrad 542519)
The hinges                               (Conrad 227692)
The 4mm knob                        (Conrad 717647)

Have to do a few more tests but i think it works fine, so i can soon start laying the tracks at Minehead Station.
Want to install all the uncouplers before laying the tracks and switches.

Haha! best tutorial I've ever seen!  Amazing photography work, I will give this a try soon on my progressing layout.

Thank you for this!

Hi Brad,
 :thankyousign:

On this page you can see how i used them on my new layout (Minehead Terminus).
http://www.ngaugeforum.co.uk/SMFN/index.php?topic=25868.90

And here you can find a little video of the uncouler in action.

Hi Bob,

The advantages:
It's invisible
No unwanted uncoupling. When the magnet is down, one can drive forwards and backwards without uncoupling.
No derailments. When using a fixed magnet some small wagons tend to derail when the coupler is pulled down and the rear end lifts up.

Hi André,

I did enjoy your presentation using your little helpers, you obviously enjoyed setting the scenes up for the photographs and your efforts have produced a wonderful tutorial.

I wish you every success in your projects and hope you treat us to more superb tutorials.

Cheers John.

Hi John,

Many thanks,

It is indeed a fun way to spend time.
And it's also nice to combine two hobbies (photography and model trains).

Maybe more tutorials will follow if i stumble on something interesting.

André

André - get stumbling! The tutorial was easy to follow and the use of 'props' made it fun - keep it up.  :thumbsup: David.
