Exactoscale wagon couplings - a problem

Postby Mike Garwood » Sun Sep 29, 2019 6:49 pm

Let me start by saying I love the look and simplicity of these couplings. I like operating with them, despite my deteriorating eyesight, and they'll be used on the fledgling Hengoed High Level. But why, oh why, do the links fall out of the hook- nearly every time - I put them away and then take them back out, half a dozen will have parted company with each other. Discounting the evil coupling pixies how do I stop this from happening? Someone with more brains than I have must have a solution without compromising the link chain.

And having returned from Scale4 can I say a big thank you to all concerned, especially those out in the cold of the car park. And to Terry a very big thank you for another inspirational show.

regards

Mike

Fill the gap in the top of the hook where the top chain link goes with a piece of wire or a minute dab of solder.

I used to close up the gap with a pair of pliers after inserting the top link. No falling out after that.
That would be an ecumenical matter.

I agree with our model making jockey. Some pliers do the job for me also.
Stick the coupling in a vice, drop in the chain, close the gap a shade, give it a wiggle and voila...

To get the links into the hook, you must have pushed them in, widening the gap at the top.

I broached the hole for the links out, to ensure the links would hang freely. This also made a burr across the top, ensuring the links would not fall out. The links were then threaded into the holes in the hook.

Sorry I reasoned that it would be wiser to thin one link and push it in to the gap...which is probably why they fall out, BUT, I'm only taking a nats wotsit off the link. I didn't want to compromise the shape and function of the hook.

Anyway, thank you for the responses, time to go and try....

The thinned bit should be half way up the long side of the link, then you have to try hard to get it to fall out.
But I just open the link and thread it in, then close the link. Can't do that in full size :)
