Close Coupling in an Instant


richbrummitt

I'd done quite a bit of thinking and head scratching how to make an instanter link for some time. The shape is not easy to make around a former. Indeed my first few attempts failed to make it off the formers. The process still makes some duds during the cutting and final shaping stage but on the whole I am managing to make some slightly better than triangular links most of the time.

 

This evening whilst clearing the workbench of assembled DC underframe etches and drilling headstocks to fit coupling hooks I pulled some of these triangular links and fitted them onto the closest appropriate wagon.

and coupled it up to the adjacent one on the 'work' plank.

On the left close coupled and on the right long coupled. I'll readily admit that they are really hard to get into the short position and couple there and there probably isn't much point but then why do we make these models? It's probably just because we can.

 

Please excuse the incredibly cruel close ups and poor lighting.

The mans mad, mad I tell you.  He'll be climbing mountains next  (because they're there!)

 

Well done Rich - I've been re-contermplating using them on the 'EM' side.  Think I'll give it a miss in 23mm!

Rich- I'm looking forward to the working screw couplings on the batch build of coaches! - BTW the wargon's arn't going anywhere  'cos the vac pipes are separated!

 

 

In all seriousness, these look really good. Well done.

They look brilliant Rich. Wonder how they (and you) will perform at an exhibition with Mr Knowitall breathing down your neck :-)

That's brilliant.  Must admit I'd never thought of a 'triangular' link.  I have 2 fiddle yards at either end of layout enabling me to run more stock than the original one.

 

Access to my more recent yard is 'banned' to certain stock as it won't go round the tighter curve.  This may just give me a way of having a common type of coupling, varied for how the stock is utilised.

Ssh. The men in white coats might hear you.

I've made some mock screw couplings for various NPCS. Have a look in my gallery at the Siphon builds. They have just two links. 

 

It's just as well the brakes are on. We don't want them rolling off on their own. I drop enough stuff on the floor as it is!

As long as I don't need to couple them we'll be fine :D Maybe I can invite Mr Knowitall to step up or ask politely that he STFU.

Kim and I have been known to hide at the back of the layout if he turns up:-)

 

I still think its bonkers but, I know, onions!!

Very nice Rich. You may not notice much when they are running in a train but they will show up quite clearly with the stock in sidings.

The type of arrangement, coupling wise are called 'insta' couplings

The GWR called them instanter. Perhaps insta is a shortened name from later in their life or that used by another company?

Rich,

 

As impressed as I am, I am beginning to think that you need some sort of help :-)  I must however admit that they look mighty fine though. 

 

Could you form the bottom of the link (the narrow bit) by pushing the wire into a slot then bending the top to shape around another former placed over the top of the slot? (the gap being made good with a solder joint - perhaps smoking a joint might help too) :-)

Do you have a white coat? If not you can join the club with my wife, mother, father, brother, assorted 4mm modelling friends, ....

Maybe. The jig would need a bit more thinking but it could work. My mind is working on moving sleepers at the moment and my bench is full of lever frame components but it's something that I can come back to.
