I’ll paint the underframes, and then the vinyls are all yours Jon! @PostModN66  :laughabovepost:

I sat down this morning intent on finishing the ends of the 323 but got completely sidetracked into fitting the couplings and test running.

Firstly, I realised I needed to shorten the chassis, because I had to shorten the body to fit the Electra vinyls.  I have done this before so it wasn't too scary.



The picture shows the chassis taken apart, the "slidey things" that hold the bogies in place have been moved one notch inboard, which is around 4mm each end.   By turning the slidey things around you can move it by 2mm, so you have quite fine adjustment of length.   I have chopped out the central 4mm of each drive shaft, then fitted a short length of plastikard tubing, drilled out to 1.5mm which is a good tight fit.

Here it is in situ on the chassis:



Getting these chassis back together is a fiddle; nearly always something drops out of alignment and you have to do it again.  There must be a clever way of doing it  ???

I then fitted Dummy Knuckle couplers to the power car, and realised I had to adjust the length of the coupler arm on the bogies of the trailers.  It is something of a miracle how this plastic brilliantly ignores Superglue; I ended up using Evo-Stick, and reinforcing with a wire staple.

A test run followed; I am quite pleased with the coupling distances.  I couldn't get @Cooper 's under frame detailing on for the power car; don't know what I'm doing wrong but I can't get it to fit  :worried:



Cheers Jon  :)

@PostModN66 have you tried it both ways? It is ‘handed’. I’m sure we can get fit again as it definitely fitted ok before.  ;)

Fitting all the bits to that type of split chassis with all the 'slidey bits' by using Tacky Wax to hold them in place on one side of the split chassis until the other side is in place - simples!

Today's task; making a representation of the 323 couplings.  I used a Dapol hook, cut down, and a complex structure of Plastikard with a bit of brass wire to represent the structure. and various bits of mechanism.  It took ages and was really fiddly....and I managed to take off a flake of the yellow paint @*&@£  >:(

It still looks a bit cartoonish, but quite honestly I can't think how to make it any better!



Really need to tidy those windscreen surrounds!

I have added the light clusters with tiny bits of plasticard and installed the LEDs for the headlights.   The unit will be uni-directional, headlights in the leading car and tail lights in the trailing one; no return workings permitted!



The wiring you can see through the windscreen is temporary to test the headlights.   I plan to put a voltage regulator circuit in each trailer car, akin to the way I have done numerous flashing tail lights in goods wagons.

Hopefully this build is reaching a conclusion; I will be so glad to get it off my to-do list... :confused1:

Tail lights next.

Cheers Jon  :)

So....made up two voltage regulator circuits (actually four, two prototypes rejected) and spent about a day (really) working out how to make the pickups.  Frankly in retrospect I would have just used button cells, but finally got the lights working  :confused1:



Net result....headlights too bright, tail lights too dim, so I need to change some resistors.  There is a lot of light spillage from the headlights which I hope can be cured with acrylic paint.

Cheers Jon  :)

Just scrolling through, catching up with this thread, I must say what an exceptional job your doing on that 323, she's looking superb.
I like to start each day the same, sit up and take a deep breath!
First objective for the day achieved, woohoo!!!

Thanks!  I really should get on and finish it. Other hobbies have predominated over summer!

Cheers Jon 😃

not just me then, I have far too many to-do jobs -

a 123, 2 x 304's and a 504 almost finished. Also a 506, 2 x 76's and a HST-E power car all primed and ready for painting. Then there's all the models that require chips fitting aswell as building my layout. I should've finished them by now but keep struggling with motivation, most probably because of how much I want to get done.

Vinyls on the 323 at last.

I have about a 40% success rate currently - more scrap vinyls than ones that went on OK.  They're tricky devils and you have to get it right first time, no wiggling time like waterslide transfers. 

Anyway I think it looks the part; although not perfect under close inspection.

I wanted to do a video with the lights on, but the chassis is playing up at the moment; maybe later

So, here is the promised video; Northern Rail Version, night-time shot.  Drunk people on their way home to Macclesfield or Congleton after a night in Manchester perhaps.



So nearly finished - just the couplings to glue in place and a touch of weathering.  I will be so glad to get this ticked off the "To Do" list!

Cheers Jon  :)

First vinyl application to the 304:



I'm getting a bit better at putting the vinyls on; need to be for the 304 as I have only one set!

This has worked out OK.  I had to chop 2.5mm out of the completed body and the roof, as the vinyls were shorter than the model, but it went easier than expected.

It is apparent that the 304 will need an interior.

Pausing for thought - and Sunday Lunch - now.

Cheers Jon  :)
