So I have made a "mask" to go in the cab with the shape of the lights, and I think the effect is better, though certainly not perfect.   I'm not sure how I can improve it much with the technological base I have, so it's a question of is it worth doing, on 7 locos?



I am hoping for help with the Glue'n"Glazing tomorrow (@Cooper) so we'll see how it looks then.

Cheers Jon  :)

@PostModN66
Air damn secured to my 91 body (at the pointy end only)





The bogie moves freely. I wont be fitting a front coupling, but having seen the lights on the 90, I'm tempted. Id have to do red ones for the DVT as well.

Cheers
Kirky

So, @Cooper came round today, Did the Glue'n'Glazing and did a great job of detailing the buffer beam:   :thankyousign:



For the moment we have left the lights out; I just couldn't find a way of packing the components (voltage regulator, diode, capacitor and resistor) into a cab, and to split the components between the cabs seemed inelegant!

Can any electronic whizzes (@themadhippy, @Only Me, @njee20, @Bealman  or others - no offence if I have missed you out!) advise me, can you get some sort of micro-circuit to act as a voltage regulator that would easily fit in a cab end?   The circuit boards that come with more recent locos don't seem to need a big capacitor to drive the lights...

Cheers Jon  :)

You certainly put me in exalted company, but I'd defer to those others you've tagged as being far more knowledgable than me!

Massive improvement though with the glue and glaze, well done!

Ive done lights in the farish cl90 needs patience and fibre optics... and a dcc chip ;) you dont need a diode as leds are diodes in themselves... id use a 1k smd surface mount resistor and a tantalum capacitor again surface mount

Two more class 90s have had the @PostModN66 treatment, and Ive added the buffer beam gubbins. Freightliner one has a different shaped box and drawhook clearly visible. EWS one has rubbing plate and dropped buckeye. All ready for Manchester next weekend.

Brilliant Neal,

I really appreciate your eye for prototype fidelity; it adds a quality dimension to "Deansmoor" that I just wouldn't get to on my own.

Cheer Jon  :)
