updating hornbys class 37

Carl,

 

That looks good and grubby. Top job! I'll be following the wiring section of this thread too.

Hi mark

 

 

Lighting!

 

 

Here are step by step pictures of how I do my lighting.

 

I did have a dud LED, it was fine after I replaced it.

Very neat job that carl. I did something similar on several Lima ones using Hornby 'Pacer' motors, I bet yours is a lot smoother though!

 

 

thanks

 

it is very smooth and i can not wait to get it in the body.

Hi all

 

I have been fitting the lighting today.

 

I have also removed all the copydex from the windows and fitted the rads

 

The Head code LEDs are 3mm warm white, but they are to bright, this will be sorted out when the box fronts go on.

 

Let me know what you think.

 

Carl

This is looking excellent. I know have an urge to go and do one myself.

 

Any chance of a video once your finished?

 

 

A video, no probs, i will upload one on my youtube and link it on here.

Hi Carl,

 

I did mean wiring.

 

I thought you were adding head and tails to both ends, my mistake. I wanted to see how to wire a pcb if both lights were added to both ends as all my reading says it's dificult to not have them all on all the time. I have a couple of brand new Bachmanns with DCC port, but no lighting and would love to know where to wire them in the PCB board. I thought I would have got an inclination from your thread, but I got my wires crossed (poor pun).

 

Looks a sweet loco all the same and well worth a read.

 

Best regards,

 

Mark

Hi all

 

 

Not far off finished now! About 90%

 

I finished off the wiring and fitted the fan, I have hit a problem with the fan, the motor is a 3.5v motor, I fitted it with a resistor so the 12v will not burn it out. Runs fine on its own, and with the lights, but will not run with the main motor, lights are fine. I will sort it!

 

 

I just have to fit the glass/ name plate/ window wipers, and fill the fuel tanks with lead shot. And do the front head code box fronts.

 

 

Thanks for looking

 

 

Carl

That's a huge transformation from a standard Hornby model (if you could call hornbys a model).

 

Well done and thanks very much for sharing your work with us.

 

Are your pictures been added via a third party site like photobucket or something? I ask because if you delete them at some point well be stuck for using your thread for reference.

 

All the best,

 

Mark

hi mark

 

the pictures are uploaded only to Rmweb and will stay on for as long as andy lets them.

Doing the flush glazing.

 

1st, trim out the inside of the windows, the windows taper in, so are smaller on the inside face, take care not to nick the outer edge.

 

2nd, cut out the flush glaze windows and leave a 1mm over hang edge on the square side windows and the same on the door glass, but cut the top over hang edge off as this snags on the inside of the roof. The cab side windows touch all the way round, so leave very little over hang edge.

 

3rd, do not add glue before you fit them, dry fit them and then using a knife, add super glue to the edge on the inside of the body, you only need a tiny amount.

 

that’s it done.

The front head code box fronts

 

 

 

Using the Hornby originals, sand the outer face flat, glue new 10thou card on to them, making them longer to fit the modified box sides, remove the locating lugs from there backs, drill a 3mm hole, glue on the clear 0.5thou card, glue on the light surround, then paint matt white vary lightly in the hole at the back. This now looks like off white glass from the right side, then I added some clear orange to the LEDs

 

 

 

After painting them just glue them on.

Finishing touches.

 

Fitting the nameplates.

 

Using a 3mm strip of masking tape, the same as I had for the painting stage, lightly lay this on the body side parallel and just under where the bottom edge of the nameplate will go, this will give you a guide to get the nameplate straight, I use super glue, 2 drops no more than 1mm.

 

I also fitted the window wipers.

 

Sorry for not taking step by step pictures of this but I did not see the need.

 

As it stands in the pictures in this post, all it needs are the head code box fronts weathering.

 

It runs great but the roof fan will only run on full power, I am looking in to integrating the rc hellis circuit board and battery, it will charge its self as it runs, its battery is 3.7v so will have to find a 6v resistor as it charges at 6v, doing this will allow the fan and the lights staying on after the loco stops, just the same as DCC locos but on DC track, if I get it to work I will post pictures.

 

Next post will be pictures and a video of it on the layout.

 

I hope this has been as informative as possible to all who do not know how to do this.

 

Thanks

 

Carl

 

ps, now i have to weather 37111 to match...lol

Hi Carl,

 

That's a cracking tractor, I'm particularly impressed with the marker lights which look just right when off and when on. RTR manufacturers could learn a lot from this!

 

A tip for the low-voltage fan motor: adding resistors to the power supply will mean the motor doesn't perform very well at certain track voltages (the same would apply if you used a resistor to drop 6V of the supply to your rechargeable battery) and you might need quite high-wattage resistors. An alternative solution would be a constant lighting circuit which can be bought from various suppliers (I think DCC supplies do one) but I expect you'd prefer to make your own - a suitable circuit is here: http://www.clag.org....ng-circuit.html .

 

Hope this helps.

 

Cheers,

 

Will
