Dettingen GCR might have been layout

Like I said, no idea why the two photos are different sizes as came from same place. No idea how to change it.

Question for electric wizards.

the extra power wires were unscrewed from the far end of the power bogie. The light came from the inner ones which have the screws removed. With me so far?

the question is can I screw them to the same terminal or are input and output from the motor from different ends? The lump of metal seems to go around the whole of the side.

also fitted inner partitions. Seats to come once I can control all these stray motor wires. 

no partition at motor end because the motor goes too far into the cab and the passenger accommodation. No way around that  with this chassis though. 

Answers to my question gratefully received. Do remember I am an electrical dunce so keep the explanation simple please.

many thanks

Hi Richard,

 

I am not sure what you are on about with the electrics, but why don't you just put the pick up wires (the ones from the non powered bogie) back on the terminals you took them off? It should then go Brummm Brummm.

[richard i]

They are not really long enough now I have stretched the chassis and I am trying to save a job of soldering new wire/ finding new wire to solder on. I can experiment, but did not want to blow motor if wired up incorrectly.

[ChrisN]

Do you have a meter to see what connects to what?  I would hesitate to put the wires to the same terminal especially as I am not sure of the power to the motor and the light.  

[richard i]

Thanks Chris,

i did try both and it moved and lit up the light.  As long as your concern is power and not sparks or motor burn out then it seems to be a workable solution. 

Start of seats fitted to the partitions. Rest will fit on the floor.

Richard,

I would assume, and assumptions are always difficult and sometimes wrong, that the motor would draw more current than the light and so you might blow the light.

[Clive Mortimore]

Hi Richard

 

Was the light part of the original set up? If so don't wire it back in. Unless it was night time or in a tunnel the lights would not be on in the railcar. 

 

If you do want it wire it up in parallel with the motor. No harm should come to either. If you are over worried get you science teacher wife to put a meter on the components do some math with Ohms law and say there should be no problem.  

[Clive Mortimore]

If it was a Monday night and you had bought it down the club, Jim or I would have cleaned Keith's soldering iron while he looked for the solder. Reconnected every thing, realised it was running backwards, swapped over the wires and you would have gone home happy.

The light came from the motor directly previously so no harm should come from connecting to the other end. (.? )

you are correct club would be what I would have used. Rmweb has had to replace it. 

I am coming around to your view too about the light anyway, a gimmick which will highlight the big electric motor perturbing into the passenger space which better to avoid for illusion reasons. 

Thank you for all of the advice received . In need it. The boss is bio not physics so no help unless it has bones.

Hi Richard

 

Didn't Alessandro Giuseppe Antonio Anastasio Volta follow  Luigi Galvani in using a frogs leg to start with when experimenting with electricity but later realized he could do the same experiment with brine-soaked paper to show the flow of electricity? There you go bio and physics combined with history. 

[richard i]

Clive,

As ever, I concede to your greater wisdom in these matters. 

Richard

The paint is on. 

ignore the fuzzy edge to the white. It will be touched in later. 

Also unseen. The light has been cut out of the chassis. So more seats can be fitted. Though not as many as I would like because of the invasion of the cabin space by the motor and box on top of the other bogie. 

Also done gold lining and grab handles/ door handles. Pictures to follow when I have time to snap them.

Hi Richard

 

Do it go backwards and the other way?

[richard i]

Goes both ways but in end might have an old 6 wheeler behind it as it did sometimes in real life to increase capacity. That’s why one end has a goal post for the coach to hook on to. 

Lining and handles as promised.

[richard i]

The body painting is now all but finished. Unless the photo highlight an issue.

inside the brake and drive lever are painted. Roof tidied up.

 

i am still not happy with the exhaust will need to attack it with powders. I know some are not happy with the white roof.  However, photos show that it stayed more white than you might expect, maybe because it is not a steam engine. 

Richard

 

[richard i]

Look back a photo or two and you will see the bogies are the same dimensions. This would never do.

So made up side frames in a style of TW demonstrated in brass to make my 12at frames. With Clive’s words in my head too “ put them together drill through, simple really” 

 

they work........., I think, now need to build up the outside frames. 

Ignore the scrappy supports they will not be seen. 

Richard

[richard i]

Just plonked the body on. Definitely makes a difference lengthening the bogie.

now all the underframe gubins, fortunately there is not too much, some brake rods and a couple of Queen posts and rods. 

Richard 

[richard i]

It has taken a while to fit the outer parts of the bogie.

it now needs to have the queen posts fitted and some representation of the brake gear. I will do all of that in brass for strength. 

Richard 

[richard i]

My silence has been deafening. Things have been put on hold so the layout can be dismantled. 

It was given a Hoover and the yard went from grey to black .

All stock was boxed up for safety. New boxes had to be made. I now have 40 of the 4l boxes from staples holding built stock. Part of me feels that should be enough, but as I get my enjoyment from making things, I think I will keep going. 

 

There may be a little progress on the bench between now and September but I would not hold out for many updates. Life will be getting in the way. 

Richard 

[richard i]

This is big, well for me. I dislike glazing and I have done one end. Been too tired recently to face it. 

Also done the step widening so the bogies will have some rotation .

it is not much but all I can fit in at the moment. 

Richard

[richard i]

Yes. Windows are done. 

That feels better. Now for the under gubbins. 

I do need to channel  that red wire, and it’s friend I need to refit so they do not show. 

Richard

[richard i]

Exterior done! 

I have fitted all I can see underneath. I feel their would be a dynamo for electric lights or would this have run off the petrol engine directly? 

Next the seats to make and fit inside. 

Richard

[richard i]

It only allowed me a couple of photos per post so here is the construction of the brake rigging. Solder was the only way it was going to work out. Outside connected to the body, middle bits connected to the chassis.

I can't claim to have great knowledge of this. However two photos of these railcars I have seen in the book LNER Reflections by Silverlink appear to show that there was very little underneath between the bogies other than what you have included. No sign of battery boxes or dynamo. I hope that helps.
