Re: Motor Shorting

The Rizla paper trick seems to have worked and now it is running ok; no faltering, no arcing, no dead spots. For those interested, a couple of photos are attached before taking off all the bright brass and NS parts and dismantling for painting. Perhaps I should move this to another topic area but I ...

Re: Motor Shorting

PS - close up photos show just how much cleaning and tidying up is needed before it goes the pawnshop!

Re: Motor Shorting

Well, I can confidently report that it is not the brake shoes. However, I am getting intermittent shorts from the front bogie wheels touching the splashers (an elegant feature from Adams but impractical from a modelling point of view). As you can see, it is all very tight on the chassis and there ar...

Re: Motor Shorting

There are pros and cons to all pick-up methods. I have used split pick-ups on a tank engine before but found it a bit of a struggle. The thought of trying it on this kit, with representative working inside Stephenson valve gear - well, it would be a non-starter in my book. That said, you can't reall...

Re: Motor Shorting

I have used the longer drawbar from the kit and dog-legged it to pass under the front of the tender where a plastic pin engages with it. I have faced the rubbing plates on the loco drag beam with masking tape and, so far so good, it is all running fine. I will also put masking tape or plastic card o...

Re: Motor Shorting

Thank you for all your answers and suggestions and sorry for not replying sooner, but other commitments kept me away from the workbench until this morning. As requested, I have attached some photos of the arrangement. One terminal of the motor is connected to the loco chassis using a split pin throu...

Re: Motor Shorting

I will try that. It's all a bit strange, because if I stand the tender on the tracks on its own then it only shorts to one rail. Likewise the loco to the other rail. If I then test the tender connecting wire (with the tender removed) the other end of which is soldered to one of the motor connectors,...

Motor Shorting

I am building a Finney/Brassmasters LSWR T3 and have used a gearbox etch provided by Martin using High level 3-stage 54:1 gears with a Mashima 1624 round can motor. Pick-up is via the 'American' method with the loco picking up off one rail and the tender the other. This was working fine and I had th...

Re: The Socially-Distanced Challenge - Registration Thread

This is the first post I have ever put on this forum, hence the delay as I had problems logging in! Anyway, retirement at the end of March coincided with lockdown and one of the many projects came out of the cupboard (not of shame but set aside for when I had the time, certainly). The project is a L...
