Better Pickups

So as I mentioned in the previous post I'd been having a few issues with the pickups on the Hudson-Hunslet. The main problem was that the material I was using to make the pickups was too thick which means it generated too much friction when pressed against the treads of the wheels. I did experiment with fitting it so that it brushed the backs of the wheels and while this was much better it was unbelievably difficult to setup.

I've now changed the material I'm using to 0.112mm phosphor bronze wire and this is both easy to fit and springy enough to give a good connection without producing excessive amounts of friction. You can see in the photo that the pickups now push gently against the tops of the wheels and this seems to work really well as the following video should demonstrate.

As I said in the previous post this isn't the final body for this loco as I'll need to check the revised etched parts so there will be more posts with another body at some point soonish.

  1. Can I hear it arcing? It's a pity you can't find some tiny carbon brushes. They would be perfect.
