Hmmm, the Hovercraft project is stalled, due to a problem with corrosion on the main battery pack lead - the copper strands are black, and I suspect it goes all the way back to the top of the pack
So, I've turned my attention to the reed switch on the 4-4-0 Centennial ....... the one wot I'm trying to put on the tender bogie.
Should be easy but .................. the bogie design is such that you can't double stack the magnets on the wheels, 'cos the flanges are too close to the plastic brake gear sub-frame.
So, I eventually remembered moving the sound trigger on my Buddy L from loco driver (when I put an 8-coupled Aristo brick in it) to the tender. The trigger was, I think, light sensitive, and sat in the middle of the axle.
I have found a Delrin gear, and a brass tube that just about fits the Bachmann axle and sleeves the gear, so I can mount this in the centre of the axle, and use more than one magnet
Wait for some glue to dry


and I'll post a pic.
After that, sharrafter work out how to permanently fix said reed switch in the right place
