HI All

The cassette design I have been using has proven to be a dead end design, but hay I had an idea but it did not work out in practice. Half the fun for me of working in 2mm is the problem solving aspect!

Part of the reason for the problems was one of the connectors / locators was 0.2mm too near to the right hand end of the cassette. This despite careful measurement and allowing for adjustment after assembly.

The cassette worked one way around, but it didn't work when turned round. I will now be using a more conventional design approach, using stationary clips both horizontally locate it and connect the power, this has the added advantages that it is cheaper to manufacture, the DCC power connections are automatically reversed when the cassette is turned around.

Hindsight is the only thing guaranteed to be 100% correct.
