OK so in spite of a load of work on at the moment, I've made a bit of progress on the traverser. In fact today it had it's first full testing of a run round and an engine swap.
There's some video of the engine swap at the youtube link following. Excuse the dodgy camera work - I was operating and filming at the same time, but you get the idea....https://youtu.be/uXBuQdJ3kC8
More to follow perhaps, once I find a competent cameraman!
