Busy morning with Jo's mouse sander making the larger lift-out bridge easier to fit in place.
When I first built the 2 bridges it was during the summer, during the winter the steel hull shrinks and they were more that a tight fit.
I had cured the smaller bridge before my back went last year.
Now the larger one has room to spare which I have a plan to cure, which I have successfully used on the smaller bridge and works well.
Once I finished sanding I glued the new section of sleepers in place with Evo-Stik, fitted the rails to align the sleepers correctly.
