Fantastic build there popeye! The cast of the underframe looks very clean which is no easy job, I know I've tried it myself. I would be interested to know how you made the mould, was it in 2 parts or 3?
I think this will be the layout of all layouts when its finished....at long last you've thrown your hat in the ring (at least in terms of layouts) and I for one can't wait to see the results. In particular I'm looking forward to the bascule bridge model,
an iconic piece of engineering that's crying out to be modelled. In terms of marine modelling how about a chain bucket dredger for something a bit different.
