Alan,
You have made a wonderful model of ALASKA, well done.
The noise on the Vid at 1.25 mins, is that the pump motor that is clattering away, if so is there any way to cut down the noise.
I look forward to your first trials in the canal, remember that with such a big prop you will not use so much steam, on the bench running free the steam is not working and is just rushing thro' the engine.
The finish on your model is superbe.
George.
