Thanks for the reply Steve. I have used litho plate on model aircraft in the past. If I remember, I don't think it can be soldered, I may be wrong. With modern print methods its difficult to get free now. In the photo of the garboard strakes on the armature you will see the fence preserver tins I am using.
Over the weekend I had been thinking maybe it would be easer to epoxy the plates together. Having almost finished the 2 bottom strakes I will continue soldering. Finding it easer with each plate, as I learn, little tricks. Cleaning the plates with a sanding drum (dermal), keep the plate flat on the bench. Otherwise the plate will cruel up and destroy the sand paper. Don't put to much solder on the iron, or I get lumps of solder as it runs down. I am now holding the plates in place with masking tape. That is working well.
The deck planking has been cut down to 3/32" thick, now have plenty at the right scale. Marking the nails & joints in pen I am very pleased.
