i found plans on a web site and based the scratch build on these.
The hull is plank on frame and you can see the stages on the attached photographs.
i used recycled materials.

Added detail to the hull, rubbing strips, etc.
Decided to show riveting above the water line using round headed brass pins. Used thick card as plating, glued on using pva glue over the whole hull.
Deck areas planked using lime planks, caulking was just pencil.

The clyde puffer used a chain drive for the rudder.
After a lot of research and head scratching i came up with servo driven slide arrangement with some pulleys and chain which funny enough looks like the real thing. Bench test proved it works ok.

Made from plywood to a push fit over the hull. Rivets fitted as per hull.
Funnel is a tooth paste tube.
Kitted out the wheel house and fitted nav and cabin lighting.

Hull now painted inside and out using car paint from halfords.
i find painting the most difficult thing to get right. There always seems to be something thats not right.

Had to do a bit of research for this. I happened to visit Beamish museum.
Low and behold there was a steam driven winch just lying on the ground.
This gave me some idea of what a steam driven winch looked like.
Made from plasti card, some gear wheels, brass wire, etc. Very happy with the result.
This is the second attempt the first one was too big, wrong scale.

This was carved from a solid block of lime wood.

Not much to say except used a thimble as a bucket.

Bucket is the top of a spray can and the tools carved from limewood.
These items were use to load,unload bulk materials like stone and coal.
Using the ship's Derrick made it self sufficient.

Decided to use a 6 volt lead acid battery.
Made up a chassis containing fuses,(Halfords) common busbar ( eletrical wholesalers, earth bar.) other stuff like switches etc from spares box.
The drive motor was left over from a previous project , wrongly ordered.
its geared so not sure it is up to the task, we will see.
