It is odd how the most trivial part of the model dredger engine, the base, seems to have occupied more consideration than any other parts of the entire boiler and engine.
Thankyou to those readers who have offered opinions about the base options. The most common design preferred, including SWMBO, was the brick base. I am still thinking about that one. Meanwhile, here is a photo of the engine sitting on the blocks of wood which I had cut yesterday. Not joined yet.
Another really hot day here, so just an hour or so was enough in the workshop. And this is what I made. Can you guess what it is for? It is made of redgum, a very hard dense Australian eucalypt.

Then 30mm

Then 49mm

Then bored to 60mm and split. 135mm long.
It will be used in the next workshop session.
