I had almost 8 hours in the workshop today.  The base plate is progressing.

Milling the main bearing housing slots

Milling the main bearing housing slots.  Using a 14mm HSS end cutter.  Ended up blunt.  There must be some embedded casting sand still

Then I spent an hour or so painting the machined surfaces with marking blue, and marking reference points and edges.

Using a Knu vice to cramp the base plate to and angle plate, and a height gauge to mark the reference lines

Model Triple Expansion Marine Engine.

This is a finished version, very similar to  what I am building.

I do not like the colours, and it is running too fast.

Otherwise, it is a very nice model.
