Hi Dave,
I exchanged emails with David Clark a couple of months back and he's interested in an article on D604. I have drawings, but they are working ones I need to tidy up and dimension, a fair chunk of text..
I don't plan to do an absolute beginner's article, I will aim it at folks with basic turning and milling skills. This means not many photos of setups, mostly of components and stages in the build.
I spent about £100, but that was with a donated motor and batteries (from a fire alarm) and the luck of a big sheet of ~1mm brass in stock for the platework.
problem is I got distracted from finishing the windows on Sunday, and ended up drawing out a general arrangement for D707 and 0-6-0 in 7 1/4" gauge. My working name is "The Beast"
