I am still working away on the details, a gent on the GOG forum pointed out that I had the front boiler slightly band too far from the smokebox so having checked photos and seen what he meant I moved it as far as I could. It’s now sat on the very rear edge of the smokebox/boiler joint rather than straddling them as I had it initially.

Next I turned what are probably the smallest part I have done to date. A challenge but satisfying.

This is the working drawing – Fusion in it’s wisdom seems to get a few of the sizes slightly under or over when creating drawings despite having defined dimensions in the sketches. So they are rounded to the full size i.e. 1.75mm for the overall diameter.

Finally with my obligatory 5 pence coin.
