    Thought I'd share a pattern and core box that I've been working on (slowly) over the past 6 weeks or so. It is a decorative dome/cover for the safety valves on a 7 1/4" gauge live steam locomotive. The original part was too small for the boiler (as it was built) so a slightly larger casting is needed. The complicated part was the fact that the boiler on this particular engine is angled so the curves are different on the "front" and "back" sides of the dome. This proved to be quite difficult to draw in fusion 360.

    This will be cast in yellow brass, hopefully in the next week or two.

    Looks like a very fine pattern. Lovely finish and curves.

    The core will be green sand?

    Nice work with all those curves.
    Tricky stuff.
