This is just a test of the machining setup. I didn’t actually need a bulb this size. I made a larger version for a US1M boat that I did use and it is much larger. The larger piece of aluminum was pretty expensive, so I saved half the cost. Also, my machine is a CNC router, not a metal mill, so I saved half the wear and tear on my machine. I only made a few halves for myself, so I did not need anything more complex than this. I do plan on doing a more complex 2-part mold for IOM bulbs in the future.
Out of curiosity why didn't you make a 2 part mold?

@@ukktor do you need parts milled? I have a CNC mill. How do you attach the keel to the ballast and how do you attach the keel to the hull?
Which program did you use ?
Rhino3d for the design. vCarve from Vectric for the CAM.
