Hi there, at university we made 70cm long RC sailing yachts for a project. The university provided the bulb keel and once the project was over the keel bulb was returned. Now I’m looking for how I can get a new keel bulb made. The original was brass, about 250mm long and mass of 1kg. I’ve made a 3D model of keel bulb so does anyone know where I can get one custom made? Thanks
