Pouring white metal is not difficult with a bit of knowledge and the right equipment. I have seen some fairly poor examples of work by professionals as well as DIYers. I have made several bearings for cars over the years and our steamer. My tips would be dont over heat the babbit material as some of the metals in the alloy can boil off and leave a less than designed bearing material if held too hot for too long and always preheat the parent parts. Most materials about 300C.
The best tip I learnt on the last bits I did having got the core stick in the previous job after sooting it up to make it non stick is to spray the core with a few coats of cheap red oxide primer. The paint burns off and the core comes out easily.
