Good Sand casting foundry ?

Sound advice. A small part, in a tiny quantity, I can't see it making financial sense. Buy steel stock to a known standard and start machining.

However, if you are determined, before doing anything with the pattern, when you find the foundry, talk to them about what they need first. Any issues with the as cast part if your mate isn't a known pattern maker, and guess who will get the blame for a poor result . . .

I would do a test casting in alloy first to "test" the pattern, then get the body filler out! easy and much cheaper to get an alloy casting done. but what..........

Firstly, does it need to be steel. If it does, because you need to weld something to it, only a few foundries in the country will take it on. Best actually going to them with a prototype pattern, they will then tell you if it will cast, or won't. Steel castings need to be very simple, with no sharp edges or thin sections, as steel flows like syrup, won't fill a complex pattern and will knock sharp corners off sand moulds. They can take a single pattern and repeat it however many times you need, but one pattern one box, so to save on boxes they often prefer to have a few copies of the pattern, stick several in one box and put in runners and risers to suit.

I believe malleable cast iron is more likely for a top yoke? but what do............
