I'm quite aware that you need other processes than casting. That's why my reference starter set includes a bridge mill, horizontal lathe, and hydraulic press. I've got reference sources on making a crucible from scratch, but they are not very expensive to buy. I used to do blacksmithing as part of my medieval re-enactment hobby. Reaching the melting point of steel isn't that hard, although aluminum is definitely easier. People have made a basic lathe starting from scrap aluminum melted in a furnace made from a 5 gallon steel bucket. But I expect most people won't have to go that primitive.Casting is all well and good (good enough for The Iron Bridge) but many applications require forming (forging, rolling) and/or machining. To melt cast iron or steel you obviously have to have a crucible which can withstand that heat. Aluminium alloys would be easier to deal with but you still need to know what particular alloy it is.
The equipment list for my prototype starter set runs about $30,000. Assuming a group of people pool their resources, that should be affordable. It includes things like a small industrial grade non-computerized lathe, which can be bought used for ~$3,000. The group of people either need to have, or learn, some basic skills among themselves - carpentry, welding, electrical wiring, etc. Some of the items for the starter workshop, like workbenches, would be self-built. Ideally, the starter-shop would be in operation *before* the unemployment problem becomes critical. A community workshop where people can get stuff done which they can't with their own tools has value on it's own. Then if the need arises, you can convert to self-expansion to meet the needs of people who are under- or un-employed,
