I just took down our brass/aluminum foundry and moved it to the new shop location.
To make something like this happen you need to raise 200k from people not intrested in profit...then it will take about a year to make molds and coreboxes..make some tests...correct whats wrong...and make a test series.
After that you need about a year of roadtesting to see what kind of built in tension and other issues you got to adress.
In year number 3 you can start selling and the people investing the money can then buy a block at reduced price.
Its not undoable just a very hard task to get the financial part to work out.
If you could sell one a week...im not sure you could sell one a month...no one wants to set up machining equipment for doing one at a time..
