It’s hard to start a business without any connections.
Connections with people – because no industrial company will have time to talk with a random guy about producing 60 round elements, 3mm diameter each. (later it turned out anyway that there are technological obstacles anyway 🙁 )
Knowledge of technical solutions – if you spent your life on studying art, how are you supposed to know what to use to cut specific metals and what are the possible solutions.
However, if you read, talk and aim for finding ways, they will appear when the right time comes.
