For the record, I (an engineer) test my own designs (both installation and performance) and sometimes fab them myself to identify pain points, something I encourage for all engineers.
Not as clever as a machinist when it comes to techniques for manufacturing, but I generally try to avoid the need for such techniques if I can. But sometimes it’s necessary.
It’s also how the people who have to actually make the things engineers design look at engineers.

This is also how engineers look at other engineers (damn engineers, they ruined engineering!)
It’s not the engineers fault that another engineer hasn’t yet invented a machine that can make what he designed.
