Before considering making one of these machines first lets find
if liquid photo resists are available in quantities suitable for
hobbyists.
If not the resists are available then we stop thinking about the
idea.
If they are readily available then we can start to consider the
coating methods your described.
The dry film resists are easier to apply, but still requires
laminating equipment. I'm almost finished building my photoresist
machine.
