Good enough. The basic principles remain the same regardless of
machine or spindle size.
First caveat: There's a minimum "cover charge" that applies to these
things - and while you can substitute time for money for a significant
part of the project, even a little machine like the one shown will
cost between $1K and $2K (in some mixture of $ and hours) before you
can do anything with it.
As you follow the developments, look for elements that you're
confident you can reasonably make/do/scrounge yourself - and recognize
those that you'll need to spend for.
Second caveat: Machine design _can_ be art. Machine fabrication
_cannot_ be art. Plan to spend at least as much time building fixtures
to produce the parts as you plan to spend making the parts themselves.
Every axis of motion will need a minimum of two (and more probably
three) parallel components - and for these "almost perfect" isn't good
Final caveat: The most recently-built machine is _never_ good enough.
