I'm subscribed to your channels and it's pretty much the only thing I watch on YT (besides some other channels you recommended like Jeremy Fielding).

Is there any tool / machinery design in your head that you've been unable to execute yet due to time / space / $$$ constraints?

+1 for your thoughts on patents.

Mostly time constraint. Have been thinking about building a gear cutting machine using a table saw or angle grinder as the cutter. Sort of a single purpose CNC machine.
