Homebrew PCBs

Early on in the write up I experimented with holding the motor and PVC in a vise and using a file to "turn it down"

It worked but took ages and was messy.

So I decided to just tell people to borrow a lathe.

20 mins on a lathe or 2 hours with a file (and who knows how much you are damaging the motors sintered bearing) it's just not worth it.
