Upgrades for my Harbor Freight mini mill
Guy Marsden
@guymarsdenmakesstuffAbout
Since February 2022 I have started focusing on things I make with my mini lathe and mini mill and the improvements I've been making to those machines. Additionally since 2019, I have been making a series of collaborative art clocks with my friend Dave Bruckenstein and documenting the process of making them. My back catalog includes documentation of my electronic kinetic artworks, how I built my wood canoe, installing my solar power systems, and much more.

But if you search on: "power tool start stop switch" you will find many options for around $10.
