Motorizing my Wondermill Jr. Deluxe with solar power

Using "Stuff" I had laying around the shop I convert my manual crank grain mill to an electric mill and powering it with solar power.

Excellent job you've done. I ordered the drill bit and am thinking of getting the pully and bike gear too. I like the hopper extender you made. What software did you use to design it? I have an Ender 3, I use Autodesk Fusion 360, IdeaMaker, and Ultimaker-Cura software for the final print.

Outstanding!

Now I know what to do with all that stuff I've been saving because 'i might need it someday".
Good ideas. :)

What size are the 2 pulleys (top large & small bottom one) and what is the rpm of the small pulley?
