My first design for the reel crank (here in brass) was too “heavy” in the middle.
So back to the drawing board. Here I have reduced the diameter of the center circle, and moved one small inside radius to make the arm thinner. All curves are arcs of a circle.
Fabrication starts with drilling location holes for the handle, counterweight, and shaft.
Then I plunge mill four small holes which become inside radii.
All the larger arcs are milled on the rotary table. The tool plate was carefully planned to hold the material in the correct positions.
