2023-03-30 (Th) GrinderCompass First build

I cut all the parts and assembled the spinner with a brass 1/4-20 bolt and a couple of brass nuts. The magnet stacks held in place better than I expected. At first glance, after cutting, I assumed the edges would be too brittle, but everything has kept sturdy. I suspended it from a string, which reliably pointed north, despite twisting the line.

The base is currently held together with nylon bolts and long plastic standoffs. I am curious if this will be the correct height when the spinner is functional, but it keeps the parts tidy.

The pendulum needs work. I thought there would be sufficient clearance between the brass nuts and bolts, but it will not work. I added a hole for the pin where it would swing, but it did not cut, so I had to force it through, and it became crooked, plus it was too low. The hex holes were the wrong size. The unit will require a heavy overhaul.
