2023-09-11 (M) GrinderCompassMKII COMPLETED

I changed the enclosure dimensions by two millimeters in each direction to make it shorter and wider. I fired up the laser, and while it cut, I began cutting another axle. This time, I made it from brass instead of aluminum, but more importantly, I used 1/8" stock and the standard rotary tool collet instead of a chuck, so the workpieces were centered better than before. The result was a uniform axle that did not need any adhesive to keep it from wobbling.

When the laser finished, I did a test fit, and everything fit snuggly. The top used to have a hexagon hole, but I replaced it with a circular hole so the top bolt head could pass and because some solder residue impeded the top from sitting flush. I tried using the larger steel bearings on the magnet, but they brushed against the string, so I returned to the small ones.

I could not feel any sensation from the device as I jiggled, but I may be able to hear the collision of the bead and bearing. This project is complete, so I can develop MKIII as I work on other projects.
