Week of 9/12/22
Finishing the Turner’s Cube
During the beginning of the week I finished the Turner’s Cube. I first finished facing the cube to 1x1x1in, then I moved setting up the machine for making the pockets in the cube. To do that I first found the correct bit for making the pockets, then I set up the offsets in the Milling Machine. Once I had finished that I started to make the GCODE on the milling machine, having it drill one pocket 0.15in deep, then a second smaller pocket the same depth.
Once everything was set up I found the exact center of the cube by using the Haimer 3D Sensor to measure the distance across the cube then dividing it by two.

After I had centered the milling machine on the cube, I ran the GCODE on the first side watching it carefully to make sure it was doing what I wanted. Once that had finished I rotated the cube and repeated it on all sides, leaving me with an almost finished product I just needed to sand.

Starting Wrench Project
I am on the rowing team at my school, and our boats use either 7/16in or 10mm bolts depending on the boat. Sadly I have not been able to find a wrench with a 7/16in and 10mm side, so I decided to make one.
During the last two days of the week I modeled the wrench in Fusion360. The model had to be able to be projected onto a 2D plane so that I could make it with our Plasma Cutter. After I modeled the wrench I laser cut a model out of cardboard so that I could test my design and see how I could improve it. My first edition had square corners that we likely to break, so I rounded them more. After my second edition I did not change anything structurally and just added text labeling which side is 10mm and which side is 7/16.

After I laser cut the cardboard models I brought them to crew practice to make sure that they fit the bolts they were made for, and they did, so I plan to make the wrenches out of steel next week.
