I did a few upgrades on the CNC to make it more rigid, but the gantry still isn't rigid enough and has some wiggle. The y-axis pipes (longest axis) were replaced with 8020 beams and v-groove bearings. The z-axis was completely replaced with a metal one from eBay that is completely rigid. However, the gantry is just too weak and the left and right sides of it can move back and forth.
In general, however, the CNC is much better and I used it to cut out fins for other TARC teams' rockets.

The End of Summer
Well, summer break is coming to an end and the beginning of 11th grade is fast approaching. I did have some fun, even with all the SAT prep.
Just over a week ago I went to Fremont Peak State Park at San Juan Bautista, CA to do some astrophotography because the light pollution there is far lower than in the city.
I also went to Hawaii.
