We had a slightly shorter week than usual due to Election Day on Tuesday, but the students were still working hard in the shop on all their projects. Let’s get to some of the students work from this week.
Senior Santanna Russell continues his work on a robotic arm. His latest blog post states:
Me?…. goongaga
most of my time this week was spent as usual, modeling and printing
after last week’s printer trouble, it makes me happy to say that I was able to print the elbow, bicep joints, forearm joints, and hopefully forearm. the elbow came out near perfect, because I used one of our fusion printers it doesn’t look as good as I wanted it to be, but it works as I need it to. The forearm’s print didn’t finish by the time I had to leave, so I’m hoping it came out okay. There isn’t a whole lot to say about the joints, but I am a little worried. the space between the screw and the motor is really thin, so I’m praying it comes out okay.
I did a lot of modeling this week. a lot of my time was spent on the elbow and forearm, but a larger chunk was taken up by a new gripper remake. I don’t like the way the gripper looks. I also don’t like the way it looks next to the rest of the parts, so I’m doing it’s third remake. the gripper’s body is the weirdest out of all the parts, instead of the motor peaking out of the sides, it peaks out through the top, and that weirdly makes it harder to model. the old one looks lanky and stocky at the same time, so with this remake I’m trying to make it look more uniform, especially with the rest of the parts.
The work on his arm is pretty remarkable, and you should read more about it on his website at this link.
Junior Euan Rees is working on an electronic dish washing device. It’s a unique project and he discusses his latest updates on his blog.
This week, from the recommendations of Mr. Christy: my shop teacher. I chose to test another one of our motors in shop before proceeding with my plan to buy another motor online. I think this is helpful as the motor I chose had a far higher torque than any other motor that I have tested in the past. This will allow me to also be able to know exactly what a good amount of torque should be for the cleaner, as well as if the 100 rpm that the motor comes with is sufficient or if more should be necessary.
After getting this motor, I next proceeded to taking its dimensions and creating a CAD model for the design, after multiple test and many tweaks to the spacing I eventually got the dimensions right and assembled it. For Friday I hope to drill out the connecter to the motor attachment to it to house larger motor.

The Sophomores spent the week in the machine shop learning how to use our milling machines. They are making Turner’s Cubes. Back to circuitry for them next week.
