Getting to the point where I can do these in my sleep... These are the "labs" I have my sheet metals students do before they can pick a project. The first is a Joining Lab, where they get to practice measuring, marking, cutting, bending, and different joining processes. I've thrown dozens of these out but they seem to keep showing up, usually whenever I have a metals class going on. The boxes I tend to save- they make great organizers in all of my drawers and lockers.
Today was our last flight day for the rubber band powered airplanes. Had maybe a little more than 1/3rd of the 14 or so airplanes make it through all of the days looking like they can still fly. Kids can be pretty rough on a "gentle" toss. That, and meeting a brick wall 20 feet up can cause some damage! They tend to get excited and toss them too hard, meaning they shoot straight up in the air. Three of the planes below are headed for a good crash landing...
Kinda hard to get pictures of them in the air. The gym has some huge air vents in the ceiling and they create some serious turbulence. Makes for interesting flying! I always enjoy teaching this unit and it seems like the kids do too. Test tomorrow and then we move on to Lego Robotics.
Still dabbling with the TIG and aluminum. Trying to get at least 15 minutes a day in, and I've been getting at least that. My little 1/8" sheet of aluminum is now almost 1/2" thick, and I got a darn near perfect bead on some 20 gauge. Course, when I tried to replicate it on a fresh piece so I could take a picture, I was running too slow so the base metal got too hot giving a poor finish. At least I'm not burning holes anymore.
Might be MIA for the next few days- my book showed up which means I have 909 pages to get through!
