Hi everyone! It's been a while since my last post, almost 4 months. Rest assured, I haven't given up. I'm still working on the project. It's just really hard right now to work out times to come in and work on the rollercoaster with my teacher. Even though I'm going to school in person now, he's still really busy. In any case, I was recently able to go in and work finally! Right now, I'm working on figuring out a process I can use to bend PVC. My solution was to "bake" sand in an aluminum pan until it was hot enough, then pour the hot sand into the PVC pipe as it lays over my form. However, things didn't exactly go as planned. The aluminum pan was too flexible, and as my teacher and i tried to pour sand into the pipe, it spilled everywhere. Because of this, the sand ended up cooling off way too much and so I didn't really get the bend I was looking for. I'm trying to figure out a solution to that right now; a sand delivery device that will make it easier to heat up and then pour the sand into the pipe.
