I completed my petal ring this morning.
I should have waited for some guidance, since I started to rivet the whole thing together before I spoke to the instructor about it, and now the petals are immobile.
You live and learn. I did get some tips on how to achieve this, but too late for this ring.
I still like the ring a lot, so no harm done.
After I completed the ring, we had demonstrations on a bunch of ways to solder. The demos took almost the entire class. The last 1/2 hour of class, I practiced soldering with some scrap copper. I sweat soldered some sheet scraps to a square piece of copper, and then soldered some wire onto the square as well. It wasn't any kind of design that I am proud of... it was just for practice, so I didn't take pics.
We will start on Project 3 in two weeks since next Saturday is spring break. I have two weeks to come up with a design that incorporates soldering sheet and wire, with any processes we have learned up to this point. I better put on my thinking cap.
