I've watched plenty of YouTube videos and read a bunch of articles so I think I understand the science of soldering. Now, I just have to come up with my own technique. The copper wire I'm using is soft and pliable, so I am able to twist and bend it. Once I get the soldering technique figured out, I'll be able to get really creative!
Got the copper racks all soldered. Went pretty easy except for holding the pieces in place while soldering. The alligator clip was a little rough on the copper due to it's teeth, and because of the length it was hard to clip the pieces together and still have room to work. I've found some solutions on Amazon, such as cross locking tweezers and locking forceps. They were only around $4.00 with prime shipping, so I'll probably get them.
I sprayed the racks in flat black and they came out pretty good. Definitely not perfect, but I'll just call them "whimsical". I fell asleep last night redesigning them in my head. They say dreaming is the best way to come up with solutions to your problems, so we'll see how the next batch turns out.
The finished racks are pretty cute, and I think I'll make several more until I feel confident in making the special one for the barn kitchen's rooster plates. Maybe I can sell the practice ones on eBay. I can always use more "mini money"!
