Hey there, Charlie!
I finally have almost everything I need: Slides, solder, flux, flux brush, alcohol for cleaning the slides, 1/4" copper foil (I got the kind that looks silver on the back), something to burnish the foil with, bits of cool stuff for my collage, soldering iron, loop to attach to the top, glue...
What I'm missing at this point is something to hold the slide for soldering. I no longer have my "third hand" tool. Maybe a small vise or something would work.
Everything is laid out on my kitchen table. I'm ready. Almost :-)
What questions did you have? I bet the group here could answer them.
Oh, and I got some silica gel today and have a bunch of tiny flowers from my garden drying as we speak. Yay!
