Hi, this is my first post, I've been gathering parts needed to build the midiboxsid, and I'm trying to find raw aluminum sheets I can use for the panel. What are some sources either local (I'm in the US, chicago area), or internet where I can buy something like 6"x20"x0.125" or bigger aluminum sheet (or 16 gauge thickness)... I've seen some things on ebay, but I was hoping metal would be less expensive. Also, does anyone have opinions on using aluminum baking pans? I've seen some that are sized 18"x24"x16gauge, 3003 aluminum alloy, and only like $7. Is there a reason the aluminum in these wouldn't work well? I figured I'd cut out what I need from the pan... I've also considered 16 gauge steel sheet (I found this at HomeDepot), and acrylic .25" (also at HomeDepot). Though I'm afraid of the steel rusting (it wasn't "stainless") though maybe paint would stop that (I don't know), and the acrylic not being as nice as metal... was thinking of painting the acrylic some color... I'm using an old C64 case... So, anyone got some cheap sources for sheet metal? I'm happy drilling and using a nibbler tool to create my own, assuming nibbler works on 16gauge thickness, no idea, otherwise thinking jigsaw...
