Hey guys, So I've been reading through a lot of different project logs and got inspired to do some work of my own. I just need a little help getting started. I am planning on building a rig about the size of a cable box. I don't know how thick of metal I should be using for that though reading through some of the threads it looks like 2mm would be good but I am not sure; any suggestions would be great. Since this is my first time dealing with raw materials I have no clue where to buy stuff. Right now it is looking like im going to be needing a 20inx20in sheet of aluminum would a home depot/lowes sell something like that or am I going to have to find a specific shop for that? Thanks in advance guys!
