I will let you know how this works out. The problem I'm running into now is the machine, and all of the 20 knockoffs on Amazon seem to be limited to 200mm x 130mm, or about 8" x 5". I can find old style aluminum placards that are 5 x 7, but they won't fit on the machine because they are portrait, not landscape like the machine is setup for. And all of the new style general information style signs are even larger. Looks like I need to custom make the entire sign by stamping everything, not just filling in the blanks on a pre-made sign. Or find a different class machine. Either way things seem to be getting out of hand on this, just might buy an individual letter set and put the time in.
