What's wrong with hot glue?...I use it all the time, I mean it has it's place, especially to tack pieces in place till a permanent attachment method is employed on a proven concept...when I sit down at my workbench, 1st thing I do is plug in my soldering iron and my hot glue gun...it's not about being a purist, it's about being practical...and if you have an old soldering iron with a cutter tip, it's a lot more "undoable" than other methods
